Description

Technical Field

[0001] This application relates to the field of grinding machine technology, and more particularly to a through-type double-end face grinding machine. Background Technology

[0002] A grinding machine is a machine tool that uses grinding wheels to grind the surface of a workpiece, thereby improving the surface accuracy of the workpiece.

[0003] In related technologies, a double-end face grinder is designed, comprising a machine body with a housing on its surface. Inside the housing are two sets of symmetrical grinding head components. Each grinding head component includes a grinding head spindle, grinding wheels, and a lead screw feed mechanism. The grinding wheels are connected to the end wall of the grinding head spindle, and the grinding head spindle is connected to the lead screw feed mechanism, which drives the grinding head spindle and grinding wheels to rotate. A grinding channel is formed between the two grinding wheels. A feed port is opened on one side wall of the housing, and an discharge port is opened on the side wall of the feed port inside the housing. Both the feed port and the discharge port are connected to the grinding channel. A conveying mechanism for transporting workpieces is provided inside the housing. When grinding a workpiece, the workpiece to be processed is placed into the grinding channel through the feed port. As the conveying mechanism operates, the workpiece is moved through the two grinding wheels, thus enabling double-sided grinding of the workpiece.

[0004] Regarding the aforementioned technologies, the inventors discovered that the automatic feeding capability of the double-end face grinder is poor. If the workpiece is strip-shaped, one end will protrude outside the housing during grinding. Under its own weight, the workpiece will bend, affecting the grinding quality. Operators need to lift the workpiece at the feed inlet to keep it straight. If the workpiece is block-shaped, it limits the number of pieces that can be fed at one time, requiring operators to continuously feed the workpiece at the feed inlet, increasing the workload and affecting the grinding efficiency. Therefore, improvements are needed. Summary of the Invention

[0005] To improve the automated feeding capability of double-end grinding machines, this application provides a straight-through double-end grinding machine.

[0006] This application provides a through-type double-end face grinder with the following technical solution:

[0007] A straight-through double-end face grinder includes a machine body and a housing disposed on the surface of the machine body. A feed inlet is provided on one side wall of the housing. A loading platform is provided on one side of the machine body. A transmission mechanism is provided on the loading platform. Two limiting baffles are provided on the surface of the loading platform, forming a limiting channel for the workpiece to pass through between the two limiting baffles. The limiting channel is connected to the feed inlet. A loading mechanism is provided above the loading platform, and the loading mechanism is connected to the limiting channel. A pushing mechanism is provided at one end of the loading platform near the housing, and the pushing mechanism drives the workpiece in the limiting channel into the feed inlet.

[0008] By adopting the above technical solution, when the workpiece to be ground is long and narrow, it can be placed directly in the limiting channel. Through the action of the transmission mechanism and the pushing mechanism, the workpiece can enter the feed port for grinding. During this process, the loading platform and the transmission mechanism provide support for the long and narrow workpiece, making it less prone to deformation under its own weight, thus enabling stable grinding. When the workpiece to be ground is blocky, it is placed in the loading mechanism, which continuously adds workpieces to the limiting channel. Under the action of the transmission mechanism and the pushing mechanism, the machine body can continuously grind the blocky workpiece, thereby improving the loading efficiency and the continuity of work. The straight-through double-end face grinder of this application can stably and continuously load both long and narrow and blocky workpieces, effectively improving the quality and efficiency of grinding, and has high practicality.

[0009] Preferably, the feeding mechanism includes a feeding frame, a feeding belt, and a feeding pipe. The feeding frame is disposed on the surface of the feeding platform, the feeding belt is rotatably connected to the feeding frame, and the feeding pipe is disposed at the end of the feeding frame away from the machine body. The feeding pipe is connected to the feeding belt. The feeding pipe includes several interconnected pipe fittings, one end of each pipe fitting is inclined towards the feeding platform, and the inclination directions of adjacent pipe fittings are opposite. The pipe fittings away from the feeding frame are connected to a limiting channel. A pushing cylinder is disposed between adjacent pipe fittings, and the piston rod of the pushing cylinder is used to push the workpiece in the upper pipe fitting into the lower pipe fitting.

[0010] By adopting the above technical solution, the block-shaped workpiece to be processed is conveyed on the feeding belt. When the workpiece enters the feeding pipe, it slides along the inclined inner wall of the feeding pipe. When the workpiece moves to the junction of two pipes, the pusher cylinder can push the workpiece from the previous pipe into the next pipe. At this time, the workpiece will slide along the inclined inner wall of the pipe. After multiple sliding, the workpiece enters the limiting channel and is transported by the transmission mechanism, thereby realizing continuous feeding. The feeding mechanism of this application increases the length of the pipe, so that the feeding mechanism of this application can accommodate more workpieces for transmission, which improves the problem that the workers need to be at the feed inlet at all times to feed workpieces and cannot leave the feed inlet to do other work, resulting in low work efficiency. It improves the continuity and efficiency of grinding processing.

[0011] Preferably, the end of the feeding pipe near the limiting channel is connected to a feeding shell, the bottom wall of the feeding shell is provided with a feeding port for the workpiece to enter the limiting channel, and a feeding assembly is provided inside the feeding shell, the feeding assembly is used to move the workpiece inside the feeding shell to the feeding port.

[0012] By adopting the above technical solution, the unloading shell can receive the workpieces output from the feeding pipe, so that the workpieces will not directly enter the limiting channel, thus improving the problem of excessive accumulation of workpieces and blockage in the limiting channel. Driven by the unloading component, the workpieces can move sequentially to the unloading port for unloading, improving the orderliness and safety of the entire feeding and grinding process.

[0013] Preferably, the feeding assembly includes a rotating component, a separating turntable, a mounting block, several magnetic components, and a separating plate. The rotating component is connected to the inner top wall of the feeding housing. The separating turntable and the mounting block are both sleeved on the peripheral wall of the output shaft of the rotating component. The mounting block is located on the side of the separating turntable closer to the rotating component. Several magnetic components are hinged to the side wall of the mounting block. The separating turntable has several clearance notches extending through it along the thickness direction. The magnetic components are magnetically attracted to the workpiece through the clearance notches. The separating plate is connected to the inner wall of the feeding housing. The starting end of the separating plate is located above the feeding port. After the rotating component drives the separating turntable and the magnetic components to rotate, the separating plate separates the magnetic components from the separating turntable.

[0014] By adopting the above technical solution, the workpiece still retains a certain kinetic energy when it detaches from the pipe. The workpiece will slide to the bottom of the separating turntable. At this time, the magnetic component and the workpiece are magnetically attracted to each other and will overlap on the surface of the separating turntable. The gap provides an attraction to the workpiece. Under the action of the rotating component and the magnetic component, the separating turntable will drive the workpiece to rotate. When the workpiece rotates to the discharge port, the separating plate begins to abut between the magnetic component and the separating turntable, thereby cutting off the magnetic attraction between the magnetic component and the workpiece. When the workpiece loses the attraction of the magnetic component, the workpiece will fall and pass through the discharge port, and finally enter the limiting channel, where it will be transported by the transmission mechanism. The feeding mechanism of this application has a high degree of automation. Several magnetic components installed on the side wall of the mounting block can continuously move the workpiece with the drive of the rotating component, making the entire feeding process more efficient and improving work efficiency.

[0015] Preferably, the feeding assembly further includes a positioning disk, which is sleeved on the peripheral wall of the output shaft of the rotating component. The positioning disk is located on the side of the mounting block away from the dividing turntable. The bottom wall of the positioning disk is provided with a plurality of elastic elements, which correspond one-to-one with magnetic elements. The end of the elastic element away from the positioning disk is connected to the corresponding magnetic element, and the elastic element drives the magnetic element to rotate in the direction away from the dividing turntable.

[0016] By adopting the above technical solution, the elastic element facilitates the separation of the magnetic element from the separating turntable by the separating plate. The elastic element continuously provides a pulling force towards the positioning plate to the magnetic element, making it easier for the magnetic element to be separated from the separating turntable when it is subjected to the action of the separating plate, thus improving the convenience of unloading from the separating turntable. At the same time, the positioning plate allows the magnetic element to be stably positioned between the positioning plate and the separating turntable, limiting the large range of rotation of the magnetic element and enabling the magnetic element to maintain a stable working state.

[0017] Preferably, the surface of the loading platform is provided with a hidden groove, which is located between the two limiting baffles. A lifting cylinder is provided in the hidden groove, and a lifting block is provided on the piston rod end wall of the lifting cylinder. A bearing block is provided on the side of the lifting block away from the lifting cylinder. The lifting cylinder drives the lifting block and the bearing block to abut into the unloading port. A buffer is provided on the bottom wall of the bearing block, and the end of the buffer away from the bearing block is connected to the lifting block. A pusher assembly is provided on the surface of the loading platform. The pusher assembly is used to push the workpiece on the surface of the bearing block into the limiting channel.

[0018] By adopting the above technical solution, when the unloading assembly unloads the workpiece, the lifting cylinder drives the lifting block and the bearing block into the unloading port, so that the bearing block can catch the workpiece. This improves the problem that the workpiece has a large kinetic energy when it falls from the unloading housing onto the surface of the transmission mechanism, which could cause damage to the transmission mechanism and the workpiece, thus improving the safety of the grinding machine of this application. At the same time, the buffer can buffer the impact force when the workpiece falls onto the surface of the bearing block, further protecting the structural safety of both. The booster assembly can move the workpiece from the surface of the bearing block to the surface of the transmission mechanism for further conveying, thereby improving the overall automation capability.

[0019] Preferably, the booster assembly includes a limiting sleeve, a push rod, a reset component, a sliding groove, a pushing protrusion, and a connecting rod. The limiting sleeve is disposed on the side of the support block opposite to the limiting baffle. The push rod is slidably connected to the inner wall of the limiting sleeve, and the sliding direction of the push rod is consistent with the length direction of the limiting channel. The reset component is disposed between the side wall of the push rod and the inner wall of the limiting sleeve, and the reset component drives the push rod to slide and then reset. The sliding groove is disposed on the side of the limiting sleeve opposite to the lifting block, and the pushing protrusion... The pusher is slidably connected to the sliding groove. The side wall of the pusher is provided with a locking block. The side wall of the sliding groove is provided with a locking groove through which the locking block passes and slides. The locking groove is opened in the vertical direction. One end of the connecting rod is hinged to the side wall of the lifting block, and the other end is hinged to the side wall of the locking block extending out of the locking groove. When the lifting block moves, it drives the pusher to slide in the sliding groove. After the pusher slides, it abuts against the push rod and pushes the push rod to slide towards the limiting baffle.

[0020] By adopting the above technical solution, when the lifting cylinder drives the lifting block to move towards the hidden groove, the lifting block can drive the pushing protrusion to move through the connecting rod. Due to the abutment relationship between the locking block and the inner wall of the locking groove, the pushing protrusion moves vertically along with the lifting block. During the movement of the pushing protrusion, the side wall of the pushing protrusion abuts against the push rod. As the diameter of the pushing protrusion increases, the push rod will also be pushed towards the limiting baffle. When the push rod moves, it abuts against the workpiece on the surface of the bearing block, so that the workpiece can gradually detach from the bearing block and fall onto the surface of the transmission mechanism for conveying. The booster mechanism of this application does not have a direct power component. It uses the power of the lifting cylinder to push out the workpiece, which has strong synchronization and high automation performance, effectively saving costs while improving the convenience of loading.

[0021] Preferably, the feeding mechanism includes a guide rail, two guide plates, two rollers, and a positioning device, with each guide plate and roller corresponding to the other. The guide rail is connected to the side wall of the housing, and both guide plates are slidably connected to the guide rail, forming a guide channel between the two guide plates for the workpiece to pass through. The guide channel is connected to a limiting channel. A guide groove is provided through the side wall of each guide plate, and the rollers are rotatably connected to the inner wall of the guide groove of the corresponding guide plate. The two rollers drive the workpiece into the feed inlet. The positioning device is located on the surface of the machine body, and both guide plates are connected to the positioning device. The positioning device drives the guide plates to move along the length of the guide rail.

[0022] By adopting the above technical solution, while the two rollers rotate, they can abut against the side wall of the workpiece entering the guide channel, thereby pushing the workpiece towards the feed port, which improves the ease of loading and automation capability of the grinding machine of this application; at the same time, in the actual grinding process, different types of workpieces have different sizes. By setting a positioning device, the guide plate can move along the length of the guide rail, thereby adjusting the size of the guide channel to accommodate the loading of workpieces of different sizes, which has high applicability.

[0023] Preferably, the limiting baffle has a clearance cavity on its surface, a push wheel is rotatably connected inside the clearance cavity, and a push port for the push wheel to extend out is provided on the side wall of the clearance cavity near the limiting channel.

[0024] By adopting the above technical solution, a push wheel is set in the relief cavity, which enables the workpiece to be continuously transported under the action of the push wheel and the transmission mechanism, thereby improving the feeding convenience and overall automation capability of the grinding machine of this application, and making it highly practical.

[0025] Preferably, each of the two limiting baffles has a driving member on its opposite sidewall. The driving member is connected to the surface of the loading platform and drives the two limiting baffles to move toward each other or away from each other. The surface of the loading platform is provided with limiting bolts, and the limiting baffles have a waist-shaped groove through which the limiting bolts pass and slide along the thickness direction.

[0026] By adopting the above technical solution, the driving component can flexibly adjust the position of the two limiting baffles to adjust the size of the limiting channel to accommodate the transportation of workpieces of different specifications. By opening the waist-shaped groove and setting the limiting bolt, the movement direction of the limiting baffles is restricted, thereby maintaining the relative parallelism of the two limiting baffles and improving the accuracy of the limiting baffles in limiting the workpiece.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When the workpiece to be ground is long and narrow, the feeding platform and the conveying mechanism provide support for the long and narrow workpiece, making it less likely to deform under its own weight, thus enabling stable grinding. When the workpiece to be ground is blocky, the feeding mechanism continuously adds the workpiece to be processed into the limiting channel. Under the action of the conveying mechanism and the pushing mechanism, the machine body can continuously grind the blocky workpiece, effectively improving the feeding efficiency and work quality of grinding, and has high practicality.

[0029] 2. Setting a discharge housing and discharge assembly at the end of the feeding pipe can make the conveying of workpieces through the feeding pipe more orderly, reduce the probability of workpiece blockage in the limiting channel, and improve the safety and efficiency of the grinding machine of this application.

[0037] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0038] Example 1:

[0039] Embodiment 1 of this application discloses a through-type double-end face grinder. (Refer to...) Figure 1 It includes a machine body 1 and a box 2 set on the surface of the machine body 1. A feed inlet 21 is opened on one side wall of the box 2. A feeding platform 3 is set on one side of the machine body 1. The feeding platform 3 is connected to the machine body 1 by bolts. The feeding platform 3 is set on the side of the box 2 where the feed inlet 21 is opened.

[0040] Reference Figure 1The surface of the loading platform 3 is provided with two parallel limiting baffles 32. The length direction of the limiting baffles 32 is consistent with the length direction of the loading platform 3. A limiting channel 33 for the workpiece to pass through is formed between the two limiting baffles 32. The limiting channel 33 is connected to the feed port 21. A relief cavity 321 is opened on the surface of the limiting baffles 32. A number of waist-shaped grooves 326 are opened through the bottom wall of the relief cavity 321. The number of waist-shaped grooves 326 are evenly distributed along the length direction of the limiting baffles 32. The surface of the loading platform 3 is provided with a number of... Each limiting bolt 325 corresponds to a slotted groove 326. The peripheral wall of the limiting bolt 325 abuts against the inner wall of the slotted groove 326. The end of the limiting bolt 325 passes through the corresponding slotted groove 326 and abuts against the bottom wall of the relief cavity 321. This allows the limiting baffle 32 to slide under the mutual abutment of the slotted groove 326 and the limiting bolt 325, thereby adjusting the size of the limiting channel 33. This enables the grinding machine of this application to accommodate more workpieces of different specifications and sizes, improving its applicability.

[0041] Reference Figure 1 A conveying mechanism 31 is rotatably connected to the loading platform 3. The conveying mechanism 31 is used to transport the workpiece in the limiting channel 33. The transport direction of the conveying mechanism 31 is consistent with the length direction of the limiting channel 33. In this embodiment, the conveying mechanism 31 is a conveyor belt. When the operator places the workpiece in the limiting channel 33, the conveying mechanism 31 will move the workpiece toward the feed port 21 to achieve automatic loading. If the workpiece is long and narrow, the conveying mechanism 31 and the loading platform 3 can provide support for the workpiece, improving the problem of bending of the workpiece due to its own weight, which leads to errors in grinding. When the workpiece to be processed is blocky, the limiting channel 33 can also accommodate multiple workpieces. Under the action of the conveying mechanism 31, continuous loading is achieved, which improves the automated loading capability of the grinding machine of this application.

[0042] Reference Figure 1 A pushing mechanism 5 is provided between the loading platform 3 and the machine body 1. The pushing mechanism 5 is used to transport the workpiece in the limiting channel 33 to the inlet 21.

[0043] Reference Figure 1The feeding mechanism 5 includes a guide rail 51, two guide plates 52, two rollers 53, and a positioning device 54. The guide plates 52 and rollers 53 correspond one-to-one. The guide rail 51 is bolted to the side wall of the housing 2. Both guide plates 52 are slidably connected to the guide rail 51, forming a guide channel 522 between the guide plates 52 for the workpiece to pass through. The guide channel 522 is connected to both the feed inlet 21 and the limiting channel 33. The positioning device 54 is located on the surface of the machine body 1, and both guide plates 52 are connected to the positioning device 54. The device 54 can drive the guide plate 52 to move along the length direction of the guide rail 51. In this embodiment, the positioning device 54 adopts a handwheel and lead screw connection method. The lead screw is connected to the guide plate 52. By rotating the handwheel, the guide plate 52 can be driven to slide along the length direction of the guide rail 51. When the two guide plates 52 slide along the length direction of the guide rail 51, the size of the feed port 21 can be adjusted to change with the change of the limiting channel 33, so as to adapt to the entry of workpieces of different specifications and sizes into the box 2.

[0044] Reference Figure 1 The guide plate 52 has a guide groove 521 through the side wall, which is connected to the guide channel 522. The roller 53 is rotatably connected to the inner wall of the guide groove 521 of the corresponding guide plate 52. One end of the roller 53 passes through the guide groove 521 and enters the guide channel 522. The two rollers 53 can abut against the workpiece and drive the workpiece to move towards the feed port 21, which improves the feeding efficiency of the grinding machine of this application.

[0045] The implementation principle of a straight-through double-end face grinder in Embodiment 1 of this application is as follows: When a workpiece needs to be ground, the operator places the workpiece into the limiting channel 33. Under the drive of the transmission mechanism 31 and the pusher mechanism 5, the workpiece will move along the direction of the limiting channel 33 and enter the feed port 21, thereby performing grinding within the housing 2, thus realizing automated feeding of the grinder.

[0046] Example 2:

[0047] The difference between Embodiment 2 and Embodiment 1 of this application is as follows:

[0048] Reference Figure 2 A feeding mechanism 4 is provided above the feeding platform 3. The feeding mechanism 4 is located at the end of the feeding platform 3 away from the machine body 1. The feeding mechanism 4 is connected to the limiting channel 33 to extend the transmission distance of the limiting channel 33. This allows for the continuous conveying of a larger number of workpieces when the workpiece to be processed is in block shape, thereby further enhancing the continuous feeding performance of the grinding machine.

[0049] Reference Figure 2 and Figure 3The feeding mechanism 4 includes a feeding frame 41, a feeding belt 42, and a feeding pipe 43. The feeding frame 41 is disposed on the surface of the feeding platform 3 and is located above the limiting channel 33. The length direction of the feeding frame 41 is consistent with the length direction of the limiting channel 33. In this embodiment, the bottom wall of the feeding frame 41 is provided with several support feet, which are connected to the surface of the feeding platform 3 by welding to support the feeding frame 41. The feeding belt 42 is rotatably connected to the feeding frame 41, thereby enabling the workpiece to move and transport along the length direction of the feeding frame 41.

[0050] Reference Figure 3 The feeding pipe 43 is located at the end of the loading rack 41 away from the machine body 1. The feeding pipe 43 is connected to the feeding belt 42. When the workpiece is transported along the feeding belt 42, it will enter the feeding pipe 43. The feeding pipe 43 includes three interconnected pipe sections 431. Adjacent pipe sections 431 are connected by welding. The first pipe section 431 is connected to the feeding belt 42. The end of this pipe section 431 away from the feeding belt 42 is inclined towards the loading platform 3. This pipe section 431 is located directly above the limiting channel 33. The second pipe section 431 is located at the end of the first pipe section 431 away from the feeding belt 42, and the second section... The end of the pipe fitting 431 facing away from the first pipe fitting 431 is inclined toward the feeding platform 3; the third pipe fitting 431 is located at the end of the second pipe fitting 431 facing away from the feeding belt 42, and the end of the third pipe fitting 431 facing away from the second pipe fitting 431 is inclined toward the feeding platform 3. In this embodiment, the third pipe fitting 431 is parallel to the first pipe fitting 431 and located directly below the first pipe fitting 431. The cross-section of the three pipe fittings 431 is Z-shaped. When the workpiece enters the feeding pipe 43, it will slide along the inclined inner wall of the pipe fitting 431, thereby realizing the transportation of the workpiece.

[0051] Reference Figure 3 A pusher cylinder 432 is provided between adjacent pipe fittings 431. The end of the pusher cylinder 432 is welded to the outer wall of the pipe fitting 431, and the piston rod passes through the outer wall of the pipe fitting 431 and enters the interior of the pipe fitting 431 to push the workpiece that has slid to the end of the previous pipe fitting 431 into the next pipe fitting 431, so as to realize the continued conveying of the workpiece.

[0052] Reference Figure 3 and Figure 4The end of the third section pipe 431 opposite to the second section pipe 431 is connected to the unloading housing 6 by welding. The bottom wall of the unloading housing 6 has a through-hole 61, which is located above the limiting channel 33. The unloading assembly 7 is provided at the top inside the unloading housing 6. The workpiece that slides from the third section pipe 431 into the unloading housing 6 will be moved to the unloading port 61 by the unloading assembly 7, thereby realizing orderly unloading, improving the problem of workpiece blockage in the limiting channel 33, and improving the working safety of the grinding machine of this application.

[0053] Reference Figure 4 and Figure 5 The feeding assembly 7 includes a rotating component 71, a separating turntable 72, a mounting block 73, two magnetic components 74, a separating plate 75, and a positioning plate 76. The rotating component 71 is connected to the inner top wall of the feeding housing 6. In this embodiment, the rotating component 71 is a motor. The separating turntable 72, the mounting block 73, and the positioning plate 76 are all sleeved on the peripheral wall of the output shaft of the rotating component 71. The separating turntable 72 is located at one end near the feeding port 61, the mounting block 73 is located at one end of the separating turntable 72 near the rotating component 71, and the positioning plate 76 is located at one end of the mounting block 73 away from the separating turntable 72.

[0054] Reference Figure 4 and Figure 5 Both magnetic components 74 are hinged to the side wall of the mounting block 73. In this embodiment, the magnetic component 74 is a magnet, and the dividing turntable 72 is made of aluminum. The magnetic component 74 can be magnetically attracted to the workpiece. To improve the attraction between the magnetic component 74 and the workpiece, the dividing turntable 72 is provided with several clearance notches 721 along the thickness direction. The clearance notches 721 are evenly distributed along the circumferential direction of the dividing turntable 72. When the magnetic component 74 rotates with the rotating component 71 to above the workpiece, the magnetic component 74 will be attracted by the workpiece and rotate towards the dividing turntable 72. At this time, the workpiece will be attracted to the bottom wall of the dividing turntable 72 under the action of the magnetic component 74. When the rotating component 71 rotates again, it will rotate to above the discharge port 61, waiting to be discharged.

[0055] Reference Figure 3 and Figure 5 The separating plate 75 is welded to the inner wall of the unloading housing 6. In this embodiment, the separating plate 75 is a thick wooden board and is semi-circular. Both ends of the separating plate 75 are provided with inclined guide surfaces. The starting end of the separating plate 75 is located above the unloading port 61. When the rotating component 71 drives the separating turntable 72 and the magnetic component 74 to rotate, the separating plate 75 will gradually be inserted between the magnetic component 74 and the separating turntable 72 through the inclined guide surfaces, thereby separating the magnetic component 74 from the separating turntable 72. Due to the presence of the separating plate 75, the magnetic force of the magnetic component 74 will no longer be able to firmly attract the workpiece. The workpiece that loses its magnetic force will fall into the unloading port 61 and then enter the limiting channel 33 to realize automated unloading.

[0056] Reference Figure 5 Two elastic elements 761 are glued to the bottom wall of the positioning disk 76. The elastic elements 761 and the magnetic elements 74 correspond one-to-one. In this embodiment, the elastic element 761 is a spring. The end of the elastic element 761 away from the positioning disk 76 is glued to the corresponding magnetic element 74. Under the action of the elastic element 761, the magnetic element 74 always maintains the tendency to rotate in the direction of the positioning disk 76, which facilitates the separation plate 75 to separate the magnetic element 74 from the separating turntable 72.

[0057] Reference Figure 4 and Figure 6 The surface of the loading platform 3 is provided with a hidden groove 34, which is located between the two limiting baffles 32 and directly below the discharge port 61. A lifting cylinder 35 is embedded in the hidden groove 34. The piston rod of the lifting cylinder 35 is set towards the outside of the hidden groove 34. A lifting block 36 is welded to the end wall of the piston rod of the lifting cylinder 35. The size of the lifting block 36 is adapted to the size of the discharge port 61. Under the drive of the lifting cylinder 35, the lifting block 36 can be inserted into the discharge port 61.

[0058] Reference Figure 4 and Figure 6 A support block 37 is provided on the side of the lifting block 36 away from the lifting cylinder 35. Two buffers 38 are provided between the support block 37 and the lifting block 36. In this embodiment, the buffers 38 are shock-absorbing dampers. When the workpiece falls from the bottom wall of the partition turntable 72, it can land on the surface of the support block 37 and be buffered by the buffers 38, thereby protecting the structural safety of the workpiece.

[0059] Reference Figure 4 and Figure 6 The surface of the loading platform 3 is provided with a booster component 8. The booster component 8 is located on the side of the hidden groove 34 away from the machine body 1. The booster component 8 is used to push the workpiece on the surface of the bearing block 37 into the limiting channel 33. The booster component 8 includes a limiting sleeve 81, a push rod 82, a reset component 83, a sliding groove 84, a pushing protrusion 85, and a connecting rod 86.

[0060] Reference Figure 4 and Figure 6The outer wall of the limiting sleeve 81 is integrally formed with a connecting rod. The other end of the connecting rod is welded to the surface of the loading platform 3. The length direction of the limiting sleeve 81 is consistent with the length direction of the limiting channel 33. The push rod 82 is slidably connected to the inner wall of the limiting sleeve 81. Both ends of the push rod 82 extend out of the limiting sleeve 81. The reset member 83 is disposed between the side wall of the push rod 82 and the inner wall of the limiting sleeve 81. In this embodiment, the reset member 83 is in the form of a spring and a ring plate. The ring plate is integrally formed on the peripheral wall of the push rod 82 located inside the limiting sleeve 81. The spring is sleeved on the peripheral wall of the push rod 82, and one end is connected to the ring plate by adhesive, and the other end is connected to the inner wall of the limiting sleeve 81 by adhesive. When the push rod 82 is dragged, the reset member 83 will accumulate elastic potential energy. After the external force is removed, it will push the push rod 82 to reset.

[0061] Reference Figure 4 and Figure 6 The sliding groove 84 is located on the side of the limiting sleeve 81 away from the lifting block 36. The sliding groove 84 is set in the vertical direction and is connected to the surface of the loading platform 3 by welding. The pushing protrusion 85 is slidably connected in the sliding groove 84. The side wall of the pushing protrusion 85 is integrally formed with a snap-fit ​​block 851. The side wall of the sliding groove 84 is provided with a snap-fit ​​groove 841 for the snap-fit ​​block 851 to pass through and slide. The length direction of the snap-fit ​​groove 841 is consistent with the length direction of the sliding groove 84. The diameter of the pushing protrusion 85 gradually increases from the end closer to the loading platform 3 to the end farther away from the loading platform 3. After the pushing protrusion 85 slides, it will abut against the push rod 82, thereby pushing the push rod 82 to slide towards the bearing block 37, so that the workpiece on the surface of the bearing block 37 enters the limiting channel 33.

[0062] Reference Figure 4 and Figure 6 One end of the connecting rod 86 is hinged to the side wall of the lifting block 36, and the other end is hinged to the side wall of the snap-fit ​​block 851 extending out of the snap-fit ​​groove 841. When the lifting block 36 moves, the pushing protrusion 85 moves vertically with the lifting block 36 due to the driving force of the connecting rod 86 and the restriction of the sliding groove 84. After the bearing block 37 descends, the push rod 82 can push the workpiece on the surface of the bearing block 37. No additional power component is required, saving costs and providing high linkage performance.

[0063] Reference Figure 2 A plurality of push wheels 322 are rotatably connected inside the clearance cavity 321. The push wheels 322 are evenly distributed along the length of the limiting baffle 32. The inner wall of the clearance cavity 321 corresponding to the push wheels 322 is provided with a push port 323 for the push wheels 322 to extend out. The push port 323 is connected to the limiting channel 33, thereby enabling the push wheels 322 to provide thrust to the workpiece in the limiting channel 33 and improve the feeding efficiency.

[0064] Reference Figure 2Both limit baffles 32 have a drive component 324 on their opposite sidewalls. In this embodiment, the drive component 324 is a cylinder. The base of the drive component 324 is welded to the surface of the loading platform 3, and its piston rod is welded to the sidewall of the corresponding limit baffle 32, thereby driving the limit baffle 32 to move. This saves the time spent on manual adjustment, improves the accuracy and efficiency of adjustment, and further improves the overall efficiency of the grinding machine of this application.

[0065] The implementation principle of a straight-through double-end face grinder in Embodiment 2 of this application is as follows: When the workpiece to be ground is block-shaped, the workpiece to be processed is placed in the feeding mechanism 4. After the workpiece passes through the feeding pipe 43, it is unloaded by the unloading component 7, and the bearing block 37 receives it. The push component 8 then transports the workpiece further to the limiting channel 33. Under the action of the transmission mechanism 31 and the pushing mechanism 5, the workpiece will move towards the housing 2, realizing continuous feeding. The machine body 1 can continuously grind the block-shaped workpiece, thereby improving the feeding efficiency and the continuity of work.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
