[0021] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "fixed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0022] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] See also Figures 1 to 9 As shown, the embodiment of the present application discloses a reciprocating double-sided grinder, comprising a frame 1, two grinding discs 2 arranged opposite to each other and a grinding motor group for driving the two grinding discs 2 to rotate are arranged on the rear side of the frame 1, and a grinding channel is formed between the two grinding discs 2; a feeding mechanism, a discharging mechanism and a pressing grinding mechanism are arranged on the front side of the frame 1, preferably, the feeding mechanism, the discharging mechanism and the pressing grinding mechanism are arranged in the left and right directions of the frame 1, wherein the pressing grinding mechanism is arranged between the feeding mechanism and the discharging mechanism, and is used to receive a plurality of workpieces arranged together at the outlet end of the feeding mechanism, and to feed and move them into and out of the grinding channel; in addition, the feeding mechanism comprises a feeding conveyor belt 25, a collecting assembly and The pushing assembly and the collecting assembly are used to arrange the workpieces conveyed one by one on the feed conveyor belt 25 together in a set number, and the pushing assembly is used to push the workpieces arranged together on the collecting assembly as a whole to the pressure grinding mechanism; the discharging mechanism includes the discharging conveyor belt 26, the transfer assembly and the material shifting assembly; when the previous group of workpieces on the pressure grinding mechanism is ground and moved out of the grinding channel, the pushing assembly is used to push the next group on the collecting assembly to the pressure grinding mechanism, and at the same time, the next group of workpieces extrude and push the previous group of workpieces to the transfer assembly, and the material shifting assembly is used to shift the entire row of workpieces on the transfer assembly to the discharging conveyor belt 26 one by one, and then transfer them to the next workstation through the discharging conveyor belt 26.

[0024] In this embodiment, see the attached Figures 3 to 5 The material pressing and grinding mechanism includes a sliding plate 3 which can slide along the front and rear directions of the frame 1, and a support frame is connected to the sliding plate 3, and a material receiving platform 4 for supporting the workpiece is arranged on the support frame, and a positioning baffle 5 is arranged at one end of the material receiving platform 4, and a first material pressing component which can move in the horizontal direction is arranged on the side of the support frame opposite to the positioning baffle 5, and a second material pressing component which can be lifted and lowered in the vertical direction is also arranged on the support frame above the material receiving platform 4, and also includes a driving component connected to the frame 1, and the driving component is used to drive the sliding plate 3 to move forward and backward to drive the workpiece to be fed into and removed from the grinding channel. When several neatly arranged workpieces on the feeding assembly enter the receiving table 4, the first pressure assembly runs horizontally until it is pressed against the side of the workpiece away from the positioning baffle 5, thereby realizing horizontal limitation of the workpieces; then the second pressing assembly moves downward until it is pressed against the upper end surfaces of the workpieces, thereby further realizing vertical limitation of the workpieces; finally, the driving assembly drives the sliding plate 3 to move toward the grinding channel, thereby realizing synchronous grinding of the two end surfaces of the workpieces. After the grinding is completed, the driving assembly continues to drive the sliding plate 3 to move in the opposite direction to realize automatic removal of the workpieces.

[0025] In this embodiment, see the attached Figure 2 and 5The driving assembly includes a driving gear and a rack 6, wherein the rack 6 is connected to the lower end surface of the sliding plate 3 and extends along the sliding direction of the sliding plate 3. In addition, a driving motor (not shown in the figure) is connected to the frame 1, and the driving gear is connected to the output shaft of the driving motor. The driving gear is meshed with the rack 6. The gear drives the rack 6 to move toward and away from the grinding channel through the forward and reverse rotation of the driving motor, thereby realizing the feeding and moving of multiple workpieces. The structure is simple and the drive is stable and reliable.

[0026] In this structure, in order to further ensure the smoothness of the forward and backward movement of the sliding plate 3, two linear slide rails 8 extending along the forward and backward directions are connected to the top plate of the frame 1, and two groups of slider groups are connected to the lower end surface of the sliding plate 3, which are slidably connected to the two linear slide rails 8 respectively.

[0027] In this embodiment, for more details, see the attached Figure 4 The support frame includes a horizontally arranged cross bar 9, the material receiving table 4 is connected to the upper surface of the front end of the cross bar 9, the first pressing assembly includes a first driving cylinder 11, a first actuating rod 12 and a first pressing block 13, the rear end of the cross bar 9 is connected to a vertically arranged fixed plate 10, the first driving cylinder 11 is horizontally connected to the fixed plate 10, the first actuating rod 12 is connected to the free end of the first driving cylinder 11, and the first pressing block 13 is connected to the front end of the first actuating member. When several workpieces are transferred to the material receiving table 4, the first driving cylinder 11 drives the first actuating cylinder to move forward until the first pressing block 13 is pressed against the rear end of the last workpiece to achieve horizontal pressing and limiting of multiple workpieces.

[0028] Similarly, in this embodiment, the second pressing assembly includes a second driving cylinder 14 horizontally arranged on the fixed plate 10, the free end of the second driving cylinder 14 is connected to a second actuating rod 15 moving in the horizontal direction, and a second pressing block 16 which can be lifted vertically is arranged above the material receiving table 4. The second actuating rod 15 is used to drive the second pressing block 16 to move up and down to realize vertical clamping limit and release limit for multiple workpieces; in subsequent operations, unloading can only be realized after the workpieces on the material receiving table 4 are released from the limit in the horizontal and vertical directions.

[0029] See the attached Figure 4The cross bar 9 is connected with two first vertical bars 17 respectively located at the front and rear sides of the material receiving platform 4. The upper ends of the two first vertical bars 17 are provided with first through holes 18. The free end of the second actuating rod 15 is slidably penetrated in the two first through holes 18. The upper ends of the two first vertical bars 17 and below the first through holes 18 are provided with vertically extending second through holes 19. The two second through holes 19 are connected with vertically movable active bars 20. Two sets of linkage plates 21 are hinged on the active bars 20. The upper ends of the two sets of linkage plates 21 are hinged to the second actuating rods 15, respectively. The free end of the two linkage plates 21 are inclined toward one side of the fixed plate 10 to form a parallelogram driving structure. The second pressure block 16 is connected to the lower end surface of the movable rod 20. When the second actuating rod 15 moves toward the direction close to the material receiving platform 4, the movable rod 20 moves downward to drive the second pressure block 16 to be pressed against the upper surface of the workpiece to achieve vertical clamping and limiting; or moves upward to drive the second pressure block 16 away from the upper surface of the workpiece; when the second actuating rod 15 moves toward the direction away from the material receiving platform 4, the movable rod 20 moves upward to reset and release the vertical limit on multiple workpieces.

[0030] On the other hand, in the above structure, a third through hole 22 is further provided at the lower end of the first vertical rod 17 close to the side of the fixed plate 10, and the free end of the first actuating rod 12 is slidably penetrated in the third through hole 22, thereby realizing the guide limitation for the horizontal balance movement of the first actuating rod 12 and ensuring the stability of its horizontal movement.

[0031] In this embodiment, the length direction span of the sliding plate 3 is relatively large, that is, the lengths of the first actuating rod 12 and the second brake rod are relatively large. In order to further ensure the stability of the movement of the two actuating rods, a second vertical rod 23 is additionally provided between the first vertical rod 17 on the side close to the fixed plate 10 and the fixed plate 10 on the cross bar 9, and a fourth through hole 24 is provided on the second vertical direction for the second actuating rod 15 and the first actuating rod 12 to slide in the horizontal direction, respectively. See the attached Figure 2 shown.

[0032] In addition, in this embodiment, the first pressing block 13 and the second pressing block 16 are both detachably connected with rubber pads on one side close to the workpiece. The rubber material with a relatively soft hardness directly contacts the surface of the workpiece, which can avoid damage to the outer surface of the workpiece.

[0033] The most important thing is that in this embodiment, when positioning the workpiece, the workpiece is clamped and limited in both the horizontal and vertical directions, and the horizontal bottom surface and vertical side surface of the workpiece have abutment references, thereby ensuring that the workpiece limit is stable and reliable, so that the vertical accuracy of the workpiece after grinding is much higher than the traditional straight-through double-end face grinding method.

[0034] On the other hand, in this embodiment, see the attached Figure 6The material collection assembly includes a first push cylinder 27 and a collection plate 28 perpendicular to the feed conveyor belt 25, and one end of the collection plate 28 is connected to the discharge end of the feed conveyor belt 25, and the other end of the collection plate 28 is provided with a positioning assembly, the first push cylinder 27 is located on the frame 1 and close to the discharge end of the feed conveyor belt 25, and the piston rod of the first push cylinder 27 is connected with a first push plate 29, which is used to push the workpieces at the discharge end of the feed conveyor belt 25 one by one onto the collection plate 28 along the length direction of the collection plate 28. In this structure, more specifically, a sensor is also provided at a position corresponding to the first push plate 29 on the frame 1, and when the sensor detects the workpiece model, the first push cylinder 27 is opened and operated to ensure the automatic control of the entire workpiece transmission process.

[0035] More specifically, the positioning assembly in the above structure includes a positioning block 30 that can slide along the length direction of the collecting plate 28 and a positioning drive member 31 for driving the positioning block 30 to always have a tendency to move toward the side of the first push plate 29, and in the initial state, the positioning block 30 is close to the discharge end of the feed conveyor belt 25, and when the workpieces move one by one onto the collecting plate 28, the positioning block 30 moves backward synchronously.

[0036] In this embodiment, preferably, the positioning drive member 31 is a rodless cylinder, one end of the positioning block 30 is connected to the slider of the rodless cylinder, and in the initial state, the positioning block 30 is located at the front end of the collecting plate 28. As the workpieces on the feed conveyor belt 25 are pushed onto the collecting plate 28 one by one, the workpiece at the rear end pushes the positioning block 30 and moves slowly backwards, ensuring that the workpieces can be clamped and limited in the length direction of the collecting plate 28, avoiding overturning of multiple workpieces after being pushed onto the collecting plate 28, especially thinner workpieces, which have poor stability. After adding the positioning component to this structure, it is ensured that multiple workpieces are always clamped and limited in the process of being pushed onto the collecting plate 28, and the stability is high.

[0037] In addition, the pushing assembly in the above structure includes a second pushing cylinder 46 extending along the movement direction of the feed conveyor belt 25, and a second pushing plate 47 is connected to the piston rod of the second pushing cylinder 46. The lower end surface of the second pushing plate 47 is flush with the upper end surface of the collecting plate 28. When a set number of workpieces are arranged on the collecting plate 28, the second pushing cylinder 46 drives the second pushing plate 47 to push the entire row of workpieces on the collecting plate 28 onto the material receiving table 4, and then the first pressing assembly and the second pressing assembly realize the clamping and limiting of the workpieces.

[0038] On the other hand, in this embodiment, see the attached Figure 7The transfer assembly includes a transfer bracket 32 ​​connected to the frame 1, on which a transfer plate 33, a material shifting plate 34 and a material shifting drive assembly are provided. A material baffle plate 35 is provided at one end of the transfer plate 33 close to the discharge conveyor belt 26. One end of the material shifting plate 34 is connected to the drive assembly, and the other end can be slidably engaged with the upper surface of the other end of the transfer plate 33, so as to push the workpiece on the transfer plate 33 toward one end of the discharge conveyor belt 26; the lower end surface of the material baffle plate 35 is higher than the upper end surface of the transfer plate 33 to form a material shifting channel, and the height of the material shifting channel is less than the thickness of the workpiece. One end of the material shifting rod 36 of the material shifting assembly can move through the material shifting channel, so as to shift the workpieces one by one into the discharge conveyor belt 26. The material shifting channel with a special height in this structure is set to facilitate the material shifting rod 36 to shift one workpiece to the discharge conveyor belt 26 each time, but at the same time ensure that both ends of the entire row of workpieces are pressed and limited.

[0039] In this embodiment, see the attached Figure 7 The material shifting drive assembly includes a conveyor belt 48 horizontally arranged on the transfer bracket 32 ​​and a material shifting motor for driving the conveyor belt 48 to operate. One end of the material shifting plate 34 is connected to the conveyor belt 48, and the other end extends to the top of the transfer plate 33. When the entire row of workpieces that have been ground on the pressing and grinding mechanism are transferred to the transfer plate 33, the material shifting motor drives the material shifting plate 34 to press and limit at the rear end of the entire row of workpieces until the front end of the entire row of workpieces abuts against the baffle plate 35; when the material shifting assembly shifts the front end of the entire row of workpieces to the discharge conveyor belt 26, the material shifting motor continues to drive the conveyor belt 48 to drive the material shifting plate 34 to push the workpiece forward until the entire row of workpieces has been fully shifted, and the material shifting plate 34 resets to its initial position to wait for the next group of workpieces to be transferred to the intermediate plate.

[0040] In some other embodiments, the material moving assembly may also adopt mechanisms such as a pneumatic cylinder, an oil cylinder or a linear motor, which can be used to drive the material moving plate 34 to move back and forth along the transfer plate 33.

[0041] More specifically, in the above structure, see the attached Figure 8 , 9The material-dispensing assembly includes a fixed base plate 37, a first slide plate 38, a second slide plate 39 and a material-dispensing motor 40. The fixed base plate 37 is fixedly connected to the transfer bracket 32 ​​in the horizontal direction. The first slide plate 38 is slidably connected to the upper end surface of the fixed base plate 37 by a linear guide rail. The second slide plate 39 is slidably connected to the upper end surface of the first slide plate 38 by a linear guide rail in the front-to-back direction. The material-dispensing rod 36 is connected to the second slide plate 39 extending in the front-to-back direction; an arc through hole 41 extending in the left-to-right direction is provided on the sliding plate 3 of the fixed plate 10, and a cam 42 is slidably mounted in the arc through hole 41. A connecting plate 43 is provided at the upper end of the cam 42, and one end of the connecting plate 43 is connected to a vertically arranged roller shaft 44. An elongated through hole 45 extending in the front-to-back direction is provided on the second slide plate 39, and the roller shaft 44 is fitted in the elongated through hole 45. The material-dispensing motor 40 is vertically connected to the lower end of the fixed base plate 37, and the output shaft of the material-dispensing motor 40 is connected to the lower end of the cam 42. When the material-moving motor 40 is running, with the cooperation of the cam 42, the roller 44, the arc-shaped through hole 41 and the elongated through hole 45, the material-moving plate can move back and forth in the left and right and front and back directions to realize the transfer of workpieces on the transfer plate 33 One by one is sent to the discharge conveyor belt 26. The entire material-moving process is automated without the need for manual intervention, thereby improving the work efficiency of the entire assembly line.

[0042] In some other embodiments, the material shifting assembly may also include a conveyor chain or conveyor belt that moves in the same direction as the discharge conveyor belt 26, and a plurality of material shifting rods 36 perpendicular to the conveyor chain or conveyor belt are connected to the conveyor chain or conveyor belt at a set distance, and the free end of each material shifting rod 36 can slide through the material shifting channel to push the workpieces on the transfer plate 33 one by one to the discharge conveyor belt 26, and each time a workpiece is pushed, the material moving plate 34 will drive the entire row of workpieces to move forward by the position of one workpiece to achieve continuous pushing of workpieces.

[0043] In the above connection, more specifically, the transfer plate 33 is slidably connected to the transfer bracket 32 ​​in the left and right directions, and the transfer bracket 32 ​​is also provided with a material receiving drive cylinder, and the piston rod of the material receiving drive cylinder is connected to the left end of the transfer plate 33. Figure 8Two limit blocks 49 are arranged on the horizontal support plate of the transfer bracket 32, and a guide slot is formed between the two limit blocks. The lower end of the transfer plate 33 is connected to a guide slider 50 that slides with the guide slot. Preferably, the two sides of the guide slider 50 are inclined surfaces, and the two side walls of the guide slot are also corresponding inclined surfaces, so as to ensure that the transfer plate 33 is more stable and reliable when sliding left and right. In this structure, when a whole row of workpieces on the press grinding mechanism needs to be transferred to the transfer plate 33, the material receiving drive cylinder drives the transfer plate 33 to move in advance to align with the material receiving table 4, so as to ensure that the whole row of workpieces on the material receiving table 4 can be transferred to the transfer plate 33 in an orderly manner.
