Description

Technical Field

[0001] The present invention relates to the technical field of bar processing, and particularly relates to a grinding bar processing device. Background Art

[0002] A grinding bar processing device is a special machine tool that removes a small amount of material from the outer surface of a bar-shaped material through the relative movement between a rotating grinding wheel and a workpiece to achieve dimensional accuracy and surface quality control. In the current industry, the centerless grinding method is commonly used. Through the coordinated action of a guide wheel, a support plate, and a grinding wheel, the bar is continuously ground in a state of no center clamping: during processing, the rotating guide wheel drives the bar to rotate around its own axis and feed axially, the support plate provides radial support, and the grinding wheel grinds the outer circle of the bar.

[0003] However, the above bar grinding process has the following problems: when the grinding wheel grinds the head and tail ends of the bar, the bar between the grinding wheel and the guide wheel lacks stable support and limitation, and is prone to vibration during grinding, resulting in a tapered collapse or wavy texture at the end, and at the same time increasing the risk of chipping; secondly, during the continuous forward feeding process of the bar, the friction force with the support plate is unstable, resulting in an unstable forward speed of the bar. This uneven movement will cause the grinding amount of the grinding wheel at different positions to be inconsistent, resulting in uneven diameters of the processed bars and obvious defects on the surface.

[0004] Therefore, the damage of the bar caused by vibration during end grinding, as well as the dimensional fluctuations and surface defects caused by unstable friction force during the feeding process, are technical problems that need to be solved by those skilled in the art.

[0010] As a preferred solution, the driving part includes a sliding plate. A sliding plate with a U-shaped structure is slidably installed on the upper end of the supporting plate. A first guiding groove corresponding to the left positioning block one by one is formed in the left longitudinal section of the sliding plate.

[0012] As a preferred solution, both the first guiding groove and the second guiding groove are composed of a horizontal section and an inclined section connected to one end of the horizontal section close to the middle of the sliding plate.

In addition, the radial clamping of the positioning block synergistically suppresses the end vibration, and the dynamic downward pressure of the pressing block and the support seat form a three-point rolling support, so that the rod is always in a coordinated control state of axial constraint, radial limit and uniform feeding during the rotation and translation process, improving the machining accuracy and surface quality as a whole, and avoiding defects such as tapered collapse, wavy lines and uneven dimensions.

[0017] Second, the present invention clamps the rod by the positioning block, and forms a synchronous rolling limit at the front and rear ends with the pressing block and the support seat; combined with the negative pressure adsorption of the suction cup end face and the radial clamping of the clamping block, a three-dimensional rigid system of axial fixation, radial constraint and vertical support is realized; and the pressing block presses down following the grinding process, enhancing the anti-vibration performance of the grinding area, offsetting the deformation of the rod caused by the grinding wheel cutting force, and ensuring that the grinding surface of the rod is flat without collapse and the texture is uniform.

[0018] Third, the present invention ensures uniform pushing through the driving part, reduces the fluctuation of the friction resistance by rolling contact, and the inclined groove and the guide post cooperate to balance the axial movement resistance through the progressive pressure of the clamping block combined with the dynamic adsorption compensation of the suction cup, so that the grinding amount of the grinding wheel is uniform, avoiding diameter deviation, surface scratches and periodic defects caused by unstable speed, thereby ensuring the consistency of machining.

Detailed implementation manners

[0028] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] As Figure 1 and Figure 3 shown, a grinding rod processing device includes a grinding device 1 and equipment frames 20 arranged on its left and right sides; a bottom plate 21 is fixedly installed on the equipment frame 20, and a reinforcement mechanism 2 is arranged on the bottom plate 21.

[0030] As Figure 1 and Figure 2 shown, the grinding device 1 includes a workbench 10, on which a grinding wheel 11 and a guide wheel 12 are rotatably arranged front and back, and a support base 13 is fixedly installed between the grinding wheel 11 and the guide wheel 12. The grinding device 1 is a publicly known technology, and its specific structure is not the innovation point of the present invention, so no more details will be described here.

[0031] As Figures 1 to 6As shown, the reinforcement mechanism 2 includes a moving frame 22 which is slidably mounted on a bottom plate 21, a suction cup 23 is rotatably mounted on the moving frame 22 and a piston 230 is slidably mounted inside the suction cup 23, two clamping blocks 24 and two driving plates 25 with inclined grooves 250 are also slidably mounted on the moving frame 22, and a guide column 251 which slides through the corresponding inclined grooves 250 is provided on the clamping block 24; a fixed frame 26 is provided between the two bottom plates 21, a pressure block 27 located directly above the support seat 13 is slidably mounted on the fixed frame 26, two front-to-back symmetrical positioning blocks 28 are slidably mounted on the side of the bottom plate 21 close to the workbench 10, and a driving part 4 for driving the positioning block 28 to move forward and backward and the pressure block 27 to rise and fall in sequence is provided on the fixed frame 26.

[0032] like Figure 1 and Figure 4 As shown, the movable frame 22 includes a movable seat 220 and a connecting plate 221, a roller feeding piece 6 is installed in the middle of the bottom plate 21, and two movable seats 220 symmetrically mounted front and back about the roller feeding piece 6 are slidably mounted on the upper end of the bottom plate 21, and a connecting plate 221 is fixedly mounted on one end of the front and back symmetrical movable seats 220 close to the workbench 10, and a driving plate 25 is slidably mounted on the upper end of the connecting plate 221, and the two inclined grooves 250 on the two driving plates 25 form an eight-shaped structure with the small diameter end facing the workbench 10.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, the lower end of the base plate 21 is rotatably mounted with two left-right symmetrical rotating shafts 30 through an axle seat, and synchronous wheels corresponding to the moving seat 220 are fixedly mounted at both the front and rear ends of the rotating shaft 30, and a synchronous belt 31 is connected for transmission between the two synchronous wheels opposite to each other on the left and right, and rectangular grooves corresponding to the synchronous belts 31 are opened on the base plate 21, and a connecting plate 32 is fixedly mounted on the synchronous belt 31, and the connecting plate 32 is fixedly connected to the corresponding moving seat 220 after sliding through the rectangular groove.

[0034] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the surfaces where the positioning block 28, the pressure block 27, the support seat 13 and the clamping block 24 contact the rod material are all rolling friction. The positioning block 28, the pressure block 27, the support seat 13 and the clamping block 24 can be supported by the rod material through balls (the balls on the pressure block 27 are not shown in the figure), so as to reduce the friction force of the positioning block 28, the pressure block 27, the support seat 13 and the clamping block 24 on the rod material, thereby ensuring that the rod material can rotate and translate normally, and further ensuring the normal grinding.

[0035] like Figure 1 , Figure 2 and Figure 3As shown, the roller feeder 6 includes a support frame 60. The support frame 60 is provided at the upper end of the base plate 21. A plurality of guiding assemblies are evenly and rotatably installed on the support frame 60 from left to right. Each guiding assembly consists of two rollers 61 that are distributed staggeredly front and back. The axes of the rollers 61 are horizontally parallel to the axis of the bar stock. During the process of the bar stock rotating to receive circumferential grinding by the cooperation of the grinding wheel 11 and the guide wheel 12 that rotate synchronously but in opposite directions, the two rollers 61 that are distributed staggeredly front and back rotate synchronously and in opposite directions, assisting the bar stock to rotate stably and continuously. At the same time, the auxiliary wheels can also limit the bar stock front and back. It should be noted that the plurality of rollers 61 between the two support plates can be synchronously rotated through the cooperation of existing driving and linkage components, and the rotation speed is synchronized with the grinding wheel 11 and the guide wheel 12.

[0036] As Figures 1 to 6 shown, during specific operation, an operator places the bar stock to be ground on the left roller feeder 6, makes the bar stock contact the rollers 61, and fits the left end of the bar stock with the left suction cup 23. Then, the left clamping block 24 clamps the left end of the bar stock, and at the same time drives the piston 230 to move, so that the suction cup 23 adsorbs and supports the left end face of the bar stock. Then, an external motor (not shown in the figure) installed at the lower end of the base plate 21 drives the rotating shaft 30 to rotate. The rotating shaft 30 drives the synchronous belt 31 to rotate through the synchronous pulley. The synchronous belt 31 drives the moving frame 22 to move to the right through the connecting plate 32. The moving frame 22 drives the left clamping block 24 and the limited bar stock to pass through the two left positioning blocks 28 from left to right. The two left positioning blocks 28 are driven by the driving part 4 to move closer to each other and extrude and limit the bar stock through the balls.

[0037] As the moving frame 22 moves, the bar stock moves between the grinding wheel 11 and the guide wheel 12 that rotate synchronously but in opposite directions to receive circumferential grinding. The ground part of the bar stock will contact the support seat 13. Then, the driving part 4 pushes the pressing block 27 to move downward, while the left positioning block 28 keeps limiting the bar stock. Thus, the bar stock passes through the grinding device 1 in a state of being limited by the support seat 13 and the pressing block 27, avoiding the situation of bar stock shaking during the grinding of the bar stock end, which affects the processing quality of the bar stock.

[0038] After the end of the bar stock passes through the grinding area and penetrates through the two positioning blocks 28 on the right side, the driving part 4 drives the positioning block 28 on the right side to extrude and limit the bar stock. At the same time, the right end of the bar stock abuts against the suction cup 23 on the right side. Then, the clamping block 24 on the right side clamps the right end of the bar stock, and the suction cup 23 on the right side adsorbs the right end face of the bar stock and pulls the bar stock to continue moving to the right until the bar stock penetrates through the grinding device 1 to complete the processing. It should be noted that the clamping and limiting forces exerted by the positioning block 28 and the clamping block 24 on the bar stock, as well as the clamping and limiting forces exerted by the pressing block 27 and the support seat 13 in cooperation on the bar stock, are adjusted and tested multiple times before the equipment starts working for the first time to ensure that the clamping and limiting forces are appropriate and avoid affecting the feeding and rotation of the bar stock. In addition, existing components such as pressure sensors can also be used to control the clamping and limiting forces in real time.

[0039] As Figure 1 , Figure 3 , Figure 4 and Figure 5 shown, two support rods are symmetrically installed at the front and rear ends of the end of the connecting plate 221 away from the workbench 10. A push-pull plate 50 is slidably installed between the two support rods. The suction cup 23 is rotatably installed in the middle of the connecting plate 221. One end of the piston 230 close to the push-pull plate 50 is coaxially installed with a push rod 51 and is also eccentrically installed with a limiting rod 52 that slidably penetrates through the suction cup 23. The limiting rod 52 synchronizes the rotation of the piston 230 and the suction cup 23, preventing relative rotation between the piston 230 and the suction cup 23, which affects the sealing performance between the piston 230 and the inner wall of the suction cup 23, and further affects the adsorption force of the suction cup 23 on the bar stock; the push rod 51 movably penetrates through the suction cup 23 and then rotatably penetrates through the push-pull plate 50. The lower end of the driving plate 25 is fixedly connected to the upper end of the push-pull plate 50.

[0040] As Figure 4 and Figure 5 shown, the ends of the support rods away from the push-pull plate 50 are fixedly installed with a fixing plate 53 together. One end of the fixing plate 53 away from the push-pull plate 50 is fixedly installed with a first cylinder 54. The telescopic section of the first cylinder 54 slidably penetrates through the fixing plate 53 and is fixedly connected to the push-pull plate 50.

[0041] As Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, during specific operation, the first cylinder 54 pulls the push-pull plate 50 to move towards the fixed plate 53. The push-pull plate 50 drives the piston 230 to move through the push-pull rod 51. The piston 230 moves to suck the air between the suction cup 23 and the bar stock, so that the suction cup 23 adsorbs the end face of the bar stock. At the same time, the push-pull plate 50 drives the driving plate 25 to move. The driving plate 25 drives the corresponding clamping block 24 to extrude and limit the bar stock through the cooperation of the guide post 251 and the inclined groove 250. Then the synchronous belt 31 drives the moving frame 22 to move through the connecting plate 32. The moving frame 22 drives the limited bar stock to move through between the two positioning blocks 28 on the left, pass through the grinding device 1, and then pass through the two positioning blocks 28 on the right. After that, the right clamping block 24 clamps the right end of the bar stock, and at the same time, the right suction cup 23 adsorbs the right end face of the bar stock.

[0042] Subsequently, the two moving frames 22 on the left and right move to the right simultaneously. Until the left moving frame 22 moves in place, the left first cylinder 54 pushes the push-pull plate 50 to move towards the corresponding connecting plate 221. The push-pull plate 50 pushes the piston 230 to move to the right through the push-pull rod 51. The internal high pressure will force the gas to be discharged outward through the port to release the adsorption of the left suction cup 23 on the bar stock. At the same time, through the cooperation of the guide post 251 and the inclined groove 250, the corresponding clamping blocks 24 move away from each other to release the limit on the bar stock, while the clamping block 24 and the suction cup 23 on the right maintain the limit on the bar stock and pull the bar stock through the grinding device 1 to complete the processing.

[0043] As Figure 1 and Figure 6 As shown, the fixing frame 26 includes a bracket 260 and a supporting plate 261. Brackets 260 are fixedly installed on both bottom plates 21. The upper ends of the brackets 260 are fixedly installed with a supporting plate 261 together. Two slide bars are symmetrically arranged on the left and right on the supporting plate 261. The lower ends of the two slide bars slide through the supporting plate 261 and are fixedly installed with a pressing block 27 together. The upper ends of the two slide bars are fixedly installed with a rectangular plate 270 together.

[0044] As Figure 1 and Figure 6 As shown, the driving part 4 includes a sliding plate 40. The upper end of the supporting plate 261 is slidably installed with a sliding plate 40 in a U-shaped structure. The left longitudinal section of the sliding plate 40 is provided with a first guiding groove 41 corresponding to the left positioning block 28 one by one. The upper end of the left positioning block 28 is fixedly installed with a first roller 42 that slides through the first guiding groove 41. The right longitudinal section of the sliding plate 40 is provided with a second guiding groove 43 corresponding to the right positioning block 28 one by one. The upper end of the right positioning block 28 is fixedly installed with a second roller 44 that slides through the second guiding groove 43. The rectangular plate 270 is provided with a third guiding groove 45. The sliding plate 40 is installed with a third roller 46 that slides through the third guiding groove 45. The upper end of the supporting plate 261 is installed with a second cylinder whose telescopic section is fixedly connected to the sliding plate 40.

[0045] As Figure 6 shown, the first guiding groove 41 and the second guiding groove 43 are both composed of a horizontal section and an inclined section connected to one end of the horizontal section near the middle of the sliding plate 40. The inclined sections of the two first guiding grooves 41 are inclined in the direction away from each other, and the inclined sections of the two second guiding grooves 43 are inclined in the direction close to each other. The third guiding groove 45 is composed of an inclined section inclined upward from the right end and a horizontal section connected to both left and right ends of the inclined section.

[0046] As Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown, specifically during operation, in the initial state, the first roller 42 is located at the end of the inclined section of the first guiding groove 41, while the second roller 44 is located in the horizontal section of the second guiding groove 43, and the third roller 46 is located in the lower horizontal section of the third guiding groove 45. After the bar stock passes through the two positioning blocks 28 on the left side, the second air cylinder pulls the sliding plate 40 to move to the right. Under the cooperation of the inclined section of the first guiding groove 41 and the first roller 42, the two positioning blocks 28 on the left side move closer to each other to squeeze and limit the bar stock. At this time, the third roller 46 is located at the connection between the inclined section and the lower horizontal section of the third guiding groove 45, and the second roller 44 is located in the horizontal section of the second guiding groove 43.

[0047] After the bar stock moves between the grinding wheel 11 and the guide wheel 12 and is ground and fits with the support seat 13, the sliding plate 40 continues to move to the right at this time. The sliding plate 40 then makes the rectangular plate 270 move downward through the cooperation of the inclined section of the third guiding groove 45 and the third roller 46. The rectangular plate 270 then pushes the pressing block 27 downward through the sliding rod to squeeze the bar stock to fit with the support seat 13, improving the stability of the end of the bar stock during the grinding process. At this time, the first roller 42 is located in the horizontal section of the first guiding groove 41, the second roller 44 is located at the connection between the horizontal section and the inclined section of the second guiding groove 43, and the third roller 46 is located at the connection between the upper horizontal section and the inclined section of the third guiding groove 45.

[0048] After the right end of the bar stock passes through the grinding device 1 and passes through the two positioning blocks 28 on the right side, the sliding plate 40 continues to move to the right. The sliding plate 40 then drives the two positioning blocks 28 on the right side to move towards each other through the cooperation of the second roller 44 and the second guiding groove 43 to squeeze and limit the bar stock. The suction cup 23 on the right side then fits with the right end face of the bar stock and adsorbs and supports it. At the same time, the clamping block 24 on the right side clamps and limits the bar stock.
