Description

Technical Field

[0001] The invention relates to the technical field of polishing, and in particular to a polishing device for workpiece processing. Background Art

[0002] A latch is a common hardware accessory, widely used in various devices and scenarios. Some latches are composed of two cylinders with different outer diameters. The small-diameter cylinder (pin rod) is used to insert into the socket for positioning, and the large-diameter cylinder (pin end) is inserted close to the port to block the pin rod from being further inserted and unable to be pulled out. In order to facilitate the insertion and removal of the latch, a pull ring is connected to the pin end.

[0003] Grinding the surface of a latch workpiece is an important process step, which aims to improve the surface quality of the workpiece, remove burrs, flash, knife marks and other defects, and make the latch workpiece smoother; however, this type of latch is inconvenient to grind, and it is difficult to complete the clamping and positioning of the pull ring through a three-jaw chuck. When clamped by a specific fixture, when the pull ring is clamped, the pin rod is prone to eccentricity, and it is difficult to ensure that the center axis remains horizontal, which affects the subsequent grinding. Therefore, a polishing device for workpiece processing is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the background technology and to propose a polishing device for workpiece processing.

[0005] To achieve the above purpose, the technical scheme adopted by the present invention is: a polishing equipment for workpiece processing, comprising a base plate, the upper surface of the base plate is installed with a mounting plate through a driving mechanism, the front surface of the mounting plate is fixedly connected with a fixing seat, one side of the fixing seat is installed with a moving plate through a locking mechanism, the front surface of the fixing seat is fixedly connected with a fixed clamping block, the front end of the moving plate is fixedly connected with a moving clamping block, the upper surface of the fixed clamping block is fixedly connected with a connecting seat, the upper surface of the moving clamping block is fixedly connected with a sleeve seat, one side of the connecting seat is rotated by a reset mechanism and penetrated with a rotating shaft, the side surface of the sleeve seat is penetrated with a sleeve hole, the inner bottom surface of the sleeve hole is provided with a guide groove, one end of the rotating shaft slides through the inner side of the sleeve hole and a guide block is convexly provided on the outer surface, the outer surface of the rotating shaft is fixedly connected with a J-shaped plate, the front and rear edges of the connecting seat are respectively fixedly connected with a supporting plate, and a grinding mechanism is arranged on the upper surface of the base plate and close to the front side of the mounting plate;

[0006] The front and rear two support plates limit the rotation of the J-shaped plate within a range of 180 degrees;

[0007] When the pull ring is clamped between the fixed clamping block and the movable clamping block, the guide block is separated from the inner side of the guide groove.

[0008] Preferably, the driving mechanism comprises a support plate fixedly mounted behind the upper surface of the base plate, a power assembly is fixedly mounted on the upper end of the support plate, and an output end of the power assembly is fixedly mounted to the rear surface of the mounting plate.

[0009] Preferably, the locking mechanism comprises a threaded rod which rotates and passes through one side of the movable plate, one end of the threaded rod is threadedly passed through the side surface of the fixing seat, and the other end of the threaded rod is fixedly connected to a polygonal head.

[0010] Preferably, the reset mechanism includes a terminal rod fixedly connected to one end of the outer surface of the rotating shaft, the front end of the terminal rod is fixedly connected to an arc rod, the rear end of the arc rod is fixedly connected to a limiting head, one side surface of the connecting seat is fixedly connected to a baffle, the arc rod slides through the upper surface of the baffle, and the outer surface of the arc rod is sleeved with a compression spring.

[0011] Preferably, the grinding mechanism includes a fixed frame fixedly installed on the upper surface of the base plate, a cushion frame is fixedly installed on the upper surface of the fixed frame, an L-shaped frame is fixedly installed on the upper surface of the cushion frame by bolts, a docking plate is fixedly connected to one side surface of the L-shaped frame, and a rod grinding piece is provided on one side of the docking plate.

[0012] Preferably, the bolt member includes two mounting columns fixedly mounted on the upper surface of the raised frame, a mounting opening is formed through the upper surface of the L-shaped frame, the mounting columns slide through the inner side of the mounting opening, and a mounting nut is threadedly sleeved on the upper end of the mounting column.

[0013] Preferably, the rod grinding member comprises an inserting column threadedly penetrating the outer surface of the docking plate, and a grinding rod is fixedly connected to the rear end of the inserting column.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention can place the pull ring of the bolt between the fixed clamp block and the movable clamp block, so that the entire bolt can be kept horizontal as much as possible, and then move it upward so that the upper surface of the pin end is flat against the lower surface of the J-shaped plate to complete the positioning. It has the function of quickly positioning the bolt workpiece and ensures that the central axis of the bolt remains horizontal after positioning;

At the same time, the sleeve relatively slides along the surface of the rotating shaft, and the guide block relatively slides along the inner side of the guide groove. When the guide block slides out of the guide groove, the arc rod rotates under the elastic force of the compression spring, so that the J-shaped plate rotates upward to prevent interference with the subsequent grinding rod to grind the surface of the pin rod and the pin end. While the pin is clamped, the J-shaped plate used for reference can automatically rotate and reset, without interfering with the subsequent grinding, and the operation is convenient;

[0017] 3. During the grinding process of the present invention, two grinding rods contact the surface of the pin end and the pin rod respectively. With the driving of the power assembly, the mounting plate rotates, thereby causing the latch pin to rotate, and the grinding rods grind the surface of the latch pin. The grinding process is accurate and convenient, and the connection position between the pin rod and the pin end will not be ground, thereby causing the problem of damage to the overall structure.

[0027] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0028] like Figure 1-Figure 8 The polishing equipment for workpiece processing shown in the figure comprises a base plate 1, a mounting plate 4 is mounted on the upper surface of the base plate 1 through a driving mechanism, a fixed seat 5 is fixedly connected to the front surface of the mounting plate 4, a movable plate 6 is mounted on one side of the fixed seat 5 through a locking mechanism, a fixed clamping block 9 is fixedly connected to the front surface of the fixed seat 5, a movable clamping block 10 is fixedly connected to the front end of the movable plate 6, a connecting seat 11 is fixedly connected to the upper surface of the fixed clamping block 9, a sleeve seat 20 is fixedly connected to the upper surface of the movable clamping block 10, a rotating shaft 12 is penetrated through one side of the connecting seat 11 through a reset mechanism, a sleeve hole 21 is penetrated through the side surface of the sleeve seat 20, and a guide groove 22 is opened on the inner bottom surface of the sleeve hole 21. The specific structure is as follows Figure 6 As shown, one end of the rotating shaft 12 slides through the inner side of the sleeve hole 21 and a guide block 23 is protruded on the outer surface. A J-shaped plate 19 is fixedly connected to the outer surface of the rotating shaft 12. The front and rear edges of the connecting seat 11 are respectively fixedly connected to the supporting plate 18. A grinding mechanism is provided on the upper surface of the bottom plate 1 and near the front side of the mounting plate 4.

[0029] The front and rear two support plates 18 restrict the J-shaped plate 19 from rotating within a range of 180 degrees;

[0030] When the pull ring 35 is clamped between the fixed clamp block 9 and the movable clamp block 10, the guide block 23 is separated from the inner side of the guide groove 22. That is, after clamping, the rotating shaft 12 rotates under the action of the reset mechanism.

[0031] like Figure 1 , Figure 2 As shown, the driving mechanism includes a support plate 2 fixedly mounted on the rear side of the upper surface of the base plate 1, a power assembly 3 is fixedly mounted on the upper end of the support plate 2, and the output end of the power assembly 3 is fixedly mounted on the rear surface of the mounting plate 4. The power assembly 3 includes a motor and a gear box, which is a common prior art, and will not be described in detail. The mounting plate 4 is fixedly mounted on the output end of the gear box by bolts.

[0032] like Figure 5 As shown, the locking mechanism includes a threaded rod 7 that rotates and penetrates one side of the movable plate 6, one end of the threaded rod 7 is threadedly penetrated through the side of the fixed seat 5, and the other end of the threaded rod 7 is fixedly connected to a polygonal head 8. The polygonal head 8 is convenient for rotating the threaded rod 7 with a wrench. When the threaded rod 7 rotates, the movable plate 6 is driven to move in a direction relatively close to the fixed seat 5.

[0033] like Figure 3 , Figure 4As shown, the reset mechanism includes a terminal rod 17 fixedly connected to one end of the outer surface of the rotating shaft 12, the front end of the terminal rod 17 is fixedly connected to the arc rod 14, the rear end of the arc rod 14 is fixedly connected to the limiting head 16, a baffle 13 is fixedly connected to one side surface of the connecting seat 11, the arc rod 14 slides through the upper surface of the baffle 13, and a compression spring 15 is sleeved on the outer surface of the arc rod 14. The design of the limiting head 16 can prevent the compression spring 15 from detaching from the arc rod 14 and falling off.

[0034] like Figure 7 As shown, the grinding mechanism includes a fixed frame 32 fixedly mounted on the upper surface of the base plate 1, a spacer frame 24 is fixedly mounted on the upper surface of the fixed frame 32, an L-shaped frame 25 is fixedly mounted on the upper surface of the spacer frame 24 through bolts, a docking plate 29 is fixedly connected to one side of the L-shaped frame 25, and a rod grinding piece is arranged on one side of the docking plate 29. The spacer frame 24 makes the rod grinding piece at a suitable height so that the surface of the pin can be ground.

[0035] The bolt member includes two mounting posts 27 fixedly mounted on the upper surface of the pad frame 24. A mounting opening 26 is formed through the upper surface of the L-shaped frame 25. The mounting posts 27 slide through the inner side of the mounting opening 26. The upper end of the mounting posts 27 is threadedly sleeved with mounting nuts 28. After the mounting nuts 28 are unscrewed, the mounting posts 27 can be separated from the mounting opening 26, so that the L-shaped frame 25 can be flexibly disassembled and replaced conveniently.

[0036] The rod grinding member includes a plug-in column 30 threadedly penetrating the outer surface of the docking plate 29, and a grinding rod 31 is fixedly connected to the rear end of the plug-in column 30. When the grinding rod 31 is severely worn, the user can remove the plug-in column 30 from the docking plate 29 by rotating the plug-in column 30 for replacement.

[0037] The user rotates the J-shaped plate 19 one hundred and eighty degrees toward the upper front. At this time, the guide block 23 is located on the lower surface of the rotating shaft 12. While pressing the J-shaped plate 19, the threaded rod 7 is rotated to move the movable plate 6 away from the fixed seat 5. At this time, the guide block 23 slides relatively into the inner side of the guide groove 22, and the J-shaped plate 19 is released. Due to the limiting effect of the guide groove 22 on the guide block 23, the J-shaped plate 19 can be prevented from rotating and resetting under the elastic force of the compression spring 15.

[0038] After that, the user places the pull ring 35 between the fixed clamp block 9 and the movable clamp block 10, keeps the entire latch pin as horizontal as possible, and then moves it upward so that the upper surface of the pin end 34 is flat against the lower surface of the J-shaped plate 19, and the positioning is completed. Figure 8As shown, the polygonal head 8 is then rotated to rotate the threaded rod 7, which drives the movable plate 6 to translate and clamp the pull ring 35. At the same time, the sleeve 20 slides relatively along the surface of the rotating shaft 12, and the guide block 23 slides relatively along the inner side of the guide groove 22. When the guide block 23 slides out of the guide groove 22, the arc rod 14 rotates under the elastic force of the compression spring 15, so that the J-shaped plate 19 rotates upward to prevent interference with the subsequent grinding rod 31 in grinding the surfaces of the pin rod 33 and the pin end 34. Therefore, it has the function of rapid positioning, and while positioning and clamping, the J-shaped plate 19 used for reference can automatically rotate and reset without interfering with subsequent grinding.

[0039] During the grinding process, the two grinding rods 31 contact the surfaces of the pin end 34 and the pin rod 33 respectively. As the power assembly 3 is driven, the mounting plate 4 rotates, thereby causing the latch to rotate. The grinding rods 31 grind the surface of the latch. The grinding process is precise and convenient, and the connection position between the pin rod 33 and the pin end 34 will not be ground, thereby causing damage to the overall structure.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
