Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical manufacturing, and in particular relates to a processing tool and a method for processing a support seat. Background Art

[0002] In the field of mechanical processing, the support seat is an important structural component, and the processing accuracy of the support seat directly affects the assembly quality and performance. Figure 1 The figure shows a support base with supporting legs, wherein the end face of the support base and the bottom end faces of the two supporting legs are subjected to strict processing requirements.

[0003] The existing conventional processing methods still have the following shortcomings:

[0004] 1. Due to the thin structure of the support legs, vibration is easily generated during conventional processing, resulting in deformation of the workpiece after processing, causing the bottom surface of the support legs to be non-parallel to the end surface of the support seat, seriously affecting the product accuracy;

[0005] 2. The existing processing method requires the end face of the support seat and the bottom face of the support leg to be clamped and processed separately, which is not only inefficient but also has large repeat positioning errors. Although some improved fixtures have achieved single-clamping double-sided processing through a rotating mechanism, these solutions often require the establishment of independent clamping power and rotation power systems, such as the dual-axis motor clamping and hydraulic pump rotation solution shown in the patent with publication number CN119238152B. This design not only increases the equipment cost and structural complexity, but also makes the operation process cumbersome, which is not conducive to improving production efficiency.

[0012] Furthermore, the clamping component includes a shell, and the end of the drive shaft away from the drive motor extends into the shell. Two symmetrical limit rods are provided on the shell, and an annular groove is opened on the side wall of the support rod. The end of the limit rod away from the shell is slidably connected in the annular groove.

[0013] Furthermore, a plurality of receiving grooves are provided on the side wall of the shell, a clamping plate is provided in the receiving groove, a rubber pad is provided on the clamping plate, a movable rod is fixed on the clamping plate, the movable rod is slidably fitted with the shell, and the movable rods on the same side of the length direction of the shell are connected by a connecting rod.

[0014] Furthermore, an annular plate is fixed at one end of the drive shaft in the shell, two arc-shaped grooves are provided on the annular plate, a positioning pin is provided on the connecting rod, the positioning pin is slidably connected in the arc-shaped groove, and when the annular plate rotates °, the positioning pin slides from one end of the arc-shaped groove to the other end of the arc-shaped groove.

[0040] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0041] like Figures 1-8 As shown, a processing tooling and method for a support seat include a base 1 and a support rod 2. A support frame 11 is fixed to the base 1 by screws. A grinding wheel 12 is provided on the top of the support frame 11. The support rod 2 is arranged above the base 1. A clamping assembly for fixing a workpiece is provided on the support rod 2. The base 1 serves as the basic structure for supporting the tooling body and can be formed by welding cast iron or steel plates. Mounting holes are provided on the base 1 for fixing the support frame 2, and the clamping assembly is used to clamp and fix the workpiece.

[0042] A moving assembly is provided between the support rod 2 and the base 1. The moving assembly includes a first electric slide rail 31 fixed to the upper surface of the base 1 by screws. A first slide seat 32 is slidably fitted on the first electric slide rail 31. A second electric slide rail 33 is fixed to the first slide seat 32 by screws. A second slide seat 34 is slidably fitted on the second electric slide rail 33. The support rod 2 is fixed to the upper surface of the second slide seat 34 by screws.

[0043] Specifically, the first slide rail 31 and the second slide rail 33 are perpendicular to each other, and the first slide rail 31 is arranged along the length direction of the base 1. When the workpiece is fixed by the clamping assembly, the workpiece is moved to a suitable grinding position by the second slide rail 33, and then the workpiece is fed by moving the first slide rail 31 to start the grinding work.

[0044] The clamping assembly includes a clamping power component and a clamping component. The clamping power component is fixed to the drive motor 41 on the support rod 2 and the drive shaft 42 rotatably connected to the support rod 2. The output shaft of the drive motor 41 is connected to the drive shaft 42 through a coupling. The clamping component is arranged at the end of the drive shaft 42 away from the drive motor 41. Specifically, the drive motor 41 is fixed to the side of the support rod, and its output shaft is coaxially connected to the horizontally arranged drive shaft 42 through a coupling.

[0045] The clamping component includes a housing 5. The end of the drive shaft 42 away from the drive motor 41 extends into the housing 5. The housing 5 is provided with two symmetrical limit rods 51. An annular groove 21 is formed on the side wall of the support rod 2. The end of the limit rod 51 away from the housing 5 is slidably connected to the annular groove 21.

[0046] Specifically, the shell 5 is composed of two rectangular frames that are detachably fixedly connected by screws, which reduces the difficulty of processing and producing the shell 5 itself and facilitates subsequent maintenance of the components inside the shell 5. A through hole is opened on the side wall of the shell 5, and the drive shaft 42 extends into the shell 5 through the through hole. The drive shaft 42 is loosely matched with the through hole, and the two limit rods 51 serve to support the shell 5. An annular limit groove is opened on the side wall of the annular slide 21, and a limit ring is provided on the limit rod 51. The limit ring is slidably connected in the annular limit groove.

[0047] The side wall of the housing 5 is provided with a plurality of receiving grooves 52, each of which is provided with a clamping plate 53, which is provided with a rubber pad 531. A movable rod 54 is fixed to the clamping plate 53, and the movable rod 54 is slidably engaged with the housing 5. The movable rods 54 on the same side of the length direction of the housing 5 are connected by a connecting rod 55;

[0048] Specifically, the rubber pad 531 can increase the friction between the clamping assembly and the workpiece, making the workpiece clamped more stable. In addition, the rubber pad 531 can compensate for the unevenness of the workpiece surface through elastic deformation, thereby improving the processing accuracy.

[0049] An annular plate 421 is fixed to one end of the drive shaft 42 within the housing 5. The annular plate 421 is provided with two arcuate grooves 422. A positioning pin 551 is provided on the connecting rod 55. The positioning pin 551 is slidably connected to the arcuate groove 422. When the annular plate 421 rotates 180 degrees, the positioning pin 551 slides from one end of the arcuate groove 422 to the other end of the arcuate groove 422.

[0050] Specifically, when clamping the workpiece, the workpiece is placed on the shell 5, and the driving motor 41 rotates 180° clockwise. The driving motor 41 drives the driving shaft 42 to rotate synchronously, thereby driving the annular plate 421 to rotate 180°, so that the positioning pin 551 moves from the end of the arc groove 422 close to the center of the annular plate 421 to the end away from the center of the circle, and under the restriction of the shell 5, the connecting rod 55 moves toward the outside of the shell, thereby driving the clamping plate 53 to move outward to clamp the workpiece. The clamping method is simple and easy to operate, and the clamping plate 53, movable rod 54, connecting rod 55 and annular plate 421 cooperate to form a temporary support structure to support the workpiece, increase the rigidity of the workpiece during processing, and effectively reduce vibration during processing, thereby improving processing accuracy.

[0051] Two pin holes 22 are defined at the bottom of the annular chute 21. A limit pin 23 is slidably connected to the pin holes 22. Specifically, a limit groove is defined on the side wall of the pin hole 22. A limit block adapted to the limit groove is provided on the side wall of the limit pin 23. The limit block is slidably connected to the limit groove. A spring 231 is sleeved on the bottom of the limit pin 23. The end of the limit pin 23 is a wedge-shaped surface. A limit hole 511 adapted to the limit pin 23 is defined on the limit rod 51.

[0052] Specifically, after one surface of the workpiece is machined, the workpiece is still clamped by the clamping assembly, and the positioning pin 551 is in the arc groove 422 at one end away from the annular plate 421. At this time, the driving motor 41 rotates 180° clockwise again, and the side wall of the arc groove 422 pushes the two positioning pins 551 to make the shell 5 rotate synchronously around the central axis of the driving shaft 42. The limiting rod 51 on the shell 5 rotates synchronously and squeezes the limiting pin 23 downward. After the driving shaft 42 rotates 180°, the two limiting rods 51 stay in the position of the limiting pin 23 again. 1 Under the action of the elastic force, the limit pin 23 is inserted into the limit hole 511 to fix the shell, thereby realizing the flipping of the workpiece. When both sides of the workpiece are processed, the drive motor 41 rotates 180° counterclockwise, the clamping assembly releases the fixation of the workpiece, the polished workpiece is removed, and the polishing work is completed. The present invention realizes the completion of two-side processing in one clamping without adding an additional power source, thereby reducing equipment cost, simplifying equipment structure, and improving production efficiency. In addition, it avoids positioning errors caused by multiple clamping and further improves processing accuracy.

[0053] like Figure 9 As shown, the present invention also provides a method for processing tooling applied to the above-mentioned support seat, comprising the following steps:

[0054] S1, sleeve the workpiece onto the outside of the housing 5;

[0055] S2, drive motor 41 to rotate 180° clockwise to clamp the workpiece;

[0056] S3, start the second electric slide 33 to move the workpiece to a suitable grinding position, and start grinding by feeding the workpiece through the first electric slide 31;

[0057] S4, repeat S2 to rotate the workpiece 180°, and then repeat S3 to grind the other side of the workpiece;

[0058] S5, the driving motor 41 rotates 180° counterclockwise, and then the polished workpiece is removed, and the polishing work is completed.

[0059] The working principle of the present invention is as follows:

[0060] During operation, the workpiece is placed outside the housing 5, and the driving motor 41 rotates 180° clockwise to drive the annular plate 421 to rotate 180°. The positioning pin 551 moves from the end of the arc groove 422 close to the center of the annular plate 421 to the end away from the center of the circle. Under the restriction of the housing 5, the connecting rod 55 moves toward the outside of the housing, thereby driving the clamping plate 53 to move outward to clamp the workpiece.

[0061] Start the second electric slide 33 to move the second slide 24 along the length direction of the base 1. When the workpiece moves to a suitable grinding position, close the second electric slide 33. Then start the grinding wheel 12 and start the first electric slide 31 to move the workpiece toward the grinding wheel 12 to start grinding.

[0062] After one surface of the workpiece is polished, it passes through the first electric slide 31 and moves away from the grinding wheel. After the workpiece moves to a safe distance, the drive motor 41 is rotated 180° clockwise again. At this time, the workpiece is still clamped by the clamping assembly. The positioning pin 551 is in the arc groove 422 at one end away from the annular plate 421. The side wall of the arc groove 422 pushes the two positioning pins 551 to make the shell 5 rotate synchronously around the central axis of the drive shaft 42. The limit rod 51 on the shell 5 rotates synchronously and squeezes the limit pin downward. 23. After the driving shaft 42 rotates 180°, the two limiting rods 51 stay at the position of the limiting pin 23 again. Under the action of the elastic force of the spring 231, the limiting pin 23 is inserted into the limiting hole 511 to fix the housing 5, thereby realizing the flipping of the workpiece. After the workpiece is flipped, due to the different sizes of the end face of the workpiece and the bottom face of the leg, the workpiece needs to be moved to a suitable grinding position again by the second electric slide 33. Then, the workpiece is controlled by the first electric slide 31 to approach the grinding wheel 12 to start the grinding work of the other side of the workpiece.

[0063] After the other side of the workpiece is polished, the workpiece is moved to a safe position by the first electric slide rail 31, the drive motor 41 rotates 180° counterclockwise, the clamping assembly releases the fixation of the workpiece, the polished workpiece is removed, and the polishing work is completed.

[0064] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
