Description

Technical Field

[0001] The invention relates to the technical field of vise processing, and more particularly to a punching mechanism for vise processing. Background Art

[0002] In the current manufacturing industry, the production process of vises mainly relies on casting technology. Although this traditional casting process can meet basic production needs, it has obvious shortcomings in product quality, especially in the processing of shaft connecting holes. Due to the influence of factors such as the flow characteristics of metal liquid and solidification shrinkage during the casting process, casting residues are often left on the inner wall of the hole. These residues not only affect the matching accuracy between parts, but also may cause poor movement of the shaft. At the same time, the surface of the casting, especially the edge, often has more serious burr problems. These burrs not only affect the appearance of the product, but also have an adverse effect on subsequent assembly and use.

[0003] In the current production process, the treatment of these casting defects is still at a relatively primitive stage. The existing processing equipment can only process the various components of the vise separately. This decentralized processing method not only increases the process links, but also prolongs the production cycle. For example, the shaft connection hole needs to be drilled or reamed first, and then deburred separately. This fragmented processing method not only reduces production efficiency, but also increases labor costs. More importantly, due to the lack of a unified processing benchmark, it is easy to cause inconsistent processing accuracy between various processes, which ultimately affects the overall quality of the product. Summary of the invention

[0011] Preferably, a plurality of limit blocks are installed on the side wall of the adjustment sleeve, a limit sleeve is respectively installed at the lower end of each of the bonding plates, and the limit sleeve is slidably connected to the limit block. This structure realizes precise guiding and limiting of the movement of the bonding plate through the sliding cooperation between the limit block and the limit sleeve, thereby preventing the bonding plate from deflecting or shaking during operation.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides a vise punching mechanism having the following features:

[0018] Beneficial effects:

[0019] This mechanism innovatively integrates the functions of drilling cleaning and burr treatment in one device. Through the precisely designed drill bit and friction disc combination, it realizes the cleaning of the residue inside the rotating hole of the vise and the synchronous treatment of the burrs on the edge of the hole. This integrated design not only improves the processing efficiency, but also ensures the consistency of the processing quality, avoiding the precision errors that may be caused by traditional step-by-step processing. Through the cooperation of the follower sleeve, spiral strip and transverse rod, automatic torque control is realized during the processing. When the friction force exceeds the preset threshold, the transverse rod will automatically disengage from the vertical groove, effectively preventing damage to the workpiece surface caused by excessive grinding. This intelligent Torque control ensures the safety of the machining process and the surface quality of the workpiece. The combined design of the threaded sleeve, telescopic sleeve and compression spring enables precise adjustment of the machining pressure. The operator can adjust the preload of the compression spring through simple wrench operation to precisely control the grinding force. This adjustability not only improves the machining flexibility, but also can adapt to vises of different materials and different machining requirements. The coordination of the oblique rod, return spring and fixed plate ensures the stability of the friction plate in the vertical direction. In particular, the rounded corner design of the fixed plate combined with the spring pressure provides a reliable self-locking function, which effectively prevents shaking and detachment during machining.

No less than eight groups of transverse holes 26 are provided on the side wall of the adjusting sleeve 24, and a transverse rod 27 is slidably connected in each transverse hole 26. A vertical groove 28 symmetrical to the transverse rod 27 is provided on the side wall of each follower sleeve 22, and the transverse hole 26 abuts against the vertical groove 28. The transmission mechanism also includes a fixed sleeve 29 fixedly installed on the frame 11, and a friction disk 25 is coaxially installed on the fixed sleeve 29.

[0033] See also Figure 1When cleaning the rotating hole of the vise and the burrs at both ends of the rotating hole, first place a part of the vise on the receiving plate 12, and then fix it through the corresponding clamping mechanism, then place the rotating hole of the vise on the bottom hole 13 coaxial with the drill bit 21, then start the motor 15 to drive the drill bit 21 to rotate, and make the frame 11 move downward, and then insert the drill bit 21 into the rotating hole in the vise. Since the spiral hole of the vise and the drill bit 21 have the same diameter, the residue in the rotating hole will be cleaned, and then the burrs on one end will be cleaned through the friction disk 25, thereby completing the two processing processes synchronously.

[0034] The rotating hole described in the present application is a rotating hole opened between two parts of the vise for rotating through an axis.

[0035] Since the friction disc 25 should only clean the burrs when rotating, there is no need to limit the torque to a reasonable range. If the torque is too large, it will cause additional damage to the surface of the vise. Please refer to Figure 5 and Figure 6 Since the spiral strip 23 inside the follower sleeve 22 is connected to the cutting groove of the drill bit 21, the follower sleeve 22 and the drill bit 21 are always in synchronous rotation, and one end of the plurality of transverse rods 27 is respectively pressed against the corresponding vertical groove 28, see Figure 3 The other ends of the plurality of transverse rods 27 are pressed against the bonding plate 215. Since the bonding plate 215 and the shrinking plate 213 are connected by the compression spring 214, and the shrinking plate 213 is fixedly mounted with a guide rod 216 which is slidably connected in the guide hole 217, and the limit sleeve 219 is slidably sleeved on the limit block 218, when the friction force between the friction disc 25 and the vise exceeds the elastic force of the plurality of compression springs 214, please refer to Figure 6 , the transverse rod 27 will release the connection with the vertical groove 28, so that the transverse rod 27 expands outward and then releases the connection between the follower sleeve 22, so that only a torque of corresponding force will be generated to avoid the situation where the grinding force is too large to damage the surface of the pliers.

[0036] When the grinding force needs to be adjusted, since the fixed sleeve 29 and the intermediate sleeve 210 are respectively fixed to the frame 11, the drill bit 21 is rotatably connected in the fixed sleeve 29 and the intermediate sleeve 210, and since the threaded sleeve 101 is threadedly connected in the intermediate sleeve 210, the operator opens two wrenches on the threaded sleeve 101 and the fixed sleeve 29 respectively and then rotates the threaded sleeve 101. Figure 4At this time, the thrust will be transmitted to the telescopic sleeve 211, and then the telescopic sleeve 211 will be pushed to slide downward. Since the limit sleeve 219 is stuck on the limit block 218, the fitting plate 215 will not slide downward when the telescopic sleeve 211 slides downward, and then the retractable plate 213 will slide and retract in the inclined groove 212, and then the compression spring 214 will be compressed, thereby changing the initial elastic force of the compression spring 214, thereby completing the torque adjustment process.

[0037] The limiting mechanism includes a plurality of oblique grooves 31 provided on the side wall of the adjusting sleeve 24, an oblique rod 32 is slidably connected in the oblique groove 31, an annular groove 102 is provided on the outside of the follower sleeve 22, a return spring 33 is respectively sleeved and installed on each oblique rod 32, the other end of the return spring 33 is connected to the inner sleeve 34, the inner sleeve 34 is threadedly connected to the side of the oblique groove 31 close to the outer wall, the limiting mechanism includes a fixed plate 35 slidably connected to the adjusting sleeve 24, a rounded corner 36 is provided on the fixed plate 35, a plurality of stop rods 37 are installed at the lower end of the friction plate 25, and the fixed plate 35 is slidably connected to the plurality of stop rods 37, a plurality of springs 38 are equidistantly installed on the lower end of the fixed plate 35, and the plurality of springs 38 respectively abut against the friction plate 25.

[0038] When the friction disc 25 and the follower sleeve 22 are connected in the vertical direction, please refer to Figure 5 and Figure 6 The return spring 33 is in a compressed state in the initial state, so that the oblique rod 32 is pushed outward along the oblique groove 31, so that it shrinks into the oblique groove 31. At this time, the friction plate 25 is sleeved and fitted in the follower sleeve 22. After fitting in place, the fixed plate 35 is pushed upward. Since there is a rounded corner 36 on the fixed plate 35, when the rounded corner 36 presses on multiple oblique rods 32, the oblique rods 32 are pushed inward, so that the oblique rods 32 are inserted into the annular groove 102, and the fixed plate 35 is fitted on the uppermost end of the stop rod 37, and the spring 38 is always in a compressed state, thereby ensuring that multiple oblique rods 32 are always pressed against the inner wall of the fixed plate 35, thereby ensuring that the oblique rods 32 are always in a fit state with the annular groove 102. At this time, the clamping state is completed, thereby ensuring the stability of use in the vertical direction, and then ensuring the stability of use of the friction plate 25.

[0039] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which will not be described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
