Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary processing mechanisms, and more specifically, to an auxiliary processing mechanism for parts. Background Technique

[0002] Mechanical parts, also known as mechanical components, are the basic components that make up a machine. During the production process of mechanical parts, multiple processing procedures are required. When machining mechanical parts, an auxiliary mechanism (such as a positioning fixture and tooling) is needed to fix them for subsequent machining of the mechanical parts.

[0003] For example, a positioning tooling for machining mechanical parts disclosed in a patent with the publication number CN220922136U includes a fixed base. A support column is connected to the fixed base. A first connecting clamp is connected to the middle of the support column. A lower clamping area is provided in the middle of the first connecting clamp. A fixing plate is connected to the top of the support column. A driving cylinder is connected to the fixing plate. The driving shaft of the driving cylinder passes through the fixing plate and is connected to a second connecting clamp. An upper clamping area that cooperates with the lower clamping area is provided on the second connecting clamp. Locking components for pressing and positioning the product are connected to the left, middle, and right sides of the lower clamping area. Although this positioning tooling can improve the stability of part fixation, during its actual use, this positioning tooling can only fix one part at a time. After machining, it is also necessary to loosen and disassemble the machined part and then re-clamp and fix the next part. This method has low processing efficiency and thus needs to be improved. Summary of the Utility Model

The holding assembly includes a moving ring disposed in the lifting cavity with both ends extending out of the notch grooves. A plurality of thorns that can penetrate into the elastic pad are provided at the extending ends of the moving ring.

[0009] Preferably, a spring for driving the moving ring to move towards the elastic pad is also provided in the lifting cavity. A handle is further provided at the extending end of the moving ring, and the handle is used to drive the moving ring to move.

[0015] 1. In the present utility model, through the arrangement of a plurality of clamping grooves, when the first fixing plate and the second fixing plate approach each other, a plurality of parts can be clamped and fixed simultaneously. Compared with the existing positioning tooling that can only clamp one part in one operation, in the present utility model, a plurality of parts can be fixed or released in one operation, and the efficiency is higher.

[0016] 2. In the present utility model, multiple first fixing plates and second fixing plates are provided.

[0030] To further understand the content of the present utility model, the present utility model will be described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present utility model and not for limiting it.

[0031] The following will further elaborate on this embodiment Figures 1 - 6 in further detail.

[0032] Please refer to Figures 1 - 2 , a part auxiliary processing mechanism in this embodiment includes a base 100. A moving cavity 200 is provided in the base 100 along its width direction. A chute 130 communicating with the moving cavity 200 is provided on the upper end surface of the base 100. A first slider 220 and a second slider 230 that are movable and extend upward are oppositely provided in the chute 130. A plurality of detachable first fixing plates 110 are provided on the first slider 220. A plurality of detachable second fixing plates 120 are provided on the second slider 230. A plurality of clamping grooves 111 are oppositely provided on the opposite side walls of the first fixing plate 110 and the second fixing plate 120. The first fixing plate 110 and the second fixing plate 120 approach each other to fix the part 140 with the clamping grooves 111. A driving assembly for driving the first fixing plate 110 and the second fixing plate 120 to move relatively is further provided in the moving cavity 200.

[0033] In this embodiment, the base 100 is installed on the workbench by bolts. The first fixing plate 110 and the second fixing plate 120 are slidably installed on the upper side surface of the base 100 and are respectively connected to the corresponding first slider 220 and second slider 230. When the first fixing plate 110 and the second fixing plate 120 approach each other, the clamping grooves 111 are used to clamp the part 140 to fix it for subsequent processing. After the part 140 is processed, move the first fixing plate 110 and the second fixing plate 120 away from each other to release the fixation of the clamping grooves 111 on the part 140. At this time, the processed part 140 can be removed;

[0034] Among them, through the arrangement of a plurality of clamping grooves 111, when the first fixing plate 110 and the second fixing plate 120 approach each other, a plurality of parts 140 can be clamped and fixed simultaneously. Compared with the existing positioning tooling that can only clamp one part 140 in one operation, the auxiliary processing mechanism in this embodiment can perform or release the fixation of a plurality of parts 140 in one operation, with higher efficiency;

[0035] Among them, the cross-section of the clamping groove 111 provided on the first fixing plate 110 and the second fixing plate 120 is V-shaped, and the elastic member is filled inside the clamping groove 111. With this structure, when the first fixing plate 110 and the second fixing plate 120 approach each other, the opposite clamping grooves 111 can approach each other to clamp the part 140 located between them. At this time, the elastic member can buffer the part 140 to avoid damaging it;

[0036] Among them, through the detachable setting of the first fixing plate 110 and the second fixing plate 120, the first fixing plate 110 and the second fixing plate 120 on the base 100 can be replaced, so as to adapt to parts 140 with different diameters;

[0037] Among them, by providing a plurality of first fixing plates 110 and second fixing plates 120, when the length of the part 140 is relatively long, the relative stacking of the plurality of first fixing plates 110 and the plurality of second fixing plates 120 can be used to increase the fixing height of the clamping groove 111 for the part 140, enhance its fixing effect, and prevent the part 140 from tipping over when the first fixing plate 110 and the second fixing plate 120 clamp the part 140;

[0038] Among them, through the setting of the driving component, it can drive the first slider 220 and the second slider 230 to move relatively, so that the first fixing plate 110 and the second fixing plate 120 located on them move relatively, and finally fix or release the fixing of the part 140.

[0039] As Figure 2 shown, in this embodiment, the driving component includes a rotating shaft 210 provided in the moving cavity 200 and extending out at one end. The rotating shaft 210 is rotatably arranged. The rotating shaft 210 is threadedly passed through the first slider 220 and the second slider 230. The rotation of the rotating shaft 210 is used to drive the first slider 220 and the second slider 230 to move relatively. A holding component for preventing its accidental rotation is also provided at the extending end of the rotating shaft 210.

[0040] In this embodiment, both ends of the rotating shaft 210 are rotatably installed on the side wall of the moving cavity 200 through bearings. Thus, the rotation of the rotating shaft 210 is realized. Due to the restriction of the sliding groove 130 on the first slider 220 and the second slider 230, when the rotating shaft 210 rotates, the first slider 220 and the second slider 230 will move relatively along the axial direction of the rotating shaft 210, thereby driving the first fixing plate 110 and the second fixing plate 120 to move relatively, and finally fixing or releasing the fixing of the part 140;

[0041] The rotating shaft 210 is provided with threads that match the first slider 220 and the second slider 230, and the threads are arranged in reverse symmetry. With this structure, when the rotating shaft 210 rotates, the first fixing plate 110 and the second fixing plate 120 will move away from or approach each other instead of moving in the same direction.

[0042] By setting the holding component, when the rotating shaft 210 stops rotating, the holding component can fix it so that it will not rotate by mistake, thereby causing the part 140 to be accidentally released.

[0043] like Figures 1 - 6 As shown, in this embodiment, an elastic pad 310 is provided on the base 100 and is sleeved on the outside of the rotating shaft 210. A lifting chamber 300 with an opening at one end is provided at the protruding end of the rotating shaft 210 along its axial direction. A removable blocking cap 301 is provided at the opening of the lifting chamber 300. Notch grooves 600 communicating with the outside are provided on both sides of the lifting chamber 300. The retaining component includes a movable ring 302 which is arranged in the lifting chamber 300 and protrudes out of the notch grooves 600 at both ends. A plurality of needles 303 which can pierce the elastic pad 310 are provided at the protruding end of the movable ring 302.

[0044] In this embodiment, when the rotating shaft 210 needs to be fixed, the moving ring 302 can be moved to drive the needle 303 to extend into the elastic pad 310. Due to the friction between the needle 303 and the elastic pad 310, the moving ring 302 cannot be rotated. Because the notch groove 600 limits the moving ring 302, the rotating shaft 210 is finally fixed. When the rotating shaft 210 needs to be rotated, the moving ring 302 can be moved to make the needle 303 separate from the elastic pad 310, thereby releasing the fixing of the rotating shaft 210.

[0045] The blocking cap 301 is threadedly connected to the protruding end of the rotating shaft 210 to seal the lifting chamber 300 so that the moving ring 302 can be installed. There are multiple needles 303. Through this structure, the friction between the moving ring 302 and the elastic pad 310 can be increased.

[0046] like Figure 3 As shown, in this embodiment, a spring 304 for driving the moving ring 302 to move toward the elastic pad 310 is further provided in the lifting chamber 300 , and a handle 305 is provided at the protruding end of the moving ring 302 , and the handle 305 is used to drive the moving ring 302 to move.

[0047] In this embodiment, one end of the spring 304 abuts against the plug cap 301, and the other end abuts against the moving ring 302. Under the thrust of the spring 304, the moving ring 302 can automatically move towards the elastic pad 310. When it is necessary to release the fixation of the rotating shaft 210, the handle 305 can be pulled in the direction away from the elastic pad 310 to make the lancet 303 extend out of the elastic pad 310.

[0048] Among them, when it is necessary to rotate the rotating shaft 210, the handle 305 can be rotated. Due to the limitation of the moving ring 302 by the notch groove 600, the moving ring 302 can drive the rotating shaft 210 to rotate.

[0049] As Figures 1 - 2 shown, in this embodiment, the first fixing plate 110 located at the bottom is provided with a first threaded hole, and the first slider 220 is provided with a second threaded hole corresponding to the first threaded hole. The first fixing plate 110 located at the bottom is also provided with a first bolt 240 for connecting the first slider 220.

[0050] In this embodiment, when it is necessary to fix parts 140 with different diameters, the first bolt 240 located on the first fixing plate 110 can be removed to release the connection with the first slider 220, so as to replace the first fixing plate 110 with different sizes of clamping grooves 111.

[0051] Among them, the second fixing plate 120 and the second slider 230 are connected by the same structure.

[0052] As Figure 1 shown, in this embodiment, the upper end surface of the base 100 and on both sides extend upward to form limit plates 101, and the limit plates 101 are used to limit the moving directions of the first fixing plate 110 and the second fixing plate 120.

[0053] In this embodiment, through the arrangement of the limit plates 101, when the first fixing plate 110 is replaced and connected to the first slider 220, the first fixing plate 110 is limited by the limit plates 101 and will not shake during the connection, so that the first fixing plate 110 and the second fixing plate 120 can be kept parallel and will not affect the subsequent fixation of the parts 140.

[0054] As Figures 1 - 5 shown, in this embodiment, clamping grooves 500 are relatively arranged on one side surface of the first fixing plate 110 along its width direction, and the first fixing plate 110 located at the top is provided with a clamping block 510 that can extend into the clamping grooves 500 of the first fixing plate 110 located at the bottom.

[0055] In this embodiment, when stacking the first fixing plates 110, the clamping blocks 510 on the top first fixing plate 110 can be snapped into the clamping slots 500 of the bottom first fixing plate 110, thereby completing the preliminary connection of the upper and lower first fixing plates 110.

[0056] As Figures 1 - 5 shown, in this embodiment, third threaded holes 520 are relatively provided on both sides of the upper end surface of the first fixing plate 110, and a second bolt 400 for connecting the bottom first fixing plate 110 is provided on the top first fixing plate 110.

[0057] In this embodiment, when it is necessary to fix a plurality of adjacent first fixing plates 110, the second bolt 400 can pass through the third threaded holes 520 to complete the fixation of the plurality of first fixing plates 110.

[0058] Working principle: When it is necessary to fix the part 140, first select the first fixing plate 110 and the second fixing plate 120 with a suitable clamping groove 111 size according to the diameter of the part 140, connect them through the first bolt 240 and the first slider 220 and the second slider 230, and then stack a plurality of first fixing plates 110 and second fixing plates 120 through the second bolt 400 according to the height of the part 140. Then pull the handle 305 and rotate it to release the contact between the thimble 303 and the elastic pad 310, drive the moving ring 302 to rotate, make the first fixing plate 110 and the second fixing plate 120 approach each other, fix the part 140, and facilitate subsequent processing.
