Technical Field

[0001] The utility model relates to the technical field of processing jigs, and in particular to a multi-dimensional adaptive curved surface replacement jig. Background Art

[0002] A processing fixture is a loading device for fixing products. It can adapt and clamp the periphery of the product to ensure the stability of the product during processing.

[0003] Surface processing jigs are a main type of jigs used in jig processing. Since some products are non-standard products, their surfaces will have more complex curved surfaces. Ordinary jigs cannot stabilize the shape of the jigs well and are prone to processing errors. Therefore, special surface processing jigs are used to correspond to the corresponding processed products to ensure that the shapes of the jigs and products are adapted, and the products fit the inner surface of the jig without shaking during processing.

[0004] The curved surface jigs in the prior art generally adopt the method of one curved surface jig corresponding to one specification of parts. However, due to the excessive specifications of curved surface products that need to be processed, each time the processing jig is replaced, the processing jig needs to be replaced as a whole, which greatly increases the cumbersome processing process. Manual replacement is required during replacement, which greatly reduces the processing efficiency. Therefore, the curved surface processing jigs in the prior art have the problem of being unable to adapt to a variety of products, resulting in a cumbersome process. Utility Model Content

[0005] The purpose of the utility model is to adopt a jig base with a multi-dimensional detachable structure and be equipped with equipment capable of semi-automatic processing, thereby ensuring that the shape of the jig base can be fine-tuned based on different product specifications, thereby achieving the effect of improving work efficiency.

[0007] Preferably, the telescopic portion includes a covering rod sleeved on the surface of the sliding push rod, the covering rod is slidably connected to the surface of the sliding push rod, and the covering rod has elastic deformation performance.

[0008] Preferably, the covering rod has an elastic protrusion protruding in the direction of the sliding push rod, and the elastic protrusion is in contact with the surface of the sliding push rod and is always in an elastically deformed state.

[0009] Preferably, an elastic groove is provided on the surface of the sliding push rod, and the size and depth of the elastic groove are adapted to the size of the elastic protrusion.

[0010] Preferably, a guide surface is provided in the elastic slot, and the guide surface is inclined toward the bottom of the elastic slot and extends toward the length direction of the sliding push rod.

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] refer to Figure 1 The mechanism includes several jig bases 1, which are connected in a detachable manner to form an integral jig base. A detachable connection structure 11 is provided between the jig bases 1. The jig base 1 is divided into four parts. The two left parts have mutually engaged clamping parts extending toward the two right parts. The surfaces of the two right parts are provided with clamping grooves for inserting the clamping parts. When the clamping parts are inserted into the clamping grooves, the jig will form a whole and remain stable. At this time, the product can be placed in the curved surface depression of the assembled jig surface for processing.

[0027] A fixed structure 2 is provided on a fixture base 1, and the fixed structure 2 includes a sliding push rod 21 and a synchronous motion module 3 that drives the sliding push rod 21 to move. The synchronous motion module 3 includes a motion base that matches the thickness of the fixture base 1 and two linear synchronous modules arranged on the motion base. A synchronous motor 31 is fixedly provided on one side of the motion base, and the output end of the motor extends into the interior of the motion base. Two synchronous motion module chains are also provided inside the motion base, which can realize rotation in opposite directions driven by the output end of the motor. Two sliding blocks 32 are slidably provided on the surface of the motion base, and a slide groove of the linear module is also provided on the surface of the motion base. The two sliding blocks 32 move synchronously in opposite directions along the slide groove driven by the synchronous motor 31.

[0028] A telescopic portion 22 is sleeved on the sliding push rod 21, and the telescopic portion 22 is connected to a covering rod 221 sleeved on the surface of the sliding push rod 21. The covering rod 221 is slidably connected to the surface of the sliding push rod 21 and can slide along the length direction of the sliding push rod 21. The covering rod 221 is a hollow structure, and its hollow cavity is slightly larger than the cross-sectional area of ​​the sliding push rod 21. An elastic protrusion with high elasticity is integrally formed in the cavity of the covering rod 221 in the direction toward the sliding push rod 21, and the elastic protrusion is always in an elastic state. The deformation state can increase the friction between the covering rod 221 and the sliding push rod 21, ensuring the stability of the covering rod 221. An elastic groove 222 is provided on the sliding push rod 21. The size and depth of the elastic groove 222 are adapted to the size of the elastic protrusion. When the covering rod 221 moves to the elastic groove 222, the elastic protrusion will enter the elastic groove 222, so that the covering rod 221 can no longer be pushed. At this time, the sliding of the covering rod 221 is at a critical point, and a spring is provided in the elastic groove 222. The guide surface 223 which is inclined toward the bottom of the elastic slot 222 and extends along the length direction of the sliding push rod 21 can make the elastic protrusion smoothly enter the elastic slot 222 and make the covering rod 221 be able to be pulled out when the covering rod 221 is pulled in the opposite direction, so that the elastic protrusion can move along the guide surface 223. Two fixing members 23 are fixedly arranged on the surface of the telescopic part 22 and the sliding rod. A fixing groove body 24 is provided on the fixture base 1 for the fixing member 23 to extend into and engage with, and a fixing slide groove is provided on the sliding push rod 21 for the fixing member 23 to slide. When the fixing piece 23 is connected and enters the corresponding fixture base, it pushes the covering rod 221, so that the fixing piece 23 slides in the fixed slide groove. When the covering rod 221 can no longer slide, the two fixture bases are just snap-fitted and interlocked, so that one of the fixture bases follows the movement of the covering rod 221. A thrust block 4 is fixedly provided at one end of the covering rod 221 away from the synchronous motion module 3. The thrust block 4 can facilitate the operator to push the covering rod 221, so the cross-sectional area of ​​the thrust block 4 is larger than the cross-sectional area of ​​the covering rod 221.

[0029] When using this jig, if part of the jig needs to be replaced, you only need to disassemble the corresponding jig base 1 and fix the replaced jig base 1 on the fixing part 23. At this time, the horizontal position of the replaced jig base is adjusted by the synchronous motor 31. When the horizontal position is aligned, push the push block 4 again. When the elastic protrusion enters the elastic card slot 222, the push block 4 can no longer push. At this time, the replaced jig base 1 is installed, and the detachable connecting structure 11 on the jig base 1 is correspondingly snapped in, thereby completing the technical effect of semi-automatically replacing the jig base 1 and adapting to products of different specifications.

[0030] The above embodiments are used to further illustrate the present invention, but the present invention is not limited to these specific implementations. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention should be understood to be within the protection scope of the present invention.
