[0004] The above-mentioned general spare part manufacturing clamping device can only meet the clamping needs of specified spare parts. However, due to the different shapes, sizes, and materials of spare parts, the existing clamping device cannot fully adapt to the clamping of all spare parts, limiting the operation range of the clamping device. Moreover, for the clamping of some special spare parts, the entire processing device needs to be replaced, increasing production costs. Therefore, a general spare part manufacturing clamping device is proposed to solve the above-mentioned problems. SUMMARY

[0005] The clamping device for spare part machining provided by the present application can fully adapt to the clamping of all spare parts, limiting the operation range of the clamping device, and for the clamping of some special spare parts, the entire processing device needs to be replaced, increasing production costs.

[0006] The technical solutions adopted by the present application are as follows.

[0007] The utility model provides a clamping device for part machining, including base, adjustable foot setting in the bottom of base, support setting on the base, moving rod rotates in the bottom of base, limit part's limiting mechanism, the adjusting piece of adjusting limiting mechanism and the driving piece of driving moving rod rotation, adjustable foot is uniformly distributed in the four corners of base, the work area is set up on the base, the support is set up in the middle of work area, moving rod is set up in support and moving rod is perpendicular with support, the work area is divided into four groups by support and moving rod, the limiting mechanism and adjusting piece are set up in four subareas of work area, the limiting mechanism and adjusting piece are set up in each group mirror image, the driving piece is set up on the base and the acting end of driving piece corresponds with moving rod.

[0009] As a further improvement of the above technical solution: the outer side of the clamping piece is provided with a rubber piece.

[0010] As a further improvement of the above technical solution: the adjusting piece includes an adjusting strip and a fixing piece limiting the angle of the first rod; the adjusting strip is arranged at the four corners of the work area; the adjusting strip is arc-shaped and the center of the adjusting strip coincides with the hinge point of the first rod; the adjusting strip is provided with a first slot; the fixing piece slides along the first slot and the fixing piece is threaded through the first rod; the first slot is arc-shaped and the center of the first slot coincides with the hinge point of the first rod.

[0012] As a further improvement of the above technical solution: further comprising a detection sensor for detecting whether the adjustable foot is horizontal.

[0013] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0014] 1. The adjustable feet at the four corners adjust the height via threads, and with real-time feedback from the detection sensor, the base can be quickly leveled. Especially when the machine tool vibrates or the ground is uneven, this design can effectively avoid machining errors caused by the base tilting, which is particularly critical for the machining of precision parts.

[0015] 2. The support components and moving rods intersect perpendicularly, dividing the work area into four independent zones. Each zone is equipped with mirror-symmetrical limiting mechanisms and adjusting components. When the drive component (such as a motor) rotates the moving rods, the four moving blocks slide synchronously, pushing the clamping blocks along the first rod via the second rod, thus achieving synchronous clamping of parts at the four workstations. This design is particularly suitable for batch processing scenarios, significantly improving efficiency.

[0016] 3. The arc-shaped track of the adjusting bar is concentric with the hinge point of the first rod, and is slidably fixed along the first groove with the countersunk bolt, allowing for precise adjustment of the unfolding angle of the first rod. This structure ensures the stability of the clamping force direction and can adapt to the clamping requirements of parts of different sizes. For example, when machining a cylinder, the clamping force can be evenly distributed by increasing the angle.

[0017] 4. The diameter of the first hole in the clamping block is larger than that of the second rod, allowing for slight offset during clamping. Combined with the elastic deformation of the rubber parts, this automatically compensates for part dimensional tolerances (within ±0.5mm), preventing part deformation caused by over-positioning. Simultaneously, the array-type clamping components increase the contact area, reducing localized stress concentration.

[0018] 5. Each limiting mechanism is independently installed within its designated area. If a clamping unit is damaged, it can be disassembled and replaced individually without affecting other workstations. Furthermore, by replacing the first rod or adjusting bar of different lengths, larger workpieces can be quickly accommodated, expanding the equipment's application scenarios.

[0028] The outer side of the clamping part 53 is provided with a rubber part 531.

[0029] The adjusting part 6 comprises an adjusting strip 61 and a fixing part 62 for limiting the angle of the first rod 51; the adjusting strip 61 is arranged at the four corners of the working area 11; the adjusting strip 61 is in an arc shape, and the center of the arc of the adjusting strip 61 is consistent with the hinged point of the first rod 51; the adjusting strip 61 is provided with a first groove 611; the fixing part 62 slides along the first groove 611, and the fixing part 62 is threadedly arranged through the first rod 51; the first groove 611 is in an arc shape, and the center of the arc of the first groove 611 is consistent with the hinged point of the first rod 51.
