The following detailed description of the embodiments of the invention is provided.

A rotatable processing jig comprises a fixed seat 1 and a rotary seat 2 rotatably mounted in the fixed seat, wherein a central shaft 3 is rotatably mounted in the rotary seat, and a bracket 4 is mounted at the upper end of the central shaft; clamping jaw subassembly 5 is installed to the roating seat outside, is equipped with driving-disc 6 on the roating seat, and the driving-disc is connected with the roating seat, and when the driving-disc was rotated by the drive belt drive, the roating seat can rotate simultaneously. Set up flange joint portion on the fixing base, can install this tool on the transfer apparatus through wearing to establish the bolt at flange joint portion, realize the continuous processing operation to a plurality of tools.

The central shaft and the driving disc can be respectively driven by a set of moving mechanism to rotate, so that the independent rotation control of the central shaft and the driving disc (rotating seat) is realized, and when the central shaft rotates within a certain angle range, the central shaft is mainly used for finely adjusting the workpiece 20 on the bracket, so that the workpiece position to be processed is aligned with the processing device. The central shaft can be driven to rotate by a servo motor or a stepping motor. The driving disc can be driven by the transmission belt, the driving mechanism of the central shaft and the driving mechanism of the driving disc are not interfered, and the structure is easy to arrange.

When the roating seat rotates, the roating seat can drive the bracket simultaneously and rotate, realizes that the tool is whole rotatory, and then realizes that the work piece rotates at the uniform velocity, and the work piece is rotatory when being fit for the operation of spraying paint, makes the spray gun to the even spraying of work piece surface. Specifically, when the rotating seat rotates, the clamping jaw rod abuts against the supporting rod, so that the bracket and the rotating seat rotate synchronously. By way of example, the upper end of each support rod is provided with a support surface 18, and the support surfaces of the support rods are in the same plane, so that when the workpiece is clamped, the workpiece is ensured to be always kept in a horizontal state.

Of course, according to actual processing needs, only connect one set of actuating mechanism, the required pivoted center pin of drive or driving-disc of drive only carries out a processing content operation also can, and this tool uses in a flexible way, and the function is abundant, but the multiple production operating mode of adaptation. When the workpiece is installed and clamped, only the clamping jaw rod needs to be tightened inwards, the action of tightening the clamping jaw rod can be manually carried out, and an automatic control mode can also be adopted, so that the details are not repeated. When the workpiece is fixed, the workpiece is sleeved on the outer side of the clamping jaw rod, and the clamping jaw rod moves downwards and is supported by the supporting rod. The telescopic arm of the clamping jaw is arranged on the rotating seat through an upper connecting rod and a lower connecting rod, the range limited by the clamping jaw rod can be adjusted in a stepless mode within a certain range, products of different specifications and models can be matched, and the universality is good.

It should be noted that the end of the support rod extends out of the clamping jaw rod, after the clamping jaw rod is spread outwards, the clamping jaw rod is abutted against the inner wall of the workpiece, and at the moment, the end of the support rod protrudes out of the range limited by the clamping jaw rod, so that the workpiece is abutted by the support rod, and the workpiece is kept stable. Meanwhile, the workpiece is very convenient to take and place, the efficiency is high, and when a plurality of sets of jigs are adopted to continuously convey the workpiece to the position of the spray gun, the efficient batch production of the workpiece can be realized.

The bracket comprises a base seat 7, and a plurality of support rods 8 are uniformly distributed on the base seat; the clamping jaw assembly comprises a clamping jaw telescopic arm 9, a clamping jaw finger 10 is installed at the upper end of the clamping jaw telescopic arm, and a clamping jaw rod 11 is vertically installed on the clamping jaw finger; the upper end of the clamping jaw telescopic arm is hinged with an upper connecting rod 12, the lower end of the clamping jaw telescopic arm is hinged with a lower connecting rod 13, and the upper connecting rod and one end of the lower connecting rod, which is different from the clamping jaw telescopic arm, are hinged with the rotating seat.

In an alternative embodiment, the upper end of the telescopic arm of the clamping jaw is provided with a supporting arm 19, and the clamping jaw fingers are detachably arranged at the upper end of the supporting arm. By way of example, the jaw lever is removably mounted within a seat bore of the jaw finger. Specifically, the clamping jaw rod can be inserted into the seat hole and locked and fixed through a set screw horizontally screwed into the clamping jaw finger. Generally, the supporting rods are uniformly distributed with 3 by taking the outer circumference direction of the base seat as the center. Above-mentioned clamping jaw subassembly is equipped with 3 groups with the roating seat circumferencial direction equipartition.

An auxiliary hinging seat 14 is arranged at the upper end of the rotating seat, the auxiliary hinging seat is positioned above a hinging point between the upper connecting rod and the rotating seat, an auxiliary connecting rod 15 is hinged on the auxiliary hinging seat, and one end of the auxiliary connecting rod, which is different from the rotating seat, is hinged in the middle of the upper connecting rod. The upper connecting rod is hinged on an upper hinge seat 16 of the rotating seat, and a groove 17 matched with the tail end of the upper hinge seat is arranged on the auxiliary connecting rod. When the workpiece is not clamped, the clamping jaw telescopic arm is in a drooping state under the action of gravity, and the tail end of the upper hinged seat abuts against the groove of the auxiliary connecting rod, so that the stability of the whole structure is guaranteed.

This processing tool uses easy operation, when carrying out work piece dress card, only needs to tighten up the clamping jaw pole inwards, embolias the work piece and transfers the work piece, until supporting the bracing piece, later unclamps the clamping jaw pole, supports the work piece inner wall simultaneously by each clamping jaw pole, makes the tool form stable supported state to the work piece. After the spray gun is started, the driving disc is driven to rotate along with the driving belt, so that the jig drives the workpiece to rotate, and integral spraying is completed. When the specific position of the workpiece needs to be further processed, such as marking (label spraying), the position of the workpiece can be adjusted finely by driving the central shaft to rotate independently, so that the marking position is aligned with a corresponding processing device (such as a marking device/label spraying device) and then corresponding operation is carried out.

The invention has the advantages of ingenious design and compact structure, can stably clamp and support the workpiece through the clamping claw rod and the supporting rod, and can integrally rotate the jig to perform spraying operation on the surface of the workpiece. And when the specific position of the workpiece needs to be reprocessed, the central shaft can rotate to drive the bracket to finely adjust the position of the workpiece, so that the workpiece is aligned, the operation is very easy, and the processing quality is favorably ensured. The processing jig can efficiently process workpieces in batches, the workpieces can be placed and taken down conveniently, the processing quality is stable and reliable, and meanwhile, the processing jig is high in adaptability and universality and can be matched with various different working conditions.
