Description

Technical Field

[0001] The invention relates to the technical field of machining tooling, in particular to the technical field of tooling for machining robot swivel joints. Background Art

[0002] The horizontal distance between the first and second axes of the swivel joint is required to be 162±0.03mm, the vertical distance is required to be 282±0.03mm, and the vertical distance is required to be 0.02mm. In order to meet the movement accuracy of the whole machine, the spacing between different axes of the components must meet higher requirements. Therefore, ordinary processing tools are placed horizontally and clamped to complete the processing of one axis in one process, and then turned over and clamped for the second process. This cannot meet the simultaneous processing of two axes, and it is also very difficult to meet the dimensional accuracy requirements. The material of the swivel joint is ductile cast iron. The characteristics of robot joints are that they require lightweight, their structure is relatively complex, and the wall thickness is thin, so the structural rigidity is relatively low, and the processing process is prone to vibration, so there are also high requirements for the tooling used for processing.

[0003] The patent document with publication number CN207223420U discloses a robot joint processing tooling, including a front tooling and a back tooling. The processing tooling needs to first process the front side of the joint by the front tooling, and then process the back side of the joint by the back tooling after completion; two tools are needed during processing, and the workpiece needs to be fixed twice, which is very troublesome and the processing efficiency is not high.

[0004] The patent document with publication number CN212043655U discloses a robot base positioning tool, including a base plate, a vertical plate and a workpiece, the vertical plate is vertically fixed to the base plate, the workpiece has a joint portion and a flange portion respectively arranged on the base plate and the vertical plate, an auxiliary support is arranged between the joint portion and the base plate, and axial positioning columns fixed to the base plate are arranged on both sides of the auxiliary support; although the positioning tool can effectively fix the workpiece, during processing, the processing surface with the vertical plate will be blocked, resulting in one of the surfaces failing to meet the processing conditions, and secondary processing is still required. Summary of the invention

[0005] The purpose of the present invention is to solve the problems in the prior art and to provide a tooling for robot swivel joint processing that can solve the above problems.

[0006] To achieve the above-mentioned objectives, the present invention proposes a tooling for robot swivel joint processing, comprising a base plate and a vertical plate, wherein the vertical plate is vertically arranged on the base plate, the vertical plate is provided with a hollow groove, the outer periphery of the hollow groove is provided with a plurality of center positioning parts, the base plate is provided with a bottom support part, and a plurality of side locking parts are provided on both sides of the bottom support part.

[0007] Preferably, the bottom support member comprises a support seat and a support stud, a thread groove matching the support stud is vertically opened on the support seat, the support stud is threadedly installed in the thread groove, and a support flat head is provided on the top of the support stud.

[0008] Preferably, the side locking member comprises a side locking seat and a locking stud, the side locking seat is transversely provided with a thread groove matching the locking stud, the locking stud is threadedly installed in the thread groove, and the locking stud is parallel to the base plate.

[0009] Preferably, three locking studs are provided, two locking studs are provided on one side of the supporting stud, and one locking stud is provided on the other side.

[0010] Preferably, the locking stud is arranged perpendicular to the supporting stud, and the locking stud is located above the supporting flat head.

[0011] Preferably, a plurality of reinforcing ribs are provided at the bottom of the vertical plate, the side surfaces of the reinforcing ribs are connected to the vertical plate, the bottom of the reinforcing ribs is connected to the bottom plate, and vertical plates are provided on both the front and back sides of the vertical plate.

[0012] Preferably, the center positioning member includes a positioning seat and a positioning stud, the positioning seat is provided with a plurality of thread grooves, the positioning studs are threadedly installed in the thread grooves, and the positioning studs are parallel to the vertical plate.

[0013] Preferably, there are four positioning studs, which are evenly distributed in a circle.

[0014] Preferably, the robot swivel joint comprises one axis and two axes connected to each other, wherein the one axis is mounted on the vertical plate, the other axis passes through the hollow groove, and the center positioning member positions and locks the outer circular part of the one axis; the two axes are mounted on the bottom plate, the bottom support member supports the outer circular part of the two axes, and the side locking member locks the two sides of the two axes.

[0015] Preferably, during installation, the maximum outer circle of one axis is first positioned by the center positioning member to complete the center positioning of one axis and lock the center of one axis by the positioning stud; the outer circle of the two axes is then supported by the bottom support member; finally, the two sides of the two axes are locked by the side locking member to complete the clamping.

[0016] Beneficial effects of the present invention: the structure of the present invention can ensure the dimensional tolerance and form and position tolerance of the first and second axes. During installation, the only side of the swivel joint that does not need to be processed faces the bottom of the base plate, and the other surfaces that need to be processed can face the main axis of the machine tool, so that all processing contents can be completed after one-time positioning and clamping, thereby improving the processing efficiency. After the vertical plate of the present invention is installed on the base plate, the verticality between the two is within 0.05mm, ensuring the accuracy between the relative dimensions and meeting the dimensional accuracy requirements. The vertical plate is effectively hollowed out without affecting the rigidity and clamping support, so that the back is supported by the vertical plate. The side processing content is processed by penetrating the back of the vertical plate to avoid secondary processing; the robot swivel joint is basically an irregular curved surface as a whole, with a position center deviation. The present invention divides the maximum outer circle of one axis into four parts, locks the center of one axis by a positioning stud, and effectively positions the center. The outer circle of the two axes is supported by a supporting stud, and the stud can be locked after the center adjustment of the first piece is determined. For subsequent mass production, the center can be determined by directly loading and clamping. Finally, the locking stud is used to strengthen the locking. Not only can it be quickly positioned and clamped in the mass production stage, but there is no need to calibrate each blank, which greatly shortens the processing cycle.

[0017] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
