DETAILED DESCRIPTION

[0025] The preferred embodiments of the utility model are described in detail below with reference to the drawings, so that the advantages and features of the utility model can be more easily understood by those skilled in the art, and the protection scope of the utility model can be more clearly and explicitly defined. EMBODIMENT

[0026] Referring to Figures 1-3 , Figure 6 , a stator seat tool clamp for punching, comprising a positioning table 1, the positioning table 1 has two inclined abutting planes 6, the abutting plane is a long block body with an inclined plane arranged on the positioning table 1, the included angle of the two abutting planes 6 is upwardly arranged, the stator seat 9 has two positioning part ones 91 on the side wall, which are overlapped on the abutting plane 6, the positioning table 1 is provided with two groups of stroke-fixed clamping positioning assemblies one, each group of clamping positioning assemblies one is used for abutting with a positioning part one 91, and the force direction of the clamping positioning assembly one is inclined downward along the abutting plane 6.

[0027] The positioning table 1 is also provided with an abutting piece 8, the stator seat 9 has a positioning part two 92 in the axial direction, which is used for abutting with the abutting piece 8, and the positioning table 1 is also provided with a clamping positioning assembly two for pressing the positioning part two 92 on the abutting piece 8.

[0028] Among them, the clamping positioning assembly one comprises a linear driving assembly and a pressure head one 73 arranged at the end of the linear driving assembly, and the linear driving assembly can be a cylinder.

[0029] Among them, the clamping positioning assembly two comprises a horizontal rotating assembly and a pressure head two 71 arranged at the rotating end of the horizontal rotating assembly, and the horizontal rotating assembly can be a rotating cylinder, and the horizontal rotating assembly rotates to make the pressure head two 71 abut with the positioning part two 92.

[0030] Among them, the pressure head two 71 is provided with a roller 72 for abutting with the positioning part two 92.

[0031] Wherein, refer to Figure 4 The preferred scheme is to integrate the linear driving assembly and the horizontal rotating assembly into a rotary clamping cylinder 7. The reason for integration is that the working principle of the rotary clamping cylinder 7 is that the time for completing the rotating position is inconsistent with the time for completing the extension and contraction, and the specific parameters are controllable. For example, in the rotary clamping cylinder 7 of the present scheme, after the rotation is completed, the extension and contraction action is still performed, so as to achieve the positioning of the positioning part one 91 and the positioning part two 92 respectively. Specifically, the QCK series rotary clamping cylinder 7 of Yadea can be used.

[0032] Wherein, the positioning table 1 is provided with two inclined blocking strips 10, and each blocking strip 10 is used to prevent the positioning part one 91 from separating from the abutting plane 6. Specifically, the positioning part one 91 is a side of a protruding structure on the wall of the stator seat 9, and a second plane forming an included angle with the positioning part one 91 is arranged on the protruding structure. The second plane is set as the positioning part three 93. When the positioning part one 91 is about to separate from the abutting plane 6, the positioning part three 93 will be in contact with the blocking strip 10 to prevent it from separating. The structure of the blocking strip 10 cooperating with the abutting plane 6 makes the positioning position of the stator seat 9 on the abutting plane 6 not deviate too much in the actual operation of the worker.

[0033] Wherein, refer to Figure 5 The positioning table 1 is provided with two installation plates 2, and each blocking strip 10, abutting plane 6, clamping and positioning assembly one, abutting piece 8 and clamping and positioning assembly two are arranged on one installation plate 2. The distance between the installation plates 2 can be adjusted. Specifically, the two installation plates 2 jointly slide on a group of slide rods 3. The slide rods 3 are provided with fixing pieces 5 for fixing the positions of the installation plates 2. The positioning table 1 is provided with a connecting block 4, and the slide rods 3 are connected with the connecting block 4. Specifically, the slide rods 3 can be threaded rods or have partial threads thereon to realize the connection and fixation between structures. The fixing pieces 5 can adopt nuts. The connecting block 4 can be fixed on the positioning table 1 by bolts. The slide rods 3 can be fixed with the connecting block 4 by nuts.

[0034] Working principle and process:

[0035] When using the tool of the present scheme, the position of the installation plate 2 is adjusted and fixed according to the specification of the stator seat 9. Then the stator seat 9 is taken out and placed horizontally on the abutting platform, and manually pushed inward to realize the pre-positioning of the positioning part two 92 and the abutting piece 8. Then the rotary clamping cylinder 7 is rotated and contracted. When the rotation is terminated, the clamping and positioning of the positioning part two 92 and the abutting piece 8 is realized. Then, the rotary clamping cylinder 7 continues to contract for a period under its own working, which is in contact with the positioning part one 91 and stops at the end of the stroke, realizing the positioning and fixation of the stator seat 9. The rollers 72 on the pressing head two 71 can reduce the difficulty of rotating the stator seat 9 in the circumferential direction.

[0036] The above only describes the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation or direct or indirect application in other related technical fields based on the content of the present application specification and drawings is also included in the patent protection scope of the present application.
