During the downward movement of the push block, the trapezoidal block will be pushed to the position of the reducer housing until the push block is locked. The trapezoidal block will fix the position of the reducer housing from different directions. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] This embodiment discloses a positioning tool for machining a reducer housing, such as Figure 1-8 , including a box body 1, a driving motor 2 is fixedly installed on the inner upper surface of the box body 1, a groove 3 is opened on the upper surface of the box body 1, a base 4 is arranged on the top of the box body 1, a ball 5 is movably connected to the lower surface of the base 4, a Tai Chi fish-shaped plate 6 is fixedly installed on the upper surface of the base 4, an arc groove 7 is opened on the side surface of the Tai Chi fish-shaped plate 6, a processing platform 8 is rotatably connected to the top of the base 4, a first fixed groove 9 is opened on the surface of the processing platform 8, a second fixed groove 10 is opened on the surface of the processing platform 8, a guide rail 11 is fixedly installed on one end of the first fixed groove 9, a first slider 12 is arranged on one end of the guide rail 11, a support block 13 is fixedly connected to the upper surface of the first slider 12, a fixing mechanism 14 is arranged above the support block 13, a fixing plate 21 is fixedly installed on one end of the second fixed groove 10, a threaded groove 22 is opened on the surface of the fixing plate 21, and a locking mechanism 23 is connected to the upper surface of the fixing plate 21.

[0029] Furthermore, the base 4 forms a rotating structure through the ball 5 and the groove 3, and the output end of the driving motor 2 passes through the upper surface of the box 1 and is fixedly connected to the base 4. Through the setting of the base 4, the base 4 can be installed with the Tai Chi fish-shaped plate 6. At the same time, the base 4 can rotate on the surface of the groove 3 through the ball 5, so that under the drive of the driving motor 2, the rotation is smoother.

[0030] Furthermore, the fixing mechanism 14 includes a clamping plate 1401, a fixing block 1402, a connecting piece 1403, a connecting ring 1404, a first connecting block 1405, a screw 1406, a support plate 1407 and a threaded tube 1408. The clamping plate 1401 is rotatably connected to the upper side of the support block 13, the fixing block 1402 is welded to the upper surface of the clamping plate 1401, one end of the fixing block 1402 is rotatably connected to the connecting piece 1403, a connecting ring 1404 is welded to one side surface of the connecting piece 1403, the inner ring of the connecting ring 1404 is movably connected to the first connecting block 1405, a screw 1406 is welded to one side of the first connecting block 1405, and the support block A support plate 1407 is fixedly installed at one end of 13, and a threaded tube 1408 is fixedly passed through one side of the support plate 1407. Through the arrangement of the splint 1401, the fixing block 1402, the connecting piece 1403, the connecting ring 1404, the first connecting block 1405, the screw 1406, the support plate 1407 and the threaded tube 1408, when in use, it is only necessary to rotate the screw 1406 at one end of the threaded tube 1408, and the first connecting block 1405 at one end of the screw 1406 will rotate at one end of the second connecting block 15, and at the same time, the connecting piece 1403 will rotate at one end of the fixing block 1402 to pull the splint 1401, thereby completing the rotation locking of the splint 1401.

[0031] Furthermore, the screw 1406 is threadedly connected to the threaded tube 1408, and the screw 1406 forms a rotating structure with the connecting ring 1404 through the first connecting block 1405. Through the setting of the screw 1406, the rotation and clamping of the splint 1401 are driven by rotating the screw 1406. This method is more convenient and the locking is firm.

[0032] Furthermore, a second connecting block 15 is welded to the bottom of the support block 13, and a movable rod 16 is fixedly connected to the surface of one end of the second connecting block 15. A sleeve 17 is sleeved on one end of the movable rod 16, and a spring 18 is welded to the inner ring of the sleeve 17. A sliding block 19 is welded to the surface of one end of the sleeve 17, and one end of the sliding block 19 passes through a fixed limiting rod 20. Through the arrangement of the second connecting block 15, the movable rod 16, the sleeve 17, the spring 18, the sliding block 19 and the limiting rod 20, firstly, the movable rod 16 is extended and retracted at one end of the sleeve 17, and at the same time, the sliding block 19 and the limiting rod 20 can cooperate with the arc groove 7, so that during the rotation of the Tai Chi fish-shaped plate 6, the support block 13 can synchronously complete the movement.

[0033] Furthermore, the other end of the spring 18 is welded to the surface of one end of the movable rod 16, and the sliding block 19 is slidably connected to the arc groove 7 through the limiting rod 20. Through the setting of the spring 18 and the elasticity of the spring 18, the support block 13 can also be moved when encountering an irregular reducer housing. The support block 13 cooperates with the clamping plate 1401 to fix the upper and lower positions of the reducer housing.

[0034] Furthermore, the locking mechanism 23 includes a connecting seat 2301, a first fixing bolt 2302, a second slider 2303, a trapezoidal block 2304, a second fixing bolt 2305 and a pushing block 2306. The connecting seat 2301 is placed on the upper surface of the fixing plate 21, and the first fixing bolt 2302 is passed through the surface of one side of the connecting seat 2301. The second slider 2303 is slidably connected to one end of the connecting seat 2301. The trapezoidal block 2304 is fixedly connected to one end of the second slider 2303. The second fixing bolt 2305 is passed through the surface of the one side of the connecting seat 2301. The pushing block 2306 is passed through one end of the second fixing bolt 2305. The movable block 2306 is set, and the connecting seat 2301 is placed on the surface of the fixed plate 21. The connecting seat 2301 is first fixed to the upper surface of the fixed plate 21 by connecting the first fixing bolt 2302 and the threaded groove 22. Then, it is only necessary to connect the second fixing bolt 2305 at the position of the adjacent threaded groove 22. During the locking process, the second fixing bolt 2305 will cause the pushing block 2306 to move downward, and at the same time, the pushing block 2306 will push the trapezoidal block 2304 to move. The trapezoidal block 2304 slides on one end of the connecting seat 2301 through the second slider 2303, and the side of the trapezoidal block 2304 will contact the side of the reducer housing. Under the locking of the second fixing bolt 2305, the trapezoidal block 2304 is tightly fitted with the side of the reducer housing to complete the fixation of the side position of the reducer housing.

[0035] Furthermore, the surface opening spacing of the connecting seat 2301 is consistent with the spacing between the thread grooves 22, and the pushing block 2306 is slidably connected to the trapezoidal block 2304. Through the setting of the pushing block 2306 and the trapezoidal block 2304, the slot position on one side of the pushing block 2306 is matched with the protruding position on one side of the trapezoidal block 2304, and the bevel structure on one side of the pushing block 2306 cooperates with the trapezoidal block 2304. As long as the pushing block 2306 is moved straight downward, the trapezoidal block 2304 can be pushed to move horizontally.

[0036] Furthermore, the thread grooves 22 are evenly spaced on the surface of the fixed plate 21. By setting the thread grooves 22 and multiple groups of thread grooves 22, the connecting seat 2301 can be conveniently fixed at different positions, and the connecting seat 2301 can be conveniently fixed at the position closest to the reducer housing.

[0037] Working principle: first, according to the bottom size of the reducer housing, the base 4 is driven to rotate by the driving motor 2, and the base 4 will drive the Tai Chi fish-shaped plate 6 to rotate. While the Tai Chi fish-shaped plate 6 rotates, the sliding block 19 will synchronously move at one end of the arc groove 7 through the limit rod 20. While the sliding block 19 moves, it will push the first slider 12 to move at one end of the guide rail 11. When at least one group of support blocks 13 above the first slider 12 can fit into the bottom position of the reducer housing, place the reducer housing on the upper surface of the support block 13, and at the same time, the side is against the splint 1401, and then continue to rotate the Tai Chi fish-shaped plate 6. At this time, the spring 18 under the support block 13 connected to the reducer housing will shrink, and the other support blocks 13 will continue to move until the three groups of support blocks 13 support the bottom of the reducer housing, and then rotate the screw 1406 backward to drive the splint 1401 to rotate upward, and then continue to rotate. The Tai Chi fish-shaped plate 6 allows the clamping plate 1401 to rotate downward to press the side surface of the reducer housing under the rotation push of the screw 1406. The locking screw 1406 allows the clamping plate 1401 to cooperate with the support block 13 to fix the upper and lower positions of the reducer housing. Subsequently, the connecting seat 2301 can be placed above the fixed plate 21, at a position close to the reducer housing. The connecting seat 2301 is first fixed to the upper surface of the fixed plate 21 by the first fixing bolt 2302, and then the second fixing bolt 2305 is passed through the top of the pushing block 2306. At the same time, the second fixing bolt 2305 passes through the connecting seat 2301 and is connected to the threaded groove 22. The second fixing bolt 2305 is rotated to press the pushing block 2306 downward. The pushing block 2306 will push the trapezoidal block 2304 to move forward until the trapezoidal block 2304 is completely in contact with the side of the reducer housing, thereby completing the locking and fixation of the reducer housing at different positions.

[0038] Obviously, the above embodiments are only examples for clear explanation, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention.
