Description
Technical Field
[0001] The utility model relates to the technical field of motor seat polishing, and more specifically to a positioning mechanism for motor seat polishing. Background Art
[0002] The motor seat is a component used to fix and install the motor. The shapes of the motor seat are relatively diverse, among which the most common is the rectangular motor seat. During production, the rectangular motor seat usually needs to be polished. During the polishing operation of the rectangular motor seat, a positioning structure is required to clamp and fix it.
[0003] The existing positioning structure usually only serves to clamp and fix the motor seat. After the motor seat is fixed, over-polishing is likely to occur when the grinding disc polishes the motor seat, which will cause a large change in the thickness of the motor seat. If the motor seat has high requirements for dimensional accuracy, the large change in the thickness of the motor seat can easily affect its installation and use in the equipment. In view of this, we propose a positioning mechanism for polishing the motor seat. Utility Model Content
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a positioning mechanism for polishing a motor seat to solve the technical problem that the current positioning structure is not convenient for accurately controlling the polishing thickness of the motor seat.
[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a positioning mechanism for polishing a motor seat, comprising a base, two groups of symmetrical clamping structures slidably arranged on both sides of the top of the base, symmetrical welding blocks arranged in the center of both sides of the top of the base, and electric hydraulic push rods arranged on opposite sides of the two groups of welding blocks, the piston ends of the electric hydraulic push rods are connected to the clamping structures, positioning structures are movably arranged on the front and rear sides of the two groups of welding blocks on the base, the positioning structures are movably connected to the clamping structures, and an adjustment structure is arranged on the top of the welding blocks, and the adjustment structure is movably connected to the positioning structure;
[0006] The adjustment structure includes a screw, a screw sleeve and a third limiting rod. The screw does not rotate to the top of the welding block. The screw sleeve is arranged on the screw. The third limiting rod is symmetrically arranged on the front and rear sides of the screw sleeve. The third limiting rod is movably connected to the positioning structure.
[0007] The utility model is designed with a positioning structure and an adjusting structure. When the rectangular motor seat is placed on the base, the clamping structure is synchronously driven by the electric hydraulic push rod to clamp and position the motor seat. At this time, the clamping blocks on the two sets of clamping structures drive the positioning structure to move back and forth when moving, so that the positioning structure synchronously clamps the rectangular motor. Then, the height of the positioning bar in the positioning structure can be directly adjusted through the adjusting structure. The top surface of the positioning bar should be kept lower than the top surface of the motor seat. At this time, the distance between the top surface of the positioning bar and the top surface of the motor seat is the polishing thickness. Therefore, the polishing thickness of the top surface of the motor seat can be accurately controlled, thereby avoiding the occurrence of over-polishing and ensuring that the dimensional accuracy of the motor seat after polishing meets the use requirements. The adjusting structure of the utility model is The screw rod, the screw sleeve and the third limit rod are composed of a screw rod, a screw sleeve and a third limit rod, and the third limit rod passes through the positioning strip, so the positioning strip can be freely displaced forward and backward on the third limit rod, so as not to affect the clamping structure driving the positioning structure to clamp the motor seat. Conversely, the screw sleeve and the third limit rod are limited so that they will not rotate. Therefore, when the screw rod is turned, the screw sleeve will be vertically lifted and lowered, and then the screw sleeve can synchronously realize the lifting and lowering control of the two sets of positioning strips through the two sets of third limit rods, which can conveniently complete the height adjustment of the two sets of positioning strips and ensure that the height of the two sets of positioning strips is equal without deviation, that is, it can ensure that the distance between the two sets of positioning strips in front and behind the motor seat and the top surface of the motor seat is the same, avoiding deviation, thereby further ensuring the accuracy of controlling the polishing thickness of the motor seat.
[0008] Preferably, the clamping structure includes a supporting bar, which is slidably arranged on the base. An open groove is provided on one side of the supporting bar, and opposing screw rods are rotatably arranged inside the open groove. Two groups of mounting blocks are symmetrically arranged on the opposing screw rods, and a clamping block is arranged on one side of the mounting block outside the open groove. A driving motor is arranged at one end of the supporting bar, and the rotating shaft of the output end of the driving motor is connected to the opposing screw rod.
[0009] Preferably, symmetrical T-shaped sliding grooves are provided on the front and rear sides of the top of the base, and a T-shaped slider is slidably arranged inside the T-shaped sliding groove, and the T-shaped slider is connected to the supporting bar.
[0010] Preferably, the positioning structure includes a mounting bar, which is movably arranged on the welding block and movably docked with the clamping block. Second limiting rods are arranged at both ends of the top of the mounting bar, and a positioning bar is movably arranged on the second limiting rod, and the third limiting rod passes through the positioning bar.

[0012] Preferably, a groove is provided at the bottom of the mounting bar, and a matching block is slidably arranged inside the groove, and the matching block is connected to the clamping block.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] 1. The positioning structure and adjustment structure designed in the present invention are such that when the rectangular motor seat is placed on the base, the clamping structure is synchronously driven by the electric hydraulic push rod to clamp and position the motor seat. At this time, the clamping blocks on the two sets of clamping structures drive the positioning structure to move back and forth when moving, so that the positioning structure synchronously clamps the rectangular motor. Then, the height of the positioning bar in the positioning structure can be directly adjusted through the adjustment structure. The top surface of the positioning bar should be kept lower than the top surface of the motor seat. At this time, the distance between the top surface of the positioning bar and the top surface of the motor seat is the polishing thickness. Therefore, the polishing thickness of the top surface of the motor seat can be accurately controlled, thereby avoiding over-polishing, ensuring that the dimensional accuracy of the motor seat after polishing meets the use requirements, and solving the technical problem that the current positioning structure is not convenient for accurately controlling the polishing thickness of the motor seat. Therefore, the present invention has the advantage of accurately controlling the polishing thickness of the motor seat.
[0015] 2. The adjustment structure of the present invention is composed of a screw, a screw sleeve, and a third limit rod. The third limit rod passes through the positioning strip, so the positioning strip can be freely displaced forward and backward on the third limit rod, thereby not affecting the clamping structure and driving the positioning structure to clamp the motor seat. Conversely, the screw sleeve and the third limit rod are limited so that they will not rotate. Therefore, when the screw is turned, the screw sleeve will be vertically lifted and lowered, and then the screw sleeve can synchronously realize the lifting and lowering control of the two groups of positioning strips through the two groups of third limit rods, which can conveniently complete the height adjustment of the two groups of positioning strips and ensure that the heights of the two groups of positioning strips are equal without deviation, that is, it can ensure that the distances between the two groups of positioning strips in front and behind the motor seat and the top surface of the motor seat are the same, avoiding deviation, thereby further ensuring the accuracy of controlling the polishing thickness of the motor seat.

[0022] like Figures 1 to 4 As shown, the utility model relates to a positioning mechanism for polishing a motor seat, comprising a base 1, two groups of symmetrical clamping structures 4 are slidingly arranged on both sides of the top of the base 1, symmetrical welding blocks 2 are arranged in the center of both sides of the top of the base 1, and electric hydraulic push rods 3 are arranged on the opposite sides of the two groups of welding blocks 2, the piston ends of the electric hydraulic push rods 3 are connected to the clamping structures 4, and positioning structures 5 are movably arranged on the front and rear sides of the two groups of welding blocks 2 on the base 1, the positioning structure 5 is movably connected to the clamping structure 4, and an adjustment structure 6 is arranged on the top of the welding block 2, and the adjustment structure 6 is movably connected to the positioning structure 5. When the rectangular motor seat is placed on the base 1, it is synchronously driven by the electric hydraulic push rods 3 After the clamping structure 4 clamps and positions the motor seat, the clamping blocks 405 on the two groups of clamping structures 4 drive the positioning structure 5 to move forward and backward when moving, so that the positioning structure 5 synchronously clamps the rectangular motor, and then the height of the positioning bar 504 in the positioning structure 5 can be directly adjusted through the adjustment structure 6. The top surface of the positioning bar 504 must be kept lower than the top surface of the motor seat. At this time, the distance between the top surface of the positioning bar 504 and the top surface of the motor seat is the polishing thickness. Therefore, the polishing thickness of the top surface of the motor seat can be precisely controlled, thereby avoiding excessive polishing and ensuring that the dimensional accuracy of the motor seat after polishing meets the requirements of use.
[0023] Specifically, the clamping structure 4 includes a supporting bar 401, which is slidably arranged on the base 1. An open groove 406 is provided on one side of the supporting bar 401, and a counter screw rod 403 is rotatably arranged inside the open groove 406. Two groups of mounting blocks 404 are symmetrically arranged on the counter screw rod 403, and a clamping block 405 is arranged on one side of the mounting block 404 outside the open groove 406. A driving motor 402 is arranged at one end of the supporting bar 401, and the rotating shaft of the output end of the driving motor 402 is connected to the counter screw rod 403. After the two groups of supporting bars 401 clamp the two ends of the motor base, the counter screw rod 403 can be driven to rotate by the driving motor 402, and then the two groups of mounting blocks 404 on the counter screw rod 403 drive the two groups of clamping blocks 405 to move relative or opposite to each other synchronously, thereby achieving clamping and fixation of the front and back of the motor base, thereby completing the positioning of the motor base.
[0024] Furthermore, symmetrical T-shaped grooves 101 are provided on the front and rear sides of the top of the base 1, and a T-shaped slider 102 is slidingly arranged inside the T-shaped groove 101. The T-shaped slider 102 is connected to the supporting bar 401. With the cooperation of the T-shaped groove 101 and the T-shaped slider 102, the sliding installation of the supporting bar 401 is realized.
[0025] Furthermore, the positioning structure 5 includes a mounting bar 501, which is movably arranged on the welding block 2, and the mounting bar 501 is movably connected to the clamping block 405. Second limiting rods 503 are arranged at both ends of the top of the mounting bar 501, and a positioning bar 504 is movably arranged on the second limiting rod 503, and a third limiting rod 603 passes through the positioning bar 504; first limiting rods 502 are inserted into both ends of the front side of the mounting bar 501, and the first limiting rod 502 is connected to the welding block 2; a groove 505 is opened at the bottom of the mounting bar 501, and a matching rod 505 is slidably arranged inside the groove 505. Block 506, and the matching block 506 is connected to the clamping block 405. With the cooperation of the first limit rod 502, the forward and backward movable installation of the positioning structure 5 can be realized. With the cooperation of the groove 505 and the matching block 506, when the clamping block 405 moves left and right with the supporting strip 401, the positioning structure 5 and the clamping block 405 will not be affected. Moreover, when the clamping block 405 moves forward and backward, with the cooperation of the groove 505 and the matching block 506, the entire positioning structure 5 can be driven to move forward and backward at the same time, so that the positioning structure 5 can clamp the motor base together with the clamping block 405.
[0026] In an embodiment of the present invention, the adjustment structure 6 includes a screw 601, a screw sleeve 602 and a third limiting rod 603. The screw 601 does not rotate to the top of the welding block 2. The screw sleeve 602 is arranged on the screw 601. The third limiting rod 603 is symmetrically arranged on the front and rear sides of the screw sleeve 602. The third limiting rod 603 is movably connected to the positioning structure 5. When the positioning structure 5 moves forward and backward, the positioning bar 504 can move freely forward and backward on the third limiting rod 603 without affecting the forward and backward displacement of the two groups of positioning structures 5. Conversely, the screw sleeve 602 and the third limiting rod 603 can be adjusted. The limit prevents it from rotating. Therefore, when the screw 601 is turned, the screw sleeve 602 will be vertically lifted and lowered, and then the screw sleeve 602 can synchronously realize the lifting and lowering control of the two groups of positioning bars 504 through two groups of third limiting rods 603, which can conveniently complete the height adjustment of the two groups of positioning bars 504 and ensure that the heights of the two groups of positioning bars 504 are equal without deviation, that is, it can ensure that the distance (polishing thickness) between the two groups of positioning bars 504 in front and behind the motor seat and the top surface of the motor seat is the same, avoiding deviation, thereby further ensuring the accuracy of controlling the polishing thickness of the motor seat.
[0027] Working principle: This embodiment provides a positioning mechanism for polishing a motor seat. First, when the rectangular motor seat is placed on the base 1, the electric hydraulic push rod 3 synchronously drives the clamping structure 4 to clamp and position the motor seat. At this time, the clamping blocks 405 on the two sets of clamping structures 4 drive the positioning structure 5 to move back and forth during movement, so that the positioning structure 5 synchronously clamps the rectangular motor. Then, the height of the positioning bar 504 in the positioning structure 5 can be directly adjusted through the adjustment structure 6. The top surface of the positioning bar 504 must be kept lower than the top surface of the motor seat. At this time, the distance between the top surface of the positioning bar 504 and the top surface of the motor seat is the polishing thickness. Therefore, the polishing thickness of the top surface of the motor seat can be accurately controlled, thereby avoiding the occurrence of over-polishing and ensuring that the dimensional accuracy of the motor seat after polishing meets the use requirements.
[0028] Secondly, when the positioning structure 5 moves forward and backward, the positioning bar 504 can move freely forward and backward on the third limiting rod 603 without affecting the forward and backward displacement of the two groups of positioning structures 5. On the contrary, it also limits the screw sleeve 602 and the third limiting rod 603 so that they will not rotate. Therefore, when the screw rod 601 is turned, the screw sleeve 602 will be vertically lifted and lowered, and then the screw sleeve 602 can synchronously realize the lifting and lowering control of the two groups of positioning bars 504 through the two groups of third limiting rods 603, which can conveniently complete the height adjustment of the two groups of positioning bars 504 and ensure that the height of the two groups of positioning bars 504 is equal without deviation, that is, it can ensure that the distance (polishing thickness) between the two groups of positioning bars 504 in front and behind the motor seat and the top surface of the motor seat is the same, avoiding deviation, thereby further ensuring the accuracy of controlling the polishing thickness of the motor seat.
