Description

Technical Field

[0001] This utility model relates to the field of clamping fixtures, and in particular to an automatic clamping fixture for a new energy differential. Background Technology

[0002] In the leveling and clamping of the differential housing, multiple clamps are usually used to fix the housing. However, if a single cylinder is used to activate a single clamp, the clamping actions of each clamp are often difficult to synchronize completely during actual operation, and the clamping force applied by different clamps to the differential housing often varies, which has a certain impact on the accuracy and stability of the differential housing leveling work. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an automatic clamping fixture for new energy differentials, which solves the problems of difficulty in achieving complete synchronization of clamping actions and differences in clamping force caused by the traditional single cylinder starting a single clamp.

[0004] To address the problems in the existing technology, the technical solution of this utility model is as follows: An automatic clamping fixture for a new energy differential includes a base plate with multiple leveling blocks on the base plate and a through groove in the middle of the base plate. The multiple leveling blocks are arranged around the through groove on the bottom surface of the base plate, and the bottom of the leveling blocks is flat. A clamping component is provided on the base plate for each leveling block. The clamping component can be flipped toward the leveling block to clamp the differential housing flange. The base plate is also equipped with a synchronous drive mechanism, which is linked with multiple clamping components and can drive all clamping components to rotate synchronously to achieve synchronous clamping of the differential housing flange.

[0005] Optionally, the clamping assembly includes a slide rail fixed to the bottom surface of the base plate, a slide bar slidably disposed on the slide rail, a drive bar fixed to the bottom surface of the slide bar, an inclined bar rotatably connected to the drive bar, and a rotating shaft rotatably disposed on the bottom surface of the base plate. Torsion springs are sleeved at both ends of the rotating shaft. One end of the torsion spring is fixed to the outer wall of the rotating shaft, and the other end is fixed to the bottom surface of the base plate. A flipping pressure bar is fixed to the outer wall of the rotating shaft. The end of the inclined bar away from the drive bar is rotatably connected to the flipping pressure bar. The rotating shaft is located between the slide rail and the leveling block.

[0006] Optionally, the flipping pressure bar has a protrusion on the side away from the rotating shaft and close to the leveling block. The protrusion is semi-circular and made of hard rubber. The synchronous drive mechanism includes a segmented internal gear ring rotatably disposed on the outer ring of the bottom surface of the base plate. A worm gear reducer motor is fixed on the top surface of the base plate. The output end of the worm gear reducer motor passes through the base plate and is fixed with a gear. The gear meshes with the segmented internal gear ring. A pushing inclined block is provided on the inner wall of the segmented internal gear ring corresponding to each drive bar. The side of the pushing inclined block close to the axis of the base plate is an inclined surface. The end of the drive bar away from the axis of the base plate abuts against the inclined surface of the pushing inclined block.

[0007] Compared with the prior art, the advantages of this utility model are as follows: 1. This utility model sets up a segmented internal gear ring, a worm gear reducer motor, gears and multiple flipping pressure bars and drive bars in linkage. The worm gear reducer motor drives the gears to rotate, which can make the clamping action of each flipping pressure bar on the differential housing flange completely synchronized and with consistent force. This effectively solves the problem of asynchronous clamping action and different force caused by the traditional single cylinder starting a single clamp, and improves the accuracy and stability of the leveling work.

[0008] 2. This utility model provides a semi-circular protrusion made of hard rubber on the flip-over pressure strip. When the protrusion presses against the flange of the differential housing, it can ensure the pressing effect while avoiding hard contact with the outer wall of the differential housing, thus reducing damage to the housing and providing good protection.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figures 1 to 5 This embodiment provides an automatic clamping fixture for a new energy differential, including a base plate 1. A through groove 101 is provided in the middle of the base plate 1. A plurality of leveling blocks 2 are provided around the through groove 101 on the bottom surface of the base plate 1. The bottom of the leveling blocks 2 is flat.

[0017] During the flatness test, the flange of the differential housing to be tested is aligned with multiple flatness blocks 2, with the flange tightly against the bottom surface of the flatness blocks 2. Then, a clamping device is used to press it onto the flatness blocks 2 to complete the positioning work, so as to facilitate the subsequent flatness test of the top surface of the differential housing. The flatness test is existing technology, so it will not be described in detail here.

[0018] After the positioning is completed, a clamping operation is performed. On the bottom surface of the base plate 1, a slide rail 3 is fixed opposite to each leveling block 2. The length of the slide rail 3 is consistent with the radius of the bottom surface of the base plate 1. The leveling block 2 is located between the slide rail 3 and the axis of the base plate 1. A slide bar 4 is slidably provided on the outer wall of the slide rail 3. A drive bar 5 is fixed on the bottom surface of the slide bar 4. The end of the drive bar 5 near the leveling block 2 is rotatably connected to the inclined bar 6 through a shaft pin. A rotating shaft 7 is also rotatably connected to the bottom surface of the base plate 1 opposite to each leveling block 2 through a bearing. The rotating shaft 7 is located between the slide rail 3 and the leveling block 2. A flipping pressure bar 8 is fixed on the outer wall of the middle part of the rotating shaft 7. The end of the inclined bar 6 away from the drive bar 5 is rotatably connected to the outer wall of the flipping pressure bar 8 through a shaft pin. By pushing and pulling the drive bar 5, the inclined bar 6 is moved, thereby pushing the flipping pressure bar 8 to flip.

[0019] After the differential housing is placed, push the drive bar 5 towards one side of the axis of the base plate 1. This will push the flipping pressure bar 8 to flip towards the differential housing. In order to ensure that the flange of the differential housing is pressed tightly, a semi-circular protrusion 9 is fixed on the side of the flipping pressure bar 8 away from the rotating shaft 7 and close to the leveling block 2. After the flipping pressure bar 8 is pushed to flip, the protrusion 9 presses against the flange of the differential housing and presses it against the leveling block 2. This ensures that all the flipping pressure bars 8 flip and press at the same time, thus ensuring the consistency of the pressing force.

[0020] To ensure consistent clamping force, a segmented internal gear ring 10 is rotatably mounted on the outer ring of the bottom surface of the base plate 1. The segmented internal gear ring 10 has teeth only within a certain angular range. A worm gear reducer motor 11 is fixed to the top surface of the base plate 1. The protruding end of the worm gear reducer motor 11 extends through the base plate 1 to its lower part and is fixed with a gear 12. The gear 12 meshes with the segmented internal gear ring 10. A pushing wedge 13 is fixed to the inner wall of the segmented internal gear ring 10, directly opposite each drive bar 5, to push... The inclined block 13 is set at an angle on one side near the axis of the base plate 1, and the multiple drive bars 5 are of different lengths and are adapted to the position of the inspection block 2. However, it is ensured that the end of all drive bars 5 away from the axis of the base plate 1 is in contact with the inclined surface of the pusher 13 directly opposite it. The contact force comes from the torsion springs 14 sleeved on both ends of the rotating shaft 7. One end of the torsion spring 14 is fixed to the outer wall of the rotating shaft 7, and the other end is fixed to the outer wall of the bottom surface of the base plate 1, thereby providing the power for the flipping pressure bar 8 to flip away from the inspection block 2.

[0021] When all the flipping pressure bars 8 need to be flipped and clamped simultaneously, the worm gear reducer motor 11 is driven to work, which drives the gear 12 to rotate and rotates the segmented internal gear ring 10. This causes all the pushing inclined blocks 13 to rotate around the axis of the base plate 1 at the same time, pushing the drive bar 5 to perform synchronous clamping work, thus ensuring the consistency of clamping. The protrusion 9 can be made of hard rubber to avoid damage caused by hard contact with the outer wall of the differential housing.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
