Description

Technical Field

[0001] The utility model relates to the technical field of clamping fixtures, in particular to a clamping fixture for facilitating the clamping of batch processing parts. Background Art

[0002] A clamping fixture, usually simply referred to as a fixture, is an indispensable tool in machining, mainly used for fixing, positioning and supporting workpieces to ensure machining accuracy and stability. In general, one clamping fixture can only clamp one workpiece in sequence during use. However, for special workpieces, such as peelable gasket parts, due to their thin thickness, they are prone to deformation due to the pressure of the clamping fixture during single processing. Therefore, it is necessary to clamp multiple workpieces simultaneously to increase the thickness and prevent deformation and distortion due to the clamping force.

[0003] Therefore, a plate batch clamping device with the publication number of CN219005286U. First, a plurality of plates are stacked and placed between a first clamping plate and a second clamping plate along a second direction. Then, the first clamping plate is moved to both sides of the plate clamped by the first clamping plate and the second clamping plate. At this time, the first clamping plate is fixed by a fastening positioning pin. Subsequently, through a moving support, a moving abutting block connected to a screw rod is made to face the plate. By screwing the screw rod, the screw rod drives the moving abutting block to move towards a fixed abutting block. The moving abutting block gradually contacts the outer plate and applies a force to the stacked plurality of plates, so that the plurality of plates are gradually clamped and fixed by the fixed abutting block and the moving abutting block.

[0004] However, because the plurality of plates to be clamped are in a stacked state, there is no gap or the gap is small between the plates. Therefore, during the drilling process, the burrs at the hole ports have limited operating space due to the small gap during subsequent repair, so the cleaning effect of the burrs will be affected.

[0021] In order to more clearly understand the above objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0022] In the following description, many specific details are set forth to facilitate a thorough understanding of the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Such as Figures 1-4As shown in the figure, a clamping fixture for facilitating the clamping of batch processed parts includes a fixture 1. On both opposite sides of the tabletop of the fixture 1, limit frames 4 are inserted. The two limit frames 4 support the sides of the stacked plates. On one side between the two limit frames 4, a fixed plate 17 is fixedly connected, and on the other side, a pressing plate 2 is installed. The fixed plate 17 supports one side of the stacked plates, and the movement of the pressing plate 2 squeezes the other side of the stacked plates, so as to fix a number of stacked plates between the two limit frames 4. A sliding groove 19 is opened in the tabletop of the fixture 1. A sliding seat 6 is slidably connected in the sliding groove 19. Both sides of the sliding seat 6 are located at the sides of the two limit frames 4, and a tooth condition 5 is provided through one side of the sliding seat 6. One end of the tooth condition 5 is sleeved with a sliding frame 13 inserted in the limit frame 4. In the clamped state of the stacked plates, by moving the sliding seat 6, the tooth condition 5 drives the sliding frame 13 to slide in the limit frame 4 to the gap between two adjacent plates. A connecting frame 11 is inserted on one side of the sliding seat 6. On both sides of the connecting frame 11, gear shafts 14 meshed with the inner tooth surface of the tooth condition 5 are rotatably connected. One end of the gear shaft 14 extends and is inserted into the side of the sliding seat 6. An electric push rod 12 is connected between the connecting frame 11 and the sliding seat 6. During the movement of the limit frame 4, the electric push rod 12 contracts to drive the connecting frame 11 to drive the gear shaft 14 to descend and disengage from the tooth surface of the tooth condition 5. After the limit frame 4 fits the side of the plate, the connecting frame 11 rises again until the gear shaft 14 meshes with the tooth surface of the tooth condition 5. In addition, the side of the tooth condition 5 facing the plate in this solution is provided with an edge.

[0024] In addition: The contact part between the bottom edge of the limit frame 4 and the fixture 1 is T-shaped, and rack plates 7 are fixedly connected to both sides of the bottom edges of the two limit frames 1. The rack plates 7 are embedded in the tabletop of the fixture 1. The rack plates 7 on the same side of the two limit frames 4 are staggeredly distributed and the tooth surfaces face each other. A spur gear 8 meshed with the two tooth surfaces facing each other of the rack plates 7 is rotatably connected in the fixture 1. An electric telescopic rod 9 for driving one of the rack plates 7 to move is fixedly connected in the tabletop of the fixture 1. By the telescopic movement of the electric telescopic rod 9, the corresponding rack plate 7 drives the corresponding limit frame 4 to move synchronously. Under the meshing connection of the spur gear 8, the other rack plate 7 drives the other limit frame 4 to move synchronously, that is, the two limit frames 4 approach or move away from each other.

[0025] In addition: The top edge of the limit frame 4 is rotatably connected to a lead screw 3. A slider 10 inserted into the inner wall of the pressing plate 2 is threadedly connected to the lead screw 3. Since the slider 10 is inserted into the pressing plate 2, it will not rotate. Therefore, when the lead screw 3 rotates, it will drive the slider 10 to push the pressing plate 2 to move. When the other two limit frames 4 approach each other, they will also drive the lead screw 3 and the slider 10 to slide relative to the pressing plate 2. A threaded rod 15 is rotatably connected to the inside of the sliding groove 19 and threadedly penetrates through one side of the sliding seat 6. Motors 16 are installed on both the fixture 1 and the limit frame 4, and the motors 16 on the fixture 1 and the limit frame 4 are respectively used to drive the rotation of the threaded rod 15 and the lead screw 3. By using the motors 16 at the corresponding positions, the lead screw 3 or the threaded rod 15 at the corresponding position can be driven to rotate. One side of the fixed plate 17 facing the pressing plate 2 is connected by a spring rod to a movable plate 18 inserted into the inner wall of the limit frame 4. The provided movable plate 18 can, when the tooth condition 5 is inserted between the gaps of two adjacent plate members, push a part of the plate members to push the movable plate 18 to move against the elastic force of the spring rod, that is, to ensure that the two parts of the plate members can be smoothly separated to form a larger gap.

[0026] Working principle: Place the stacked plate members between the two limit frames 4 on the tabletop of the fixture 1, and the two limit frames 4 approach each other to fit the sides of the plate members. Then the pressing plate 2 moves to push the stacked plate members into contact with the movable plate 18. When deburring and repairing are required after the plate members are processed, the sliding seat 6 moves in the sliding groove 19 to between two adjacent plate members, and the tooth condition 5 is inserted between the two adjacent plate members by rotating the gear shaft 14. The elastic movement of the movable plate 18 provides a space for movement to increase the gap between two adjacent plate members, facilitating the deburring of the surface of the plate members.

[0027] The wiring diagrams of the electric telescopic rod 9, the electric push rod 12 and the motor 16 in the present utility model belong to the common knowledge in the art. Their working principles are already known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the electric telescopic rod 9, the electric push rod 12 and the motor 16 will not be explained in detail.

[0028] The above are only the preferred embodiments of the present utility model, and are not limitations on the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
