Description

Technical Field

[0001] The utility model relates to the technical field of clamping fixtures, in particular to a clamping fixture for assembling various heavy truck overhead cabinets. Background Technique

[0002] The heavy truck overhead cabinet is an important part of the heavy truck cab, mainly used to provide enclosed storage space and play the roles of storage and sunshade. Clamping fixtures play a key role in the assembly process of heavy truck overhead cabinets. They can ensure the precise positioning and stable clamping of components during the assembly process, thereby improving the assembly efficiency and quality.

[0003] However, the following problems exist in the existing clamping fixtures: When installing and stabilizing different overhead cabinets, they may not be well adapted to overhead cabinets of different sizes, which will affect the installation of larger or smaller overhead cabinets, resulting in low practicability of the fixture and affecting the installation of the overhead cabinet. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings in the existing technology that when installing and stabilizing different overhead cabinets, they may not be well adapted to overhead cabinets of different sizes, which will affect the installation of larger or smaller overhead cabinets, resulting in low practicability of the fixture and affecting the installation of the overhead cabinet, and to propose a clamping fixture for assembling various heavy truck overhead cabinets.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A clamping fixture for assembling various heavy truck overhead cabinets, including a cabinet body, a bottom plate and a top plate. The top plate is arranged directly above the bottom plate. Connection holes for connecting the fixture with equipment are opened at the four corners of the top plate. The cabinet body is placed on the side close to the top plate and the bottom plate. The top and bottom of the cabinet body are respectively attached to the sides close to the top plate and the bottom plate. A second soft pad for reducing the extrusion damage of the cabinet body is arranged at the bottom of the top plate;

[0007] A transverse clamping mechanism is arranged on the bottom plate for transversely clamping different overhead cabinets;

[0008] A vertical clamping mechanism is arranged between the top plate and the bottom plate for vertically clamping different overhead cabinets.

[0009] In a possible design, the lateral clamping mechanism includes a first rotating handle, a bidirectional lead screw, two sliding grooves, and two clamping plates. One side of the first rotating handle is fixedly connected to a first column. One end of the first column penetrates through one side of the bottom plate and is fixedly connected to one end of the bidirectional lead screw. The first column is rotatably connected to the bottom plate. A rectangular groove is formed in the top of the bottom plate. The two ends of the bidirectional lead screw are respectively rotatably connected to the inner walls of both sides of the same rectangular groove. A moving block is fixedly connected to the center of the bottom of each of the two clamping plates. The two moving blocks are both threadedly sleeved on the same bidirectional lead screw. Sliders are fixedly connected to both sides of the bottom of each of the two clamping plates. Two sliding grooves adapted to the sliders are formed in the top of the bottom plate. The two sliders are respectively slidably connected to the two sliding grooves. A first soft pad for reducing damage to the cabinet during clamping is provided on one side of each of the two clamping plates close to each other.

[0010] In a possible design, the vertical clamping mechanism includes a second rotating handle, a connecting rod, a threaded column, a connecting cylinder, four inner rods, four bottom cylinders, and four sliding rings. The top of the second rotating handle is fixedly connected to one end of the connecting rod. The other end of the connecting rod penetrates through the bottom of the bottom plate and is fixedly connected to the bottom end of the threaded column. The top end of the threaded column extends into the interior of the connecting cylinder. The connecting cylinder is threadedly sleeved on the threaded column. The top end of the connecting cylinder penetrates through the second soft pad and is fixedly connected to the bottom of the top plate. The bottoms of the four bottom cylinders are respectively fixedly connected to the four corners of the same bottom plate. The bottom ends of the four inner rods respectively extend into the interiors of the four bottom cylinders. The four sliding rings are respectively fixedly sleeved on the outer sides of the four inner rods. The four sliding rings are respectively slidably connected to the inner walls of the four bottom cylinders. The top ends of the four inner rods are respectively fixedly connected to the four corners of the top of the same top plate.

[0011] In a possible design, vertical blocks are fixedly connected to both sides of the top of the bottom plate. Two blocking rods for preventing interference of the rear side of the cabinet with the threaded column are fixedly connected to one side of each of the two vertical blocks close to each other. Sliding holes adapted to the blocking rods are formed in each of the two clamping plates and the two first soft pads. The two blocking rods are respectively slidably connected to the multiple sliding holes.

[0012] In a possible design, rotating columns are rotatably connected to both sides of the front side of the bottom plate. Limit blocks are fixedly sleeved on both of the two rotating columns. Bolt holes are formed in the front side of the bottom plate and on the two limit blocks. Fixing bolts are threadedly arranged in the bolt holes. The two limit blocks are fixedly connected to the bottom plate through the fixing bolts and the bolt holes. The top ends of the two limit blocks both extend to the front side of the cabinet.

[0013] In a possible design, a threaded hole is provided on the first rotating handle. A threaded rod is threadedly connected to the inner wall of the threaded hole. One end of the threaded rod is fixedly connected to a third rotating handle. A cross slot facilitating rotation is provided on the third rotating handle. The other end of the threaded rod is fixedly connected to a plug post for fixing the first rotating handle. A plurality of jacks adapted to the plug post are provided on one side of the bottom plate. A limiting ring preventing the threaded rod from detaching from the first rotating handle is fixedly sleeved on the plug post.

[0014] In this application, when it is necessary to install and stabilize the heavy truck top cabinet, the top plate is connected to the bottom of the device through the connection holes. Then, the operator places the heavy truck top cabinet on the bottom plate, between the top plate and the bottom plate. Subsequently, the operator rotates the first rotating handle. The first rotating handle drives the bidirectional lead screw to rotate in the rectangular slot through the first column. Since the two moving blocks are respectively threadedly sleeved on both ends of the bidirectional lead screw and their rotation is restricted by the cooperation of the sliders and the chutes, the rotation of the bidirectional lead screw will drive the two moving blocks to move towards or away from each other. When the two moving blocks move towards each other, they will drive the two clamping plates and the first soft pads installed on the inner sides of the clamping plates to clamp both sides of the heavy truck top cabinet, thereby achieving lateral stable clamping. Then, the operator rotates the second rotating handle. The second rotating handle drives the threaded column to rotate in the connecting cylinder through the connecting rod. Since the connecting cylinder is threadedly sleeved on the threaded column and the top end of the connecting cylinder is fixedly connected to the top plate, the rotation of the threaded column will cause the bottom plate to rise or fall relative to the top plate. After the bottom plate is lifted or lowered, the sides of the top plate and the bottom plate close to each other will perform vertical clamping on the heavy truck top cabinet, increasing its stability in the vertical direction. During the vertical clamping process, the inner rod slides in the bottom cylinder through the sliding ring to position the movement of the bottom plate and prevent the threaded column and the connecting cylinder from separating from each other. The setting of the blocking rod prevents the heavy truck top cabinet from interfering with the operation of the threaded column during the clamping process. The limiting block is fixedly connected to the bottom plate through the fixing bolt, and its top end extends to the front side of the heavy truck top cabinet, providing additional limiting and stability. When the heavy truck top cabinet is stably clamped by the lateral clamping mechanism, in order to prevent the clamping plates from accidentally loosening during subsequent operations, the operator can rotate the third rotating handle. The third rotating handle drives the threaded rod to rotate, causing the plug post to gradually approach and insert into the jacks on the bottom plate. The insertion of the plug post is restricted by the limiting ring to ensure that the threaded rod will not fall off from the first rotating handle, thereby locking the positions of the first rotating handle and the bidirectional lead screw and ensuring the stability of the clamping.

[0015] The beneficial effects of the present utility model are as follows:

[0016] In the present utility model, through the lateral clamping mechanism and the vertical clamping mechanism, the clamping and stabilization of top cabinets of different sizes are realized, and the all-round stable clamping of the heavy truck top cabinet during the assembly process is ensured, improving the processing accuracy and safety. At the same time, the provided soft pads effectively reduce the extrusion damage to the heavy truck top cabinet during the clamping process and protect the surface quality of the workpiece.
