Description

Technical Field

[0001] The invention relates to the technical field of winch bracket manufacturing, in particular to a winch bracket processing fixture. Background Art

[0002] A winch is a common machine mainly used for reeling in and releasing cables, which mainly includes a belt shaft and a winch bracket, such as the winch bracket disclosed in Patent No. CN201183617Y. The winch bracket usually includes a base and two connecting parts. The bracket is provided with an axial hole, and the belt shaft is installed on the connecting part through the axial hole and can rotate. The connecting part on the existing winch bracket is an integrally formed hole. During installation and disassembly, the gear connected to the belt shaft needs to be removed, which is inconvenient for installation and disassembly. There is no restricting structure between the belt shaft and the connecting part. The gear or other restricting parts on the belt shaft need to conflict with the connecting part to achieve the restricting effect. When the belt shaft rotates, the belt shaft and the restricting parts thereon directly contact and rub with the connecting part, resulting in large wear and tear, easy damage, and short service life.

[0003] Based on this, the applicant considered designing a winch bracket that is easy to disassemble and assemble and can reduce wear. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is: how to provide a winch bracket that is easy to disassemble and assemble and can reduce wear.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] The winch bracket includes a bottom plate, a front branch and a rear branch arranged in front and back connected to the bottom plate, the front branch and the rear branch are respectively provided with mounting holes located on the same axis, and the inner side walls of the mounting holes are provided with limiting ring grooves;

[0007] The front branch and the rear branch both include a lower connecting block fixedly connected to the bottom plate and an upper connecting block detachably connected thereto; corresponding arc-shaped grooves are respectively provided on the top side of the lower connecting block and the bottom side of the upper connecting block to form the mounting hole when the upper connecting block is connected to the lower connecting block.

[0008] The working principle and advantages of the winch bracket of this technical solution are:

[0009] The front branch and rear branch arranged at the front and rear of the bottom plate of the winch bracket are used to connect with the belt shaft, and the inner side walls of the mounting holes opened on the front branch and the rear branch are provided with limiting ring grooves, and the belt shaft matched with this scheme is fixedly connected with convex rings corresponding to the limiting ring grooves at the front and rear. When the convex rings are used in conjunction with the limiting ring grooves, a limiting mechanism is formed, allowing the belt shaft to be stably rotatably installed on the winch bracket; and when the belt shaft rotates, only the convex ring on it contacts and rubs with the inner side wall of the limiting ring groove, which can reduce the wear of the winch bracket during use; and the arc grooves are formed on the upper connecting block and the lower connecting block of the above-mentioned mounting hole, and the upper connecting block and the lower connecting block are detachably connected. There is no need to remove the gears on the belt shaft during disassembly and installation, and installation and disassembly are very convenient.

[0010] Furthermore, the front branch and the rear branch both include supporting uprights and reinforcing uprights; the bottom of the supporting uprights is fixedly connected to the base plate, and the top is fixedly connected to the lower connecting block; the bottom of the reinforcing uprights is fixedly connected to the base plate, and the sides are fixedly connected to the side walls of the supporting uprights.

[0011] Furthermore, a plurality of protrusions are protruding from the bottom side of the bottom plate, and a first positioning hole penetrating the bottom plate and the protrusions is opened on the bottom plate.

[0012] Furthermore, a reinforcing rib fixedly connected to the protrusion is fixedly connected to the bottom side of the bottom plate.

[0013] A winch bracket processing fixture is used to process the above-mentioned winch bracket, which includes a fixed placement plate, and two arched pressing mechanisms arranged in front and behind are fixedly connected to the top side of the placement plate;

[0014] The arched clamping mechanism includes two spaced apart supporting vertical blocks and a crossbeam detachably connected to the two supporting vertical blocks. A clamping block groove is provided on the bottom side of the crossbeam. A concave clamping block is movably connected in the clamping block groove. A first locking piece is telescopically provided on the inner side wall of the concave clamping block.

[0015] The working principle and advantages of the winch bracket processing fixture of this technical solution are:

[0016] During the processing of the above-mentioned winch bracket, the precision requirements of the coaxially arranged mounting holes and the limiting ring grooves thereon are high. In order to prevent the winch bracket from being affected by the vibration during processing and affecting the processing precision of the winch bracket, the winch bracket needs to be locked by a processing fixture during processing. The processing fixture of this scheme is fixedly arranged at the processing location, and the winch to be processed is placed on the placement plate of the processing fixture, and then the front and rear branches arranged on the bottom plate are locked respectively by the arched clamping mechanisms arranged at the front and rear of the placement plate. The arched clamping mechanism makes When in use, first install the crossbeam on the two supporting vertical blocks, and the concave clamping block moves in the clamping block groove opened on the crossbeam. When the concave clamping block moves toward the winch bracket, the upper connecting blocks of the front branch and the rear branch are located in the concave clamping block, and the top side of the concave clamping block is abutted and locked with the top side of the upper connecting block. When the first locking piece arranged on the inner side wall of the concave clamping block is extended, it abuts and locks the side wall of the upper connecting block. The winch bracket is locked in multiple directions through the concave clamping block, thereby achieving the overall stability of the winch bracket when the mounting hole is processed, and the locking is simple and fast.
