Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, specifically relating to a special fixture for processing glue gun shells. Background Technology

[0002] The glue gun housing is the outermost main structural part of a hot melt glue gun, serving as its skeleton and skin, and providing safety protection. Glue guns using steel housings are not common; they are often used in large hot melt glue pumps on construction sites or in factory workshops. Because the glue gun housing is cylindrical and prone to rolling, these steel glue gun housings lack dedicated fixtures for subsequent finishing processes after casting. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a special fixture for processing glue gun shells, which can process three sides of a part at one time and realize the simultaneous processing of multiple parts.

[0004] To achieve the objective of this utility model, the technical solution adopted by this utility model is as follows: A special fixture for processing glue gun housings includes a rectangular base plate with multiple mounting units arranged horizontally side by side. Each mounting unit includes two parallel limiting grooves on the base plate, which extend through both sides of the base plate. The two sides of the glue gun housing can be fitted into the two limiting grooves. A positioning notch is provided on one side of the base plate between the two limiting grooves. A screw hole is provided on the base plate between the two limiting grooves, and a matching bolt is installed in the screw hole. The bolt can extend from the cavity of the glue gun housing and pass through a pressure plate.

[0005] Both ends of the limiting groove of this utility model are provided with a wider clearance groove.

[0006] The through hole for bolts to pass through in the pressure plate of this utility model is a T-shaped hole.

[0007] The base plate of this utility model has steps of the same width as the base plate at both ends of its back side.

[0008] The beneficial effects of this utility model are as follows: 1. By setting a limiting groove on the base plate that can just hold the glue gun housing, it is impossible for it to move on the horizontal surface. Then, by tightening with pressure plates and bolts, the glue gun housing is stably clamped. The upper surface and two end faces of the housing can be processed separately. At the same time, the side of the base plate is set with positioning notches to mark the drilling positions. Multiple mounting units are set on the base plate, which can process multiple parts at the same time.

[0009] 2. Wider clearance grooves are provided at both ends of the limiting groove to reduce the collision between the base plate and the glue gun housing, making the installation smoother. Attached Figure Description

[0017] To more clearly and in detail illustrate the objective technical solution of this utility model, the present utility model will be further described below through relevant embodiments. The following embodiments are merely illustrative of the implementation methods of this utility model and do not limit the scope of protection of this utility model. Example 1

[0018] like Figure 1 and Figure 2 As shown, a special fixture for processing glue gun housings includes a rectangular base plate 1. The base plate 1 has multiple mounting units 5 arranged horizontally side by side. Each mounting unit 5 includes two parallel limiting grooves 51 arranged on the base plate 1. The limiting grooves 51 penetrate through both sides of the base plate 1. The two sides of the glue gun housing 2 can be just locked into the two limiting grooves 51. A positioning notch 12 is provided on one side of the base plate 1 between the two limiting grooves 51. A screw hole 11 is opened on the base plate 1 between the two limiting grooves 51. A matching bolt is installed on the screw hole 11. The bolt 4 can extend from the cavity of the glue gun housing 2 and pass through a pressure plate 3. The glue gun housing 2 is fixed by fastening the bolt 4.

[0019] First, weld both ends of the base plate 1 to the machine tool. Then, clamp the two sides of the glue gun housing 2 onto the two limiting grooves 51 on the upper surface of the base plate 1. The length of the limiting grooves 51 is just enough to clamp the glue gun housing 2, preventing it from moving in the width direction of the base plate 1. Install bolts 4 on the screw holes 11 of the base plate 1. The bolts 4 pass upward through the inner cavity of the glue gun housing 2 and through the pressure plate 3. The nuts are located above the pressure plate 3. By tightening the bolts 4, the pressure plate 3 moves downward, pressing the glue gun housing 2 below, preventing it from detaching from the base plate 1. The glue gun housing 2 is stably clamped, and the upper surface and both ends of the housing can be machined separately. The positioning notches 12 on the base plate correspond to the drilling positions of the glue gun housing 2. Example 2

[0020] This embodiment is based on embodiment 1: like Figure 3 and Figure 4 As shown, both ends of the limiting groove 51 are provided with wider clearance grooves 13, which can reduce the collision with the glue gun housing 2 and enable smoother installation.

[0021] Both ends of the back of the base plate 1 are provided with steps 7 of the same width as the base plate 1. The addition of steps 7 enlarges the contact surface between the two ends of the base plate 1 and the machine tool, making the welding between the base plate 1 and the machine tool more secure. Example 3

[0022] like Figure 5 As shown, the through hole 31 of the pressure plate 3 through which the bolt 4 passes is a T-shaped hole.

[0023] Connection methods not mentioned in this utility model include welding, snap-fitting, riveting, hinge, threaded connection, or bonding.

[0024] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
