Technical Field

[0001] This utility model relates to the field of brush manufacturing, and in particular to a pressure fixture for bonding and washing double-sided brushes. Background Technology

[0002] Washing brush double sheets are materials used in the preliminary process of making washing machine motor brushes. They are formed by placing a piece of tape on a single brush sheet and then laying another single brush sheet flat.

[0003] Currently, during the manufacturing of double-blade washing brushes, defective products are produced due to poor adhesion between the two brush layers, as well as misalignment of the two brush layers caused by factors such as the thickness and shape of the individual brush blades. This results in production waste and increased costs. Utility Model Content

[0004] This utility model provides a pressure fixture for bonding two wash brush plates, which aims to solve the problems of weak bonding and misalignment of the two brush plates during the manufacturing process.

[0005] This utility model provides a pressure fixture for bonding two wash brush blades. The pressure fixture includes: a frame, which includes a base plate and three side plates that are perpendicularly adjacent to each other on the base plate; a top plate for mounting onto the frame after several wash brush blades are stacked inside the frame, which is perpendicular to the base plate and detachably connected to two of the three side plates; and a cover plate for mounting onto the frame after several wash brush blades are stacked inside the frame, which is opposite to the base plate and detachably connected to at least two of the three side plates; wherein the surface of the cover plate facing the base plate has a step that can be recessed into the frame, and after the top plate is mounted onto the frame, pressure is applied to the wash brush blades inside the frame through the step of the cover plate.

[0006] Preferably, the top plate has a step on the side facing the interior of the frame that can be recessed into the frame.

[0007] Preferably, the three side plates are integrally formed with the base plate, or the three side plates are fixedly installed on the base plate.

[0008] Preferably, the top plate is connected to two of the three parallel side plates by bolts.

[0009] Preferably, the cover plate is bolted to at least two of the three side plates.

[0010] Preferably, the pressurizing fixture adopts an integrated frame.

[0011] This utility model provides a pressure fixture for bonding two washing brush plates. The top plate restricts the movement of the two layers of brushes within the frame, reducing misalignment. At the same time, the steps of the cover plate apply pressure to the two washing brush plates within the frame, making the two layers of brushes bond more firmly. This significantly improves product yield, reduces production waste, and lowers production costs. Attached Figure Description

[0017] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0018] See Figures 1 to 4 The pressure fixture for bonding two wash brush blades of this utility model may include: frame 1, cover plate 2, and top plate 3.

[0019] See Figure 1 The frame 1 includes a base plate 12 and three side plates 11 arranged vertically adjacent to each other on the base plate. The three side plates 11 can be integrally formed with the base plate 12, or they can be fixedly installed on the base plate 12 by means of connectors including bolts, expansion tubes, and nuts, or they can be fixedly installed on the base plate 12 by physical structures such as clips and slide rails. In addition, the three side plates 11 are provided with several through holes to allow for venting during subsequent heat treatment.

[0020] See Figure 2The top plate 3 is perpendicular to the bottom plate 12 and detachably connected to two of the three side plates 11 that are parallel to each other. Specifically, the detachable connection is a bolt connection. More specifically, each of the two parallel side plates 11 has a positioning hole for fixing the top plate 3, which mates with the bolt holes on both sides of the top plate 3. Thus, after several double-blade washing brushes are stacked inside the frame 1, the top plate 3 can be installed on one side of the frame 1 using fixing bolts, limiting the position of the double-blade washing brushes inside the frame 1. That is, after receiving bolt pressure, the double-blade washing brushes inside the frame 1 are fixed and restricted. In a preferred embodiment, the surface of the top plate 3 facing the inside of the frame 1 has a step that can be recessed into the frame 1, further restricting the horizontal position of the double-blade washing brushes inside the frame 1 and reducing misalignment of the two layers of brushes.

[0021] See Figure 3 The cover plate 2 is opposite to the base plate 12 and is detachably connected to at least two of the three side plates 11, specifically by bolt connection. Specifically, at least two of the side plates 11 have positioning holes for fixing the cover plate 2, which mate with bolt fixing holes on both sides of the cover plate 2. Thus, after several double-blade washing brushes are stacked inside the frame 1, the cover plate 2 can be installed on the frame 1 using fixing bolts 4. Furthermore, the middle portion of the surface of the cover plate 2 facing the base plate 12 has a slightly raised step that can be recessed into the frame 1. After the cover plate 2 is installed on the frame 1, under the tightening action of the fixing bolts 4, the step of the cover plate 2 applies pressure to the double-blade washing brushes inside the frame 1, i.e., the pressure is stably applied to the double-blade washing brushes inside the frame 1. In addition, the cover plate 2 is provided with several through holes to allow for venting during subsequent heat treatment, and several rings are installed on the surface of the cover plate 2 away from the interior of the frame 1. Figure 2 There are two in the middle to facilitate handling and movement.

[0022] The pressure-applying fixture of this utility model only includes the frame, the cover plate, the top plate, and the fixing bolts. The structure is simple and reasonable. In addition, this utility model uses the cover plate installed on the frame to apply stable pressure to the double-blade brush products inside the frame to enhance the bonding firmness. The top plate installed on one side of the frame restricts the displacement of the double-blade brush products inside the frame, reducing misalignment of the two blades. Based on the above measures, the accuracy and stability of product bonding can be guaranteed, the product yield can be improved, the production efficiency can be increased, the production waste can be reduced, and the production cost can be lowered.

[0023] Furthermore, the pressure fixture of this utility model can adopt an integrated frame, which greatly reduces misalignment defects caused by uneven fixture top and bottom, further improves product yield, increases production efficiency, reduces production waste, and lowers production costs.

[0024] The method of using the pressure fixture for bonding and washing double-bladed electric brushes of this utility model is as follows:

[0025] Step 1: With the frame 1 and the cover plate 2 fixed by screws (bolts), loosen the fixing screws (fixing bolts 4) of the cover plate 2.

[0026] Step 2: Lay the brush sheet flat in one direction inside the frame 1, place a piece of tape on top of the brush sheet, and then lay another brush sheet flat to form a double washing brush.

[0027] Step 3: Repeat step 2 several times, for example, ten times, to ensure that the double-piece washing brush is completely stacked inside frame 1.

[0028] Step 4: Cover with the cover plate 2, then cover with the top plate 3. Use fixing bolts to install the top plate 3 on the side plate 11 of the frame 1 and tighten the fixing bolts to restrict the horizontal position of the double washing brush products inside the frame 1, that is, to restrict the movement of the products in the horizontal direction and ensure the accuracy of the bonding of the double washing brush products.

[0029] Step 5: Install the cover plate 2 on top of the frame 1 using the fixing bolts 4. Specifically, a torque wrench can be used to tighten the fixing bolts 4 of the cover plate 2 to the specified pressure. That is, the cover plate 2, through the cooperation of the fixing bolts 4 and the torque wrench, applies stable pressure to the double-blade washing brush inside the frame 1. This completes the product loading.

[0030] The preferred embodiments of this utility model have been described above with reference to the accompanying drawings, but this does not limit the scope of the utility model. Any modifications, equivalent substitutions, and improvements made by those skilled in the art without departing from the scope and essence of this utility model should be within the scope of the utility model.
