Description

Technical Field

[0001] This utility model belongs to the field of clamping technology and relates to a crystal lever head coating clamp. Background Technology

[0002] When coating the crystal dial head, it is necessary to clamp the crystal dial head stably. The upper surface of the crystal dial head is an irregular plane, so when coating the upper surface, it is necessary to clamp the crystal dial head tightly and expose the upper surface of the crystal dial head. Currently, a clamp is usually used to clamp the crystal dial head.

[0003] Existing fixtures, such as the Chinese patent application [Authorization Announcement No.: CN220823397U], disclose a placement machine fixture with good positioning effect, including a base, a mounting seat fixedly mounted on the top of the base, a positioning rod fixedly mounted on the top of the mounting seat, a placement plate provided on the top of the mounting seat, a positioning groove opened on the top of the placement plate, a positioning block fixedly mounted on the back of the mounting seat, a fixing rod fixedly mounted on the inner wall of the positioning block, a connecting block rotatably connected to the outer edge of the fixing rod, a pressure plate fixedly mounted on the top of the connecting block, a pressure strip fixedly mounted on the inner wall of the pressure plate, a placement groove opened on the top of the mounting seat, an electric push rod fixedly mounted on the inner wall of the placement groove, a slot opened on the top of the pressure plate, and a square block fixedly mounted on the front of the base, a connecting ring rotatably connected to the inner wall of the square block.

[0004] In the above structure, a placement plate is provided on the top of the mounting base, a positioning groove is opened on the top of the placement plate, and a pressure strip is fixedly assembled on the inner wall of the pressure plate. By placing the workpiece in the placement plate and pressing the workpiece onto the base by the pressure strip, the workpiece is positioned. However, for the crystal lever head in this application, the upper surface and side wall are irregular planes when positioning, so the positioning of the crystal lever head in the positioning groove is unstable. Furthermore, when pressed by the pressure strip, the upper surface of the crystal lever head cannot be fully exposed, which is inconvenient for coating processing on the upper surface of the crystal lever head and reduces the positioning stability of the fixture. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a crystal lever head coating fixture. The technical problem this invention aims to solve is: how to address the issue of low stability in workpiece positioning of existing fixtures.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A crystal lever head coating fixture includes a base plate, on which at least one strip-shaped fixing part is provided. The fixing part has multiple positioning grooves with openings at their upper ends. The multiple positioning grooves are distributed sequentially at intervals along the length of the fixing part. One side wall of each positioning groove is close to the outer wall of the fixing part, and a positioning opening is provided on this side wall, extending laterally through the side wall of the positioning groove. The coating fixture also includes a positioning pressure strip, on which adhesive tape is adhered. The positioning pressure strip presses against the side wall of the fixing part and covers the positioning opening. The positioning pressure strip is connected to the base plate.

[0008] Place the crystal shifter head in the positioning groove, and then press the positioning strip onto the side wall of the fixing part. To improve the positioning effect of the positioning strip, tape is pasted on the side wall of the positioning strip. The positioning strip is pressed tightly against the side wall of the fixing part and covers the positioning opening. The tape of the positioning strip can adhere to the side wall of the crystal shifter head located in the positioning groove. Then, the positioning strip is connected to the base plate. Thus, the positioning strip and the side wall of the positioning groove are used to position the two side walls of the crystal shifter head. Since the upper surface and the outer side wall of the crystal shifter head are irregular surfaces, it is easier to limit the outer side wall of the crystal shifter head by pressing and adhering, thereby improving the positioning effect of the crystal shifter head.

[0009] In the aforementioned crystal lever head coating fixture, the positioning strip has a waist-shaped positioning hole along the width direction of the fixing part, and the positioning strip is positioned on the base plate by fasteners passing through the positioning hole.

[0010] By providing waist-shaped positioning holes on the positioning strip, the positioning pressure strip can move along the width direction of the fixing part. This allows the crystal lever head to be positioned by adhesion and compression when it protrudes from the positioning groove along the width direction of the fixing part. This provides a good positioning effect for crystal lever heads of different sizes, improving the versatility and stability of the fixture.

[0011] In the above-mentioned crystal lever head coating fixture, the side wall of the fixing part is planar, and the side wall of the positioning strip is in contact with the side wall of the fixing part.

[0012] Normally, the crystal dial head is pressed into the positioning groove. By fitting the positioning strip and the fixing part together, the contact area between the positioning strip and the fixing part is increased, thus improving the positioning effect.

[0013] In the above-mentioned crystal lever head coating fixture, the two ends of the base plate have pre-positioning portions that are strip-shaped along the width direction of the fixing portion. Limiting steps are provided on the lower bottom wall of both ends of the positioning pressure strip. The pre-positioning portion is embedded in the limiting step. The limiting step abuts against the pre-positioning portion along the length direction of the positioning pressure strip. A fixing hole is provided on the pre-positioning portion. The positioning hole is provided on the limiting step.

[0014] During the installation of the positioning strip, the positioning strip is placed on the pre-positioning part. At this time, the pre-positioning part is embedded in the limiting step of the positioning strip, so that both ends of the positioning strip are positioned by the pre-positioning part and the pre-positioning of the limiting step. Then, the positioning strip is fixed on the pre-positioning part by fasteners, which improves the positioning efficiency and positioning effect.

[0015] In the aforementioned crystal lever head coating fixture, the sidewall of the limiting step is in contact with the fixing part along the width direction of the fixing part.

[0016] By having the side wall of the limiting step fit snugly against the fixing part, the positioning effect of the limiting step is improved, thereby further enhancing the positioning effect.

[0017] In the above-mentioned crystal lever head coating fixture, the base plate has strip-shaped limiting parts on both sides, the limiting parts are arranged parallel to the fixing parts, and the positioning pressure strip can be disposed between the limiting parts and the fixing parts.

[0018] By setting the limiting part, it is possible to prevent the positioning strip from sliding out of the base plate when it slides along the width direction of the fixing part, thereby improving the stability of the installation and positioning.

[0019] In the above-mentioned crystal lever head coating fixture, there are two fixing parts. There is a clearance space between the fixing part and the limiting part and between the two adjacent fixing parts, which allows the positioning pressure strip to slide along the width direction of the fixing part.

[0020] By providing clearance, the positioning strip has room to slide, which further facilitates the adjustment of the positioning strip's position and improves positioning efficiency.

[0021] Compared with existing technologies, this crystal shifter head coating clamp has the following advantages: Adhesive tape is pasted on the side wall of the positioning strip, the positioning strip is pressed tightly against the side wall of the fixing part and covers the positioning opening, the adhesive tape of the positioning strip can adhere to the side wall of the crystal shifter head located in the positioning groove, and then the positioning strip is connected to the base plate. Therefore, the positioning strip and the side wall of the positioning groove are used to position the two side walls of the crystal shifter head. Since the upper surface and the outer side wall of the crystal shifter head are irregular surfaces, the positioning effect of the crystal shifter head is improved by pressing and bonding.

Detailed Implementation

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] like Figure 1 As shown, the crystal lever head coating fixture includes a base plate 1, on which at least one strip-shaped fixing part 11 is provided, and the fixing part 11 is provided with a plurality of positioning grooves 11a with upper openings.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, multiple positioning grooves 11a are distributed sequentially at intervals along the length of the fixing part 11. The groove wall on one side of the positioning groove 11a is close to the outer wall of the fixing part 11, and a positioning opening 11a1 is provided on the groove wall that penetrates the side wall of the positioning groove 11a laterally. This coating fixture includes a positioning pressure strip 2. Adhesive tape 5 is pasted on the side wall of the positioning pressure strip 2. The positioning pressure strip 2 presses on the side wall of the fixing part 11 and covers the positioning opening 11a1. The positioning pressure strip 2 has a waist-shaped positioning hole 21 along the width direction of the fixing part 11. The positioning pressure strip 2 is positioned on the base plate 1 by fasteners 3 passing through the positioning hole 21.

[0029] The crystal lever head is placed in the positioning groove 11a, and then the positioning strip 2 is pressed against the side wall of the fixing part 11. To improve the positioning effect of the positioning strip 2, tape 5 is pasted on the side wall of the positioning strip 2. The positioning strip 2 is pressed tightly against the side wall of the fixing part 11 and covers the positioning opening 11a1. The tape 5 of the positioning strip 2 can adhere to the side wall of the crystal lever head located in the positioning groove 11a. Then the positioning strip 2 is connected to the base plate 1. Thus, the positioning strip 2 and the side wall of the positioning groove 11a are aligned with the two side walls of the crystal lever head. For positioning, since the upper surface and outer wall of the crystal lever head are irregular surfaces, the positioning effect of the crystal lever head is improved by pressing and bonding. In addition, for easy positioning, a waist-shaped positioning hole 21 is opened on the positioning strip, so that the positioning pressure strip 2 can move along the width direction of the fixing part 11. When the crystal lever head protrudes from the positioning groove 11a along the width direction of the fixing part 11, it can also be positioned by bonding and pressing. The positioning pressure strip 2 can also be fixed on the base plate 1, improving the positioning effect and stability.

[0030] The positioning strip 2 can also be attached to the fixing part 11 by tape 5.

[0031] like Figure 1-3 As shown, the sidewall of the fixing part 11 is planar, the sidewall of the positioning strip 2 is in contact with the sidewall of the fixing part 11, and the bottom plate 1 has a prepositioning part 12 at both ends that is strip-shaped along the width direction of the fixing part 11. A limiting step 22 is provided on the lower bottom wall at both ends of the positioning strip 2. The prepositioning part 12 is embedded in the limiting step 22. The limiting step 22 abuts against the prepositioning part 12 along the length direction of the positioning strip 2. A fixing hole 12a is provided on the prepositioning part 12. The positioning hole 21 is provided on the limiting step 22. The sidewall of the limiting step 22 is in contact with the fixing part 11 along the width direction of the fixing part 11.

[0032] like Figure 1 and Figure 2 As shown, the base plate 1 has strip-shaped limiting parts 13 on both sides. The limiting parts 13 are arranged parallel to the fixing parts 11. There are two fixing parts 11. The positioning pressure strip 2 can be arranged between the limiting parts 13 and the fixing parts 11. There is a clearance space 4 between the fixing parts 11 and the limiting parts 13 and between two adjacent fixing parts 11, which allows the positioning pressure strip 2 to slide along the width direction of the fixing parts 11.

[0033] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
