Description

Technical Field

[0001] This invention relates to an equipment assembly and adjustment device, specifically providing an installation device for small spaces that can install various types of E-type snap rings. Background Technology

[0002] When assembling equipment, certain shaft parts require the installation of E-type snap rings. Snap ring installation requires snap ring pliers. Currently, common designs use thick snap ring chucks to clamp the snap rings securely. These pliers require a large operating space. Furthermore, during installation, the operator must exert force to open the pliers and secure them to the shaft part. This installation method is laborious and can lead to uneven stress on the snap ring, easily causing it to fall off. Because E-type snap rings are small, they are difficult to detect once fallen. In addition, once the snap ring is installed on the shaft part, the tension makes it difficult to remove the pliers. Most importantly, currently available E-type snap ring pliers only correspond to one type of E-type snap ring. If multiple types of E-type snap rings need to be installed, multiple pliers must be purchased, resulting in wasted resources. Summary of the Invention

[0003] To solve the above problems, the present invention provides a device for use in small spaces that can install various types of E-type retaining rings.

[0004] This invention provides an E-type retaining ring mounting device, specifically comprising: a right ball-end screw, an upper clamp, a right clamp, a left clamp, a left ball-end screw, a fixed base plate, a longitudinal screw, a pin, a fork bolt, a transverse knob, and a spring. The fixed base plate has a first threaded hole, a second threaded hole, and a slide rail. The longitudinal screw is threadedly connected to the fixed base plate through the first threaded hole. The fork bolt's screw passes upward through the second threaded hole and is fixedly connected to the transverse knob. A spring is fitted onto the fork bolt's screw, with one end abutting against the fixed base plate and the other end abutting against the head of the fork bolt. The left and right clamps are specifically shaped as bent sheet structures. The right clamp connects to the left... The upper end of the side chuck is hinged to the head of the fork bolt via a pin. The ball heads of the right and left ball screws slide within the slide rails. The threaded sections of the right and left ball screws are connected to the middle threaded sections of the right and left chucks, respectively. The lower ends of the upper, right, and left chucks form arc-shaped retaining ring grooves that do not penetrate the thickness and are used to clamp the E-type retaining ring. When the horizontal knob is turned, the fork bolt moves up and down, thereby causing the right and left chucks to move synchronously in opposite directions or relative to each other, thus releasing and clamping the E-type retaining ring. The longitudinal screw is connected to the upper chuck via a screw. Rotating the longitudinal screw causes the upper chuck to press the retaining ring downwards.

[0005] Preferably, a rotating handle is installed on the head of the longitudinal screw.

[0006] Preferably, the arc-shaped retaining grooves of the left and right clamps are arc-shaped grooves that do not penetrate the thickness.

[0007] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0008] This device features a narrow clamp, enabling operation in confined spaces. A longitudinal screw is threaded to the fixed base plate via a first threaded hole, forming a longitudinal ejection mechanism and increasing the lever arm, allowing operators to install snap rings with ease and accuracy. Furthermore, a clamping mechanism is designed where the upper ends of the left and right clamps are hinged to the heads of fork-type bolts via pins, and the ball heads of the left and right ball-end screws slide within tracks. These, combined with the lower ends of the upper, left, and right clamps, form an arc-shaped snap ring groove that does not penetrate the thickness, accommodating the installation requirements of various snap ring types. The device is also easy to remove, improving work efficiency. Attached Figure Description

Detailed Implementation

[0017] In the following description, embodiments of the invention will be described with reference to the accompanying drawings. In the description below, the same modules are denoted by the same reference numerals. Where the same reference numerals are used, their names and functions are also the same. Therefore, their detailed description will not be repeated.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not constitute a limitation thereof.

[0019] like Figures 1-6 As shown, the E-type snap ring mounting device provided in this embodiment of the invention includes a right ball head screw 1, an upper clamp 2, a right clamp 3, a left clamp 4, a left ball head screw 5, a fixing base plate 6, a longitudinal screw 7, a pin 8, a fork bolt 9, a transverse knob 10, a spring 11, a first threaded hole 12, a second threaded hole 13, and a slide rail 14.

[0020] In this invention, the fixed base plate 6 is connected to the left chuck 4 and the right chuck 3 via the left ball-end screw 5 and the right ball-end screw 1. The left chuck 4 and the right chuck 3 are bent, sheet-like structures. The threaded sections of the right ball-end screw 1 and the left ball-end screw 5 are connected to the threaded holes in the middle sections of the right chuck 3 and the left chuck 4, respectively. The upper ends of the left chuck 4 and the right chuck 3 are hinged structures. They are connected to the fork bolt 9 via a pin 8. The fork bolt 9 is threadedly connected to the horizontal knob 10 via the second threaded hole 13 on the fixed base plate 6. A spring 11 is provided between the fork bolt 9 and the fixed base plate 6. The lower ends of the upper chuck 2, the left chuck 4, and the right chuck 3 are provided with arc-shaped retaining spring grooves that do not penetrate the thickness. An E-type retaining spring is inserted into this groove, thereby fixing the E-type retaining spring to the E-type retaining spring clamp. The longitudinal screw 7 is threadedly connected to the fixed base plate 6 via the first threaded hole 12.

[0021] The clamping function of this invention is achieved through a hinge structure. The upper ends of both the left clamp 4 and the right clamp 3 are connected to the fork bolt 9 via pins 8. Since the horizontal knob 10 is threadedly connected to the fork bolt 9, turning the horizontal knob 10 in different directions causes the fork bolt 9 to move up and down, thereby causing the left clamp 4 and the right clamp 3 to move synchronously towards or relative to each other, thus releasing and clamping the E-type retaining spring. The left clamp 4 and the right clamp 3 are connected to the fixed base plate 6 via the left ball-end screw 5 and the right ball-end screw 1. Figure 4 As shown, the fixed base plate 6 is provided with a slide rail 14, and the ball heads of the left ball end screw 5 and the right ball end screw 1 slide within the slide rail 14. Figure 5As shown, when the left chuck 4 and the right chuck 3 move towards or relative to each other, they cause the ball heads of the left ball screw 5 and the right ball screw 1 to slide in the slide rail 14 of the fixed base plate 6, ensuring both relative positional relationship and movement. A rotating handle is provided at the end of the longitudinal screw 7. After clamping the snap ring, shaking the rotating handle causes the longitudinal screw 7 to drive the upper chuck 2 downward to press the snap ring. The rotating handle design increases torque, making it easier for the operator. Furthermore, the snap ring is subjected to uniform force, with the force direction vertically downward, avoiding the snap ring dislodgement caused by uneven force distribution in traditional E-type snap ring pliers.

[0022] like Figure 3 As shown, the left chuck 4 and right chuck 3 have narrower sidewalls. These narrower sidewalls not only improve the chuck's elasticity but also allow for operation in confined spaces. The lower ends of the left chuck 4, right chuck 3, and upper chuck 2 all have arc-shaped grooves that do not penetrate the thickness, allowing for perfect contact with the E-type retaining spring. Clamping is achieved through a hinge structure. Figure 5 and Figure 6 As shown, the upper ends of the left collet 4 and the right collet 3 are hinged to the fork bolt 9 via pins 8. When the horizontal knob 10 is turned clockwise, the horizontal knob 10 is threadedly connected to the fork bolt 9, causing the fork bolt 9 to compress the spring 11 and move upward. The fork bolt 9, through the hinge structure, causes the left collet 4 and the right collet 3 to move synchronously in opposite directions, thus clamping the retaining ring. After clamping the retaining ring, the rotating handle on the longitudinal screw 7 is turned clockwise. The longitudinal screw 7 is threadedly connected to the fixed base plate 6, causing the longitudinal screw 7 to move downward. After the retaining ring is inserted into the annular groove of the shaft-like part, the horizontal knob 10 is turned counterclockwise, causing the fork bolt 9 to move downward. The fork bolt, through the hinge structure, causes the left collet 4 and the right collet 3 to move synchronously in opposite directions, thus separating them from the retaining ring surface, allowing the device to be removed.

[0023] like Figure 7 As shown, the distance between the right chuck 3 and the left chuck 4 is preferably between 20 mm and 35 mm, and the distance between the fixed base plate 6 and the bottom of the upper chuck 2 is preferably between 70 mm and 85 mm.

[0024] Although embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.

[0025] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
