Description

Technical Field

[0001] The utility model relates to the technical field of clamp spring installation, in particular to a clamp spring installation device with a limiting function. Background Art

[0002] Due to the particularity of the material and structure of the circlip, it is necessary to use circlip pliers or other special installation tools to remove or install the circlip stuck on the hole diameter or shaft groove.

[0003] Chinese patent CN202321615129.4 discloses a mounting device for a retaining ring. The utility model cooperates with a horizontal driving cylinder, a T-shaped guide rail sliding mounting seat, a fixed clamping seat, a semi-cylindrical clamping groove, a T-shaped guide rail and an arc-shaped clamping groove on a movable clamping seat to facilitate fast fixing of the workpiece under the pressure tube, and then the sleeve is sleeved on the outside of the workpiece through the workpiece insertion groove at its bottom. At this time, the retaining ring is sleeved in the annular recessed groove position of the sleeve, and then the retaining ring can be quickly pressed into the retaining ring mounting groove position of the workpiece by cooperating with the vertical driving cylinder and the pressure tube, so that the retaining ring is clamped in the retaining ring mounting groove position of the workpiece.

[0004] However, the above-mentioned mounting device of the retaining spring has many components, and needs to use multiple cylinders for clamping and installation, and lacks a buffer limit for the pressure tube, which may cause the pressure tube to be pressed down too much and cause damage to the workpiece or the mounting device.

[0005] Based on this, the utility model designs a retaining spring installation device with a limiting function to solve the above problem. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the utility model provides a retaining spring installation device with a limiting function.

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A retaining spring installation device with a limiting function comprises a housing, on which a limit-pressing assembly for pressing down the retaining spring and preventing the product from being crushed is installed; and a positioning assembly for positioning the product and the retaining spring for easy installation is installed on the housing;

[0009] The pressing and limiting assembly comprises a pressing assembly and a limiting assembly, both of which are connected to the shell, and the pressing assembly and the limiting assembly are connected.

[0010] Furthermore, the positioning assembly includes a lower mold, a guide jig, a retaining spring positioning block and a product positioning block; the lower mold is fixedly connected to the inner bottom of the shell, the guide jig is inserted into the upper end of the lower mold, the lower mold is fixedly connected to the inner bottom of the product positioning block, and the inner wall of the guide jig is fixedly connected to the retaining spring positioning block.

[0011] Furthermore, a guiding inclined surface is provided on the top of the guiding fixture to facilitate the sliding of the retaining spring.

[0012] Furthermore, the downward pressure assembly includes a cylinder, a connecting plate and a pressure block; the cylinder is fixedly installed on the top of the shell, the output end of the cylinder is fixedly connected to the connecting plate, the middle part of the lower side of the connecting plate is fixedly connected with a pressure block, and the connecting plate and the pressure block are both connected to the limit assembly.

[0013] Furthermore, the pressing block is located directly above the lower die.

[0014] Furthermore, the limit assembly includes a limit column, a guide cylinder, a buffer spring, a limit block and an avoidance groove; the lower ends of the limit columns are fixedly connected to the inner bottom of the shell, the outer side of the limit column is provided with a guide cylinder, the lower ends of the guide cylinder are fixedly connected to the inner bottom of the shell, the upper end of the guide cylinder is fixedly connected to the limit block, the outer wall of the limit column is provided with a buffer spring, the two ends of the buffer spring are respectively fixedly connected to the connecting plate and the shell, and the buffer spring is located between the guide cylinder and the limit column.

[0015] Furthermore, both left and right ends of the connecting plate are slidably connected to the limiting columns.

[0016] Furthermore, an avoidance groove is provided at the bottom of the pressing block.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1. When the retaining ring needs to be installed in the installation groove of the product, the positioning assembly is used to position the product and the retaining ring, and then the cylinder is started. The cylinder drives the connecting plate to move downward through the limiting guide of the limiting column. During the downward movement of the connecting plate, the buffer spring is squeezed for buffering. The connecting plate drives the pressing block to descend, and the pressing block presses the retaining ring downward so that the retaining ring enters the installation groove along the outer wall of the guide fixture to complete the installation. At the same time, when the pressing block is pressed down too much, the limiting block will block the connecting plate to stop the pressing block from moving down, thereby preventing the pressing block from being pressed down too much and damaging the product. The avoidance groove avoids the guide fixture and the retaining ring positioning block during the downward pressing process. The structure is simple and convenient, and the relative position of the product and the retaining ring can be ensured during press-fitting.

[0019] 2. When it is necessary to install the retaining ring in the installation groove of the product, first put the retaining ring on the guide fixture, align the notch of the retaining ring with the retaining ring positioning block for positioning, place the product on the lower die, and the lower die limits the product. By aligning the notch of the product with the product positioning block for positioning, and then plugging the lower die with the guide fixture, the positioning of the product and the retaining ring can be achieved, which is convenient for the subsequent installation of the retaining ring into the installation groove of the product.
