Description

Technical Field

[0001] The utility model belongs to the technical field of metal rubber vulcanization, and in particular relates to a stably clamped glue spraying device. Background Art

[0002] Mandrel vulcanized parts are widely used in various shock absorber ends or connecting rod / swing arm ends. Through the elastic deformation of the annular rubber body between the two rubber metal tubes, flexible connections between different parts are achieved. At present, the mandrel vulcanized parts produced need to be sprayed with adhesive. Most of the product mandrels are special-shaped parts. Ordinary tooling cannot meet the requirements of spraying. In order to perfectly ensure that only the bonding area is sprayed, so as to reduce the work intensity of the subsequent process and achieve the effect of vibration reduction, the existing spraying tooling has a fixed tolerance, which will cause the out-of-tolerance parts to not fit into the tooling. If the tolerance is too small, the tooling and workpiece will shake significantly when rotating, and the spraying area will fluctuate greatly, which cannot meet the spraying requirements. It is necessary to develop a new type of spraying tooling to solve the above problems.

[0003] After searching, application number CN202320883893.3 discloses a glue spraying tool to prevent glue overflow, including an upper shell and a lower shell installed on both sides of the product to be sprayed; the product to be sprayed includes an end to be sprayed and a clamping end arranged on both sides of the end to be sprayed; the upper and lower shells include a flap-type clamping body, the flap-type clamping body includes a accommodating cavity and a connecting end and a rotating end disposed at both ends of the accommodating cavity; the connecting end is connected by a rotating shaft, so that the rotating end of the flap-type clamping body changes the angle, so as to achieve the deep accommodating cavity and fix the end of the product to be sprayed; any end of the upper and lower shells is installed on the inner wall of the rotating seat, and the rotation of the rotating seat drives the product to be sprayed to rotate synchronously to achieve the effect of spraying. This solution is used to solve the glue overflow problem of such products, greatly improve the glue spraying quality and vulcanization efficiency, increase the allowable rotation speed of the product during glue spraying, and is more conducive to the uniformity of glue spraying, improve the efficiency and quality of glue spraying, and has a huge market promotion prospect.

DETAILED DESCRIPTION

[0026] The utility model is further described below in conjunction with the accompanying drawings. The accompanying drawings are only used for exemplary descriptions, and are only schematic diagrams, not actual pictures, and cannot be understood as limiting the present patent; in order to better illustrate the embodiments of the utility model, some parts of the accompanying drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the accompanying drawings may be omitted. Example 1

[0027] like Figure 1-Figure 5 As shown, the stably clamped glue spraying device of this embodiment includes a shell 1 installed in a pair; both ends of the product to be sprayed extend into the shell 1; the shell 1 is a semi-cavity structure, and the openings of the two semi-cavity structures are coaxially arranged opposite to each other, and the semi-cavity structure includes a cavity 11 for accommodating the product and an adjustment device radially distributed on both sides of the cavity 11, and the adjustment device is embedded in the side wall of the shell 1, and the adjustment device includes an adjustment end 200 and an abutment end 300, and the adjustment end 200 is connected to the abutment end 300 by an elastic structure 400, and the abutment end 300 contacts and cooperates with the product to be sprayed; the space size of the semi-cavity structure is changed by adjusting the position of the adjustment device to clamp and release the product to be sprayed.

[0028] The stable clamping glue spraying device is designed with a pair of shells (upper shell and lower shell) installed in pairs according to the structure of the product to be sprayed. The upper shell and the lower shell clamp the two ends of the product to be sprayed, and an adjustment device is set. By adjusting the position of the adjustment device, the space size of the semi-cavity structure is changed to clamp and loosen the product to be sprayed. It can be applied to the effective clamping of products of different sizes, with good fixing effect, improved spraying efficiency, guaranteed the spraying quality of the product, and provided guarantee for subsequent processes.

[0029] In order to smoothly extend the product to be sprayed into the interior of the housing to be fixed and clamped, a guide structure 8 is provided at the open end near the housing 1, including a mounting end 81 and a mating end 82. The mounting end 81 extends from the edge of the housing 1 to the inside and is fixedly connected to the housing 1; the mating end 82 is loosely matched with the abutment end 300. The guide structure 8 in this embodiment is plate-shaped and is vertically arranged at the edge of the housing 1 connected thereto. The abutment end 300 is connected to the elastic structure 400 as a whole through the support pin 4; the length of the support pin 4 is greater than the natural length of the elastic structure 400.

[0030] The abutting end 300 is a positioning clamping piece 5 for mounting one end of the support pin 4; the positioning clamping piece 5 does not interfere with the guide structure 8. When the elastic structure 400 is at its natural length, the relative distance of the positioning clamping piece 5 is less than or equal to the maximum cross-sectional dimension of the clamping end of the product to be sprayed.

[0031] The guide structure 8 is centrally symmetrically arranged. Figure 3 There is one on each side, and the guide structure 8 is a plate-like structure extending from the open end to the inside of the cavity. In order to avoid interference during placement and improve the efficiency of the device, the spacing between the relatively arranged guide structures 8 is greater than the cross-sectional width of the product to be sprayed.

[0032] The adjusting device in this embodiment is embedded in the side wall of the shell 1, and in this embodiment, it is welded on the shell 1. The adjusting device includes a spring cover 2, and the inner wall of the spring cover 2 is provided with a cavity 21. The cavity 21 includes a latch accommodating cavity 211 and a spring accommodating cavity 212, and the cross section formed is a "convex" structure; the latch accommodating cavity 211 is close to the outside of the spring cover 2, and the spring accommodating cavity 212 accommodates one end of the elastic structure 400. The spring cover 2 is clearance-matched with the positioning clamping sheet 5. The structure of the cavity 21 plays a role in positioning and blocking the elastic structure 400. When placing the product to be sprayed, the elastic structure 400 will be squeezed to the left and right sides of the device as the product size is different. Since the elastic force of the spring structure 400 acts toward the center of the device, the product to be sprayed is stably clamped in the device.

[0033] In order to facilitate the operation of the gluing process, a shaft body 6 that can drive the lower shell to rotate can be arranged at the bottom of the lower shell, and a positioning sleeve 7 for protection is arranged outside the shaft body 6.

The adjusting device is partially embedded in the housing, and the volume of the cavity one can be adjusted by the distance of the adjusting device extending into the housing. The space clamped by the entire device can be adjusted according to the product size, and the needs of products of different sizes can be met, and the versatility is enhanced. The above is only an embodiment of the utility model, and the utility model is not limited to the field involved in this implementation case.
