Description

Technical Field

[0001] This utility model relates to a tooling for applying sealant to the rear cover of an oil pump, belonging to the field of mechanical seal technology. Background Technology

[0002] During the assembly of the oil pump assembly, the sealing performance between the rear cover and the housing directly affects the reliability of equipment operation. In traditional processes, operators typically use a hand brush to manually apply sealant to the sealing surface of the rear cover to achieve uniform coverage. However, this method has the following technical drawbacks:

[0003] 1. Insufficient coating uniformity: During the brush coating process, the application pressure, coating speed and angle all rely on manual experience for control, which can easily lead to uneven thickness of the sealant layer or local missed coating, significantly increasing the risk of sealant failure.

[0004] 2. Pollution of the working environment: In an open operating environment, sealant is prone to splashing or remaining in uncoated areas, making it difficult to meet the cleanliness requirements of the back cover and housing assembly surfaces, requiring additional cleaning procedures.

[0005] 3. Low work efficiency: The coating cycle for a single product is long and the repetitive labor intensity is high, which does not meet the technical requirements of modern manufacturing for production efficiency and quality control.

[0006] To address the aforementioned technical bottlenecks, existing technologies have not yet provided a dedicated tooling that can balance coating accuracy, operational efficiency, and cleanliness, resulting in the common industry problems of low standardization and difficulty in quality control in the oil pump rear cover sealing process. Summary of the Invention

[0007] To address the problems existing in the background art, this utility model provides a tooling for applying sealant to the rear cover of an oil pump.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a tooling for applying sealant to the rear cover of an oil pump, comprising a base plate, a support plate, and a sizing pad; the upper end of the base plate is detachably and fixedly connected to the support plate, the support plate has an adhesive cavity inside, and the upper surface of the support plate has a plurality of adhesive outlet holes communicating with the adhesive cavity, and a sizing pad is placed above the adhesive outlet holes; the adhesive cavity and the base plate are sealed together.

[0009] Furthermore, the middle part of the support plate is fixedly connected to the lower end of the vertically arranged positioning pin.

[0010] Furthermore, a sliding plate and a compression spring are fitted on the outer side of the positioning pin from top to bottom. The lower end of the compression spring abuts against the support plate, and the upper end of the compression spring abuts against the sliding plate.

[0011] Furthermore, a pressure ring is installed on the upper surface of the adhesive pad, and the pressure ring is fixedly connected to the support plate by fixing nails.

[0012] Furthermore, a piston is inserted into the side wall of the support plate, and the inner end of the piston extends into the rubber cavity.

[0013] Furthermore, a guide pin is installed on the upper surface of the support plate.

[0014] Furthermore, a dust cover is provided at the upper end of the support plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model adopts a structure that combines a support plate with a glue cavity and a glue pad, and uses positioning pins to achieve standardized positioning. This allows the sealant to be released quantitatively through a pre-set glue outlet, solving the problems of uneven glue layer thickness and missed coating caused by manual coating, and significantly improving the coating accuracy of the sealing surface.

[0017] 2. This utility model uses the synergistic action of the sliding disc driven by the compression spring and the pressure ring to automatically complete the smoothing action of the adhesive layer during the assembly process. Combined with the dust cover design, it effectively suppresses adhesive splashing and ensures that the cleanliness of the coated area meets the requirements of precision assembly.

[0018] 3. This utility model integrates a piston-type glue supply system and a guide pin quick positioning mechanism, enabling standardized glue application to be completed in a single clamping operation, significantly shortening the production cycle of a single product, reducing labor intensity, and solving the problems of difficult quality control and low production efficiency.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0027] A tooling for applying sealant to the rear cover of an oil pump includes a base plate 1, a support plate 5, and an adhesive pad 12. The upper end of the base plate 1 is detachably fixed to the support plate 5 by corresponding screws. The support plate 5 has an adhesive cavity 2 arranged circumferentially inside it. The upper surface of the support plate 5 has a plurality of adhesive outlet holes arranged in an array and communicating with the adhesive cavity 2. The adhesive pad 12 is placed above the adhesive outlet holes. The adhesive cavity 2 and the base plate 1 are sealed together by an adhesive ring.

[0028] Furthermore, the middle part of the support plate 5 is threadedly fixed to the lower end of the vertically arranged positioning pin 7, and the upper end of the positioning pin 7 is inserted into the middle of the product for coarse positioning of the product.

[0029] Furthermore, a sliding disc 8 and a compression spring 6 are fitted on the outer side of the positioning pin 7 from top to bottom. The lower end of the compression spring 6 abuts against the support disc 5, and the upper end of the compression spring 6 abuts against the sliding disc 8.

[0030] The sliding plate 8 supports the product to slide up and down. After pressing the product down, the product contacts the adhesive pad 12. The sealant adsorbed on the adhesive pad 12 is evenly applied to the product. The compression spring 6 realizes the product's reset after the adhesive is applied, which facilitates the disassembly of the product.

[0031] Furthermore, a pressure ring 11 is installed on the upper surface of the adhesive pad 12. The pressure ring 11 is fixedly connected to the support plate 5 by a fixing nail 13. The pressure ring 11 restricts the position of the adhesive pad 12 to prevent the adhesive pad 12 from being taken down with the product when it is disassembled.

[0032] Furthermore, a piston 10 is inserted into the side wall of the support plate 5, and the inner end of the piston 10 extends into the glue cavity 2. The height of the glue liquid level is adjusted by the insertion depth of the piston 10. A rubber ring is provided between the piston 10 and the support plate 5 to prevent glue leakage.

[0033] Furthermore, a guide pin 15 is installed on the upper surface of the support plate 5 to precisely position the product.

[0034] Furthermore, a dust cover 14 is provided at the upper end of the support plate 5, and the dust cover 14 is detachably connected to the support plate 15.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of the equivalents of the claims be included within this invention.
