Description
Technical Field
The utility model relates to a clutch master cylinder.
Background
The clutch master cylinder is various in style, for example, a pump body of the clutch master cylinder is formed by two plastic shells in a rotating welding mode, a piston provided with a return spring is arranged in the pump body, the piston is connected with a push rod, the connecting parts of the two plastic shells are cylindrical, and the shells are sleeved with each other and are in interference matching. The rotary welding is easy to cause the welding material to be sputtered out in the process of high-speed rotation, and burrs and pimples formed after cooling need additional treatment; in addition, in the process of high-speed rotation, the sputtered welding material flows into the main leather ring to affect the sealing effect of the main leather ring, and even cause product rejection. Secondly, the stability of the spin welding is not high, the welding materials are too much or the plastics are not uniformly fused, so that the product is easy to leak or burst under high pressure, the rejection rate of the product is very high, the production cost of the product is increased, and the market competitiveness of the product is reduced.
SUMMERY OF THE UTILITY MODEL
In view of the technical problem that exists among the background art, the utility model aims at providing a novel welding mode's clutch master cylinder.
In order to solve the technical problem, the utility model discloses a following technical scheme: the utility model provides a novel welding mode's clutch master cylinder, including the pump body, the pump body is including first casing and second casing, its characterized in that: the port of first casing matches and cup joints in the interface of second casing, and port and connector clearance fit set up the laser welding circle between port and the connector, and the port has round platform shape outer wall, and the connector has round platform shape hole, still is equipped with the sealing washer in the junction between first casing and second casing, and the sealing washer is located the inboard of laser welding circle.
The connecting port is a step port, the end part of the port is provided with an outer step small opening, and the step port and the outer step small opening are combined to form a sealing ring mounting position.
The pump body is internally provided with a piston, the front end of the piston is connected with a return spring, the front end of the piston is provided with a first inner hole with a conical surface, and the return spring is connected to the bottom of the first inner hole.
The rear end of the piston is connected with a push rod, a connecting hook is arranged on the push rod, a second inner hole with a barb groove is formed in the rear end of the piston, and the connecting hook is matched with the barb groove.
This clutch master cylinder adopts novel welding mode to first casing and second casing laser welding, forms the laser welding circle between first casing and second casing and carries out interconnect, can not take place to run the material and can not form the burr, and welding stability is better, and is comparatively firm, and the sealing washer further ensures the leakproofness of the pump body in the junction, reduces the possibility of leaking, reduces the product disability rate.
Drawings
The following describes details and operational principles of embodiments and examples of the present invention with reference to the drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural diagram of a piston according to an embodiment of the present invention.
Detailed Description
Referring to the drawings, in the embodiment, the clutch master cylinder adopting the novel welding mode comprises a pump body which comprises a first shell 1 and a second shell 2, a port of the first shell 1 is matched and sleeved in a connecting port of the second shell 2, the first shell 1 and the second shell 2 are made of plastic materials, a piston 4 is arranged in the pump body, a return spring 5 is arranged at the front end of the piston 4, a push rod 7 is connected to the rear end of the piston 4, a main leather collar, a leather collar seat and the like are additionally arranged, and the clutch master cylinder is the prior art and is not repeated.
The utility model discloses in first casing 1 adopt the new mode to be connected-laser welding when connecting into the pump body with second casing 2, the port of first casing 1 and the connector clearance fit of second casing 2 set up laser welding circle A between port and the connector, produce high temperature through laser welding's mode in the junction and make first casing 1 and second casing 2 junction fuse each other and be connected, its stability is high, avoids splashing and leads to running the problem of material and burr. The transparent powder may be mixed in the plastic material of the second housing 2, and it is a prior art to mix the transparent powder in the plastic material. The port has round platform shape outer wall, and the connector has round platform shape hole for the welded effective area (length) is bigger under the coaxial axial distance during laser welding, connects more firmly, and the risk that the splice leaked is lower. Still be equipped with sealing washer 3 (like O type sealing washer) at the junction between first casing 1 and second casing 2, sealing washer 3 is located the inboard of laser welding circle A, and sealing washer 3 further ensures the leakproofness of the pump body in the junction, reduces the possibility of leaking, reduces the product disability rate.
The connecting port is a step port, the end part of the port is provided with an outer step small opening, and the step port and the outer step small opening are combined to form a sealing ring mounting position. Can press from both sides sealing washer 3 between step mouth and outer step osculum, be located sealing washer installation position department, convenient assembling, processing is convenient.
A piston 4 is arranged in the pump body, the front end of the piston 4 is connected with a return spring 5, a first inner hole 6 with a conical surface is formed in the front end of the piston, and the return spring 5 is connected to the bottom of the first inner hole 6. The piston adopts the first inner hole with the conical surface to be connected and matched with the return spring, the friction between the return spring and the side wall of the first inner hole during the work can be reduced, the piston is prevented from being damaged by the friction, and meanwhile, the influence of slag scraps generated by the friction on the sealing performance of leather rings (including a main leather ring and an auxiliary leather ring) is avoided,
the rear end of the piston 4 is connected with a push rod 7, and a second inner hole which is not provided with a barb groove is connected with the rear end of the piston 4 through the push rod 7 through a locking ring 10, so that the problems of falling off and high cost are easy to occur. As the improvement, can set up the coupling hook (can set up the round) on push rod 7, set up barb groove 9 in the second hole 8 of the rear end of piston 4, the coupling hook matches with barb groove, and barb groove corresponds can set up the round, directly fills in the second hole with the push rod during the assembly, and tight fit and coupling hook and barb groove are each other to be connected and are avoided breaking away from, and are more firm.
