Description

Technical Field

[0001] The present invention relates to the technical field of connection tooling, in particular to a piston-type electroplating quick connection tooling. Background Art

[0002] The piston rod is a critical component in hydraulic jacks, and its quality plays a crucial role in the jack's performance. To prevent rust during use and improve its wear resistance, weather resistance, and hardness, the piston rod requires electroplating during production. However, existing piston rod electroplating tooling presents numerous issues, limiting the efficiency and safety of the electroplating process.

[0003] The traditional piston rod electroplating connection tooling (see patent No. 202022463302.6, which discloses a piston rod electroplating connection tooling) usually adopts a sleeve structure with four holes. When connecting, the piston end of the piston rod needs to be inserted into the tooling, and then a nail is inserted into the hole, and further inserted into the sealing groove of the piston rod. Finally, the nail is hammered with a hammer to make it firmly stuck in the hole and the groove of the piston rod. This connection method not only requires the use of a large number of nails, which increases additional cost expenditure, but also the operation process is cumbersome and requires multiple actions to complete the connection. In addition, this operation method also has a high safety risk. Since a hammer is needed to hit the nail, it is easy to make a mistake during the operation, which may hit the operator's hand and cause personal injury. This not only affects work efficiency, but may also cause safety accidents. In addition, the traditional connection tooling also has shortcomings in sealing performance. Due to the limitations of the structural design, liquid can easily penetrate from the connection, causing the tooling to fail to work properly during the electroplating process, affecting the quality and efficiency of the electroplating. Summary of the Invention

[0004] In response to the above-mentioned defects and problems, the present invention provides a piston-type electroplating quick connection tool, which solves the problems of traditional tooling such as cumbersome operation, the need to hammer nails multiple times resulting in low efficiency, personal safety hazards, and poor sealing affecting electroplating quality. It realizes the rapid connection and release of the piston rod, and improves work efficiency and safety.

[0005] The solution adopted by the present invention to solve the technical problem is: a piston-type electroplating quick connection tool, including a sleeve and a piston rod, and also including:

[0006] The tooling housing is fixedly mounted on the outer wall of the sleeve. The interior of the tooling housing is divided into two cavities, a large cavity and a hollow cavity. The large cavity and the hollow cavity are designed at 90 degrees and are interconnected.

[0007] A key is slidably disposed in the large cavity of the tool housing, with a square groove formed between the tail end of the key and the large cavity;

[0008] The spring is mounted on the thin rod at the front end of the key, and the two ends of the spring are respectively in contact with the switch cap at the front end of the key and the sealing cover at the front end of the tooling housing;

[0009] The lock rod is arranged in a movable groove on the square rod at the tail end of the key, the front end of the lock rod is connected to the key through a pin, and the tail end of the lock rod is elastically connected to the spring cap through a lock column;

[0010] A lock groove is provided in the cavity, the lock groove being composed of a lock groove a and a lock groove b. The lock groove a is a one-way groove inclined upward, and the lock groove b is provided horizontally. The lock groove a and the lock groove b form a large V-shaped structure in the cavity, and the ends of the lock groove a and the lock groove b are connected by a step groove.

[0011] A sealing structure is provided on the front side of the tool housing and the key to seal the tool housing and the key;

[0012] The locking rod cooperates with the locking groove to realize the locking function. The inclined surface design of the lock groove a enables the lock column on the locking rod to move in a directional manner along the inclined surface. When the lock column reaches the step groove of the turning point of the lock groove, the spring cap is compressed into the lock column, and the lock column falls under the step groove. The spring cap extends out of the lock column under the thrust of the top spring and presses tightly against the step groove of the lock groove, locking the locking rod in a specific position, thereby driving the key to move to the locked position, thereby locking the piston rod.

[0013] Furthermore, the tail end of the key is a square rod with a keyway, the front end of the key is a round rod with a thread b, and the front end of the key is connected to the switch cap by means of a thread.

[0014] Furthermore, a spring is mounted on the thin rod at the front end of the key, and both ends of the spring respectively abut against the switch cap and the sealing cover at the front end of the key. The key slides into the square groove under force, and the reset function of the spring pushes the key forward and returns to its original position.

[0015] Furthermore, a lock column is provided at the tail end of the lock rod perpendicular to the rod body, a lock plug is fixed to the bottom of the lock column, the spring cap is connected to the lock column through a top spring, and the two ends of the top spring are respectively connected to the spring cap and the lock plug.

[0016] Furthermore, the groove surface of the lock groove a is in an inclined state, the groove surface of the lock groove b is a plane, the roots of the lock groove a and the lock groove b are connected, and the two ends of the lock groove a and the lock groove b are connected by a step groove with a small V-shaped structure.

[0017] Furthermore, the sealing structure includes a sealing cover, an annular gasket, an annular sealing ring and an umbrella-shaped soft connection. The sealing cover is arranged at the front end of the tooling shell, and an annular cavity is provided therein. The annular gasket is clamped in the annular cavity, and the annular sealing ring is installed in the annular cavity. The sealing cover cooperates with the special seal through the annular gasket to seal the large cavity and square groove at the tail end of the tooling shell.

[0018] Furthermore, the umbrella-shaped flexible connection flexibly connects the switch cap to the front end of the tooling housing, which can ensure the flexible movement of the switch cap and prevent liquid from leaking from the connection.

[0019] Furthermore, the tooling shell is integrally cast using engineering plastic.

[0020] The beneficial effects of the present invention are as follows: the present invention realizes the rapid connection and release of the piston rod through the unique design of the lock rod and the lock groove, and the elastic action of the spring and the spring cap. The operator only needs to press the switch cap to complete the locking or loosening of the piston rod, which greatly simplifies the operation steps and improves work efficiency. Compared with the traditional method of hammering nails multiple times, it saves a lot of time and labor costs, and avoids the risk of personal injury caused by hammering errors, and significantly improves the safety of the operation process; the design of multiple sealing structures, including sealing covers, annular clamping pads, annular sealing rings and umbrella-shaped soft connections, ensures the sealing performance of the tooling during the electroplating process, prevents liquid infiltration, and further ensures the safety of the operator and the normal operation of the equipment; the tooling shell is made of engineering plastic and cast in one piece, which has high strength and stability, while reducing the weight of the tooling and facilitating operation and transportation. The internal lock groove, lock rod, keyway and other structures are reasonably designed and cooperate closely with each other, which can stably clamp the piston rod, ensuring that it will not loosen during the electroplating process, thereby improving the electroplating quality.

DETAILED DESCRIPTION

[0033] The present invention will be further described below with reference to the accompanying drawings and examples.

[0034] See also Figure 1-11 , the present invention provides a technical solution for a piston-type electroplating quick-connect tooling:

[0035] Example 1:

[0036] according to Figure 1 and Figure 2As shown, a piston-type electroplating quick-connect tool mainly includes a sleeve 27 and a tool housing 14. The tool housing 14 is fixedly set on the outer wall of the sleeve 27. A locking structure is set in the tool housing 14. The locking structure cooperates with the sleeve 27 to realize the quick connection of the piston rod 21. The tool housing 14 is cast in one piece using engineering plastic. The interior of the tool housing 14 is divided into two cavities. The two cavities are designed at 90 degrees, namely a large cavity and a cavity 17. The large cavity and the cavity 17 are connected. A key 23 is slidably sleeved in the cavity of the tool housing 14, and a square groove 20 is formed between the tail end of the key 23 and the large cavity of the cavity. A sealing cover 25 is provided at the front end of the tool housing 14. An annular cavity 25-2 and an annular clamping gasket 25-1 stuck in the annular cavity 25-2 are provided in the sealing cover 25. The large cavity and the square groove 20 at the tail end of the tool housing 14 can be sealed by the sealing cover 25. The front end of the key 23 The thin rod at the end is inserted into the annular cavity, and the thick rod at the rear end is inserted into the large cavity. A spring 28 is installed on the thin rod at the front end of the key 23. The two ends of the spring 28 are respectively in contact with the switch cap 1 and the sealing cover 25 at the front end of the key 23. The key 23 can slide into the square groove 20 under force, and the reset function of the spring 28 pushes the key 23 forward and back to its original position. The key 23 in the tooling housing 14 realizes a piston-like reciprocating motion through the elastic action of the spring 28: when the switch cap 1 is pressed, the spring 28 is compressed, and the key 23 slides into the square groove 20; after the switch cap 1 is released, the elastic potential energy of the spring 28 is converted into kinetic energy, pushing the key 23 forward and back to its original position.

[0037] The thick rod at the tail end of the key 23 is a square rod with a key slot 22 on it, and the thin rod at the front end is a round rod with a thread b26 on the front end. A switch cap 1 is installed at the front end of the key 23, as shown in FIG. Figure 4 As shown, the inner wall of the switch cap 1 is provided with a thread a4, and the outer wall of the front end of the key 23 is provided with a thread b26. Through the cooperation of the thread a4 and the thread b26, the switch cap 1 is installed and connected to the front end of the key 23 in the direction of the thread, and the switch cap 1 is installed and connected to the front end of the sealing cover 25 through the umbrella-shaped soft connection 3. An annular sealing ring 2 is provided at the front end edge of the annular cavity of the sealing cover 25 at the front end of the tooling housing 14. The two ends of the umbrella-shaped soft connection 3 are respectively fixed on the switch cap 1 and the annular sealing ring 2, so that the switch cap 1 is flexibly connected to the front end of the tooling housing 14 in an umbrella-shaped structure.

[0038] The annular clamping gasket 25-1, annular sealing ring 2, and umbrella-shaped flexible connector 3 within the sealing cover 25 work together to form a multi-sealing structure. The sealing cover 25, through the annular clamping gasket 25-1, cooperates with the dedicated seal 6 to seal the large cavity at the rear end of the tool housing 14 and the square groove 20. The annular sealing ring 2 is installed in the annular cavity at the front end of the tool housing 14, further enhancing the sealing performance. The umbrella-shaped flexible connector 3 flexibly connects the switch cap 1 to the front end of the tool housing 14, ensuring flexible movement of the switch cap 1 while preventing liquid leakage from the connection, ensuring that the tooling will not be affected by liquid infiltration during the electroplating process.

[0039] The cavity 17 in the tooling housing 14 is a trapezoidal structure and is designed at 90 degrees to the large cavity at the tail end, and the cavity 17 is connected to the square groove 20, as shown in FIG. Figure 5 As shown, a lock groove is provided in the cavity 17, and the lock groove is composed of a lock groove a7 and a lock groove b19. The lock groove a7 is a one-way groove inclined upward, and the starting point of each turning point of the lock groove a7 is low and gradually raised to the end point, so that the middle groove surface of the lock groove a7 is in an inclined state, and the lock groove b19 is designed as an object with the lock groove a. The lock groove b19 is horizontally arranged, and the inner groove thereof is a plane. The lock groove a7 and the lock groove b19 form a large V-shaped structure in the cavity 17, and the roots of the lock groove a7 and the lock groove b19 are connected. The two ends of the lock groove a7 and the lock groove b19 are connected by a step groove 8 in a small V-shaped structure, that is, the tail of the lock groove is designed with a step groove 8, and the turning position of each groove is a step, so that the lock rod can press in the lock groove. Figure 3 Move along the indicated trajectory.

[0040] like Figure 9 and Figure 10 As shown, a movable groove 24 is provided on the square rod at the tail end of the key 23, a lock rod 5 is installed in the movable groove 24, a pin 12 is installed on the front side of the movable groove 24, a connecting hole 13 is provided at the front end of the lock rod 5, the lock rod 5 is connected to the pin 12 through the connecting block at the front end, so that the lock rod 5 can rotate around the pin 12 in the movable groove 24; the tail end of the lock rod 5 is elastically connected to the spring cap 10, as shown in FIG. Figure 6 and Figure 7As shown, the tail end of the lock rod 5 is provided with a lock column 9 perpendicular to the rod body. A lock plug 16 is fixed to the bottom of the lock column 9. A spring cap 10 is slidably connected to the front end of the lock column 9. The spring cap 10 is connected to the lock column 9 by a top spring 15. The two ends of the top spring 15 are respectively connected to the spring cap 10 and the lock plug 16, so that the spring cap 10 is elastically connected to the tail end of the lock rod 5. The lock column 9 on the lock rod 5 cooperates with the lock groove to achieve the locking function. The inclined surface design of the lock groove a7 enables the lock column 9 to move in a directional manner along the inclined surface. When the lock column 9 reaches the turning point step of the lock groove, the spring cap 10 is compressed into the lock column 9, and the lock column 9 falls under the step. The spring cap 10 extends out of the lock column 9 under the thrust of the top spring 15 and is tightly fixed at the step of the lock groove, thereby locking the lock rod 5 in a specific position, thereby driving the key 23 to move to the locked position, thereby locking the piston rod 21.

[0041] When in use, the present invention provides a piston-type electroplating quick connection tool. When in use, the switch cap 1 is pressed, and the spring 28 is compressed inwardly. At this time, the lock column 9 on the lock rod 5 moves along the inclined surface of the lock groove a7, and the elastic cap 10 on the lock column 9 is forced to be compressed into the lock column 9. When the tail end of the lock rod 5 passes the turning point step, the lock column 9 falls under the step, and the elastic cap 10 extends out of the lock column 9 under the thrust of the top spring 15, and presses tightly against the step groove of the lock groove. Since the step groove is at the turning point position and is connected to the groove wall of the turning point, the lock column 9 can only move along the set running trajectory during operation and is stuck in the groove of the step groove. When the switch cap 1 is pressed again, the elastic cap 10 is compressed and retracted into the lock column 9, and the lock column 9 is compressed and returns to its original position.

[0042] When the key 23 is in the open position, the key slot 22 on the key 23 corresponds to the opening position of the piston cavity of the piston rod 21. The piston rod 21 can be inserted into the sleeve along the piston cavity and the vacancy of the key slot 22. Then, the switch cap 1 is pressed to drive the key 23 to move inward. When the lock column 9 is stuck in the stuck position, the key slot 22 of the key 23 moves inward. At this time, the protruding part of the key 23 just sticks to the sealing groove of the piston, and the piston rod 21 is stuck. The lifting and electroplating operation of the piston rod 21 can then be carried out. When the lock column 9 is stuck, the switch cap 1 is located in the annular cavity, and the cap top is flush with the end face of the annular cavity to avoid automatic popping out due to collision.

[0043] Example 2:

[0044] On the basis of the first embodiment, a plurality of circular holes 18 and threaded holes 11 are further provided on the tool housing 14. When assembling the device, the connecting hole 13 end of the lock rod 5 is first placed in the movable groove 24, and the pin shaft 12 is fixed to the connecting hole 13 through the hole on the key 23. At this time, the pin shaft 12 and the hole on the key 23 are locked by interference fit. The connecting hole 13 and the pin shaft 12 are accompanied by a certain frame amount to facilitate left and right swinging. Then, the square rod of the key 23 is inserted into the cavity of the tool housing 14, and inserted into the square groove 20 along the annular cavity. Then, the lock rod 5 is lifted, and the lock plug 16 end on the lock rod 5 is placed in the lock groove a7, and the special Place the seal 6 into the sealing groove of the exposed part of the square groove 20 in the cavity of the tool housing 14, then align the annular gasket 25-1 of the sealing cover 25 with the special seal 6 and put it in. Screw the bolt through the round hole 18 into the threaded hole 11, then insert the spring 28 into the round rod of the key 23, tighten the switch cap 1 to the thread b26, and then install the annular sealing ring 2 into the annular groove of the tool housing 14, and then install the umbrella-shaped soft connection 3 in the annular groove at the front end of the tool housing 14 to form a completely sealed state. The assembly of the tool can be completed and it can be used in the electroplating quick connection work of the piston rod 21.
