Description

Technical Field

[0001] The utility model relates to a device for machining a plunger seat. More specifically, it relates to a device for machining a plunger seat that is mechanized, improves machining efficiency, and ensures machining accuracy. Background Art

[0002] The plunger seat is a supporting and positioning component of the plunger, which ensures that the plunger can maintain a stable trajectory and direction during reciprocating motion.

[0003] Currently, the devices for machining plunger seats on the market are generally produced manually, with the characteristics of low machining efficiency, low precision, low mechanization degree, and high labor cost. For manufacturers, the manufacturing cost is high, which is not conducive to sales; for users, the precision during use is low and the practicability is poor. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a device for machining a plunger seat that is mechanized, improves machining efficiency, and ensures machining accuracy.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A device for machining a plunger seat, including a workbench, a bottom plate arranged on the workbench, a disc-type brake tailstock and a cam turntable oppositely arranged on the bottom plate, and a clamping plate arranged between the disc-type brake tailstock and the cam turntable. A plurality of machining devices are arranged on the clamping plate. The machining device includes a machining part arranged on the top of the clamping plate, a driving part arranged on the bottom of the clamping plate, and a transmission device for connecting the machining part and the driving part. The driving part is an oil cylinder, and the power generated by the oil cylinder makes the transmission device reciprocate up and down, so that the transmission device drives the machining part to perform machining.

[0006] By adopting the above technical solution, the advantages of the four-axis cam turntable include a large indexing range, simple structure, strong load-bearing capacity, low manufacturing cost, and high indexing accuracy. Through mechanized production, the quality of the products produced during machining is improved, the machining accuracy is ensured, and the machining device is divided into a driving part, a transmission structure, and a machining part, making the structure simple and the practicability strong.

[0007] The utility model is further arranged as follows: The machining part is a tooling fixture. A plunger seat is placed on the top of the tooling fixture. Limiting parts for fixing the plunger seat are oppositely arranged on the front and rear sides of the tooling fixture, and the limiting parts are fixedly connected with the clamping plate. L-shaped pressing plates are oppositely arranged on the left and right sides of the tooling fixture. When the machining part starts to work, the L-shaped pressing plates reciprocate up and down, continuously pressing the plunger seat downward against the tooling fixture, so as to machine the plunger seat.

[0008] By adopting the above technical solution, a plunger seat arranged at the top of the workpiece clamped by the tooling and a positioning portion arranged between the workpiece clamped by the tooling and the plunger seat are provided. A limiting post is arranged at the bottom end of the plunger seat, and the limiting post is used to fix the position of the positioning portion, so that during the reprocessing, the plunger seat is fixedly placed on the tooling fixture through the limiting portion, thereby ensuring the processing quality.

[0009] The present utility model is further arranged as follows: the transmission device includes a double-rod structure arranged at the bottom end of the oil cylinder and a rod sleeved outside the double-rod structure and the L-shaped pressing plate. The double-rod structure is fixedly connected to the oil cylinder, and both the double-rod structure and the L-shaped pressing plate are fixedly connected to the rod. A notch is arranged on the clamping plate, so that the L-shaped pressing plate passes through the clamping plate.

[0010] By adopting the above technical solution, when the oil cylinder starts to work, the oil cylinder presses down the double-rod structure, thereby driving the rod to press down, so that the L-shaped pressing plate presses down; conversely, the L-shaped pressing plate returns upward, making the transmission device simple in structure, high in transmission efficiency and strong in practicability.

[0011] The present utility model is further arranged as follows: clamping members are further arranged on the clamping plate and are arranged on both sides of the L-shaped pressing plate. The clamping members are fixedly connected to the clamping plate and have a gap with the L-shaped pressing plate. The top end of the L-shaped pressing plate abuts against the circumferential side of the plunger seat. An obliquely upward through hole is arranged in the clamping member, and a positioning pin is arranged in the through hole. The clamping member and the L-shaped pressing plate are slidably connected through the positioning pin.

[0012] By adopting the above technical solution, when the L-shaped pressing plate moves downward under force, the L-shaped pressing plate presses down the plunger seat; conversely, when the L-shaped pressing plate moves upward, the L-shaped pressing plate is separated from the plunger seat, so that the plunger seat can be removed from the tooling fixture. Using the positioning pin and the through hole, the structure is simple, the installation and disassembly are convenient, and it is convenient for production.

[0013] The present utility model is further arranged as follows: a threaded hole is arranged in the oil cylinder, and the oil cylinder is threadedly connected to the double-rod structure.

[0014] By adopting the above technical solution, the double-rod structure provides higher stability and load-bearing capacity due to its strong stability, load-bearing capacity, compressive strength, durability, adaptability to multi-directional operation and optimized dynamic performance, ensuring the stability and safety of the structure.

The plunger seat 8 is arranged at the top of the workpiece clamped by the tooling, and a positioning part is arranged between the workpiece clamped by the tooling and the plunger seat 8. A limiting column is arranged at the bottom end of the plunger seat 8, and the limiting column is used to fix the position of the positioning part, so that during the processing, the plunger seat 8 is fixedly placed on the tooling fixture 7 through the limiting parts 9, thereby ensuring the processing quality.
