Description

Technical Field

[0001] This utility model relates to the field of automotive piston processing technology, and in particular to a turning processing equipment for the end face of an automotive piston. Background Technology

[0002] The piston is a reciprocating component in the cylinder block of an automobile engine. The basic structure of a piston can be divided into the crown, head, and skirt. The piston crown is the main part of the combustion chamber, and its shape depends on the chosen combustion chamber configuration. Existing pistons are generally machined by turning.

[0003] A search revealed Chinese patent application number 201720104014.7, which discloses a simple piston turning device. This device includes a fixture, a fixture rotating part, an ejector pin, an ejector pin drive part, and a cutting tool. A piston can be fitted onto the fixture. The fixture rotating part is fixedly connected to the fixture and drives the fixture and piston to rotate around the piston's axis. The ejector pin is located at the end of the piston furthest from the fixture and is fixedly connected to the ejector pin drive part, which drives the ejector pin to press against or move away from the piston. The cutting tool's tip faces the circumferential surface of the piston. This simple piston turning device uses commonly available components, is easy to manufacture, has a simple structure, and is convenient to operate and maintain. It can be flexibly installed on different types of processing equipment and is especially suitable for single-piece, small-batch production and trial production.

[0004] Although the aforementioned patent can achieve chip processing of the piston, the chips generated during the cutting process are inconvenient to collect. When collecting chips through the collection box, the collection box cannot retract with the feed of the cutting tool, and the cutting tool tends to move away from the collection range of the collection box during cutting, resulting in an unsatisfactory chip collection effect.

[0005] Therefore, there is an urgent need for a turning machine for the end face of automotive pistons to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problems of safety hazards and poor chip collection during the cutting process in the prior art, which increases the difficulty of subsequent chip cleaning, and to propose a turning equipment for the end face of automobile pistons.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A turning machine for automotive piston end faces includes a base and a first support plate mounted on top of the base. A drive motor, mounted on the base via a motor mounting bracket, is located on one side of the first support plate. The output end of the drive motor passes through the first support plate and is connected to a chuck. A second feed screw, driven by a motor, is located on one side of the first support plate on the base. A first slider is mounted on the second feed screw. A telescopic material collection box is mounted on the top of the first slider. The end of the material collection box away from the second feed screw is connected to a second support plate. A cutting tool clamp is mounted on the second support plate, holding a cutting tool. A protective shell is mounted on the base.

[0009] As a preferred technical solution of this application, the collection box includes a collection bin fixedly installed on a first slider and a movable bin sliding inside the collection bin. One end of the movable bin is open and connected to the collection bin. The other end of the movable bin is fixedly connected to the second support plate. The bottom of the movable bin is inclined to the open end.

[0010] As a preferred technical solution of this application, a mounting base is installed on one side of the first slider, and a first feed screw driven by a motor is installed on the mounting base. A second slider connected to the side of the second support plate is installed on the first feed screw.

[0011] As a preferred technical solution of this application, a sealing gasket is installed on one end of the opening of the active compartment.

[0012] As a preferred technical solution of this application, an L-shaped hanging plate is installed on the outer side of the second support plate. The top of the hanging plate is connected to the cutting fluid supply tank on the top of the protective shell through a conduit. A nozzle connected to the conduit is provided on the end of the hanging plate facing the collection box.

[0013] As a preferred technical solution of this application, a sliding door is slidably connected to one side of the protective shell via a slide rail, and an observation window is installed on the sliding door.

[0014] As a preferred technical solution of this application, an L-shaped guide pipe is installed at the outer end of the collection bin, the guide pipe is connected to the collection bin, the top of the base is provided with a feed inlet below the feed outlet of the guide pipe, and the inside of the base is provided with a liquid collection box below the feed inlet.

[0015] As a preferred technical solution of this application, a filter screen is installed at an angle above the connection between the collection bin and the guide pipe.

[0016] Compared with the prior art, this utility model provides a turning machine for the end face of an automobile piston, which has the following advantages:

[0017] 1. The turning equipment for the end face of automobile pistons, by setting a telescopic collection box, can adapt to the movement of the cutting tool when the cutting tool is fed, thereby increasing the collection range of the cutting material and better collecting the chips generated during cutting. This solves the problem in the prior art that the collection box is not convenient to retract with the cutting tool feed, resulting in unsatisfactory chip collection.

[0018] 2. The turning equipment for the piston end face of the automobile is equipped with a nozzle connected to the cutting fluid supply tank. During cutting, the cutting tool can be rinsed and cooled. At the same time, the cutting fluid and the chips washed off can be collected by the collection box. The collected cutting fluid is discharged into the collection box through the guide pipe, which makes it easier to recycle the cutting fluid. This solves the problem of waste and environmental pollution caused by the inconvenience of cutting fluid recycling in the prior art. Attached Figure Description

The interior of the collection bin 16 is located above the connection point between the collection bin 16 and the guide pipe 18. A filter screen 19 is installed on the side, and the filter screen 19 is installed at an angle to seal the interface between the guide pipe 18 and the collection bin 16, preventing chips and other impurities from mixing into the cutting fluid, and also preventing chips and other impurities from clogging the connection interface; a sealing gasket 20 is installed on one end of the opening of the movable bin 15, and the sealing gasket 20 can seal the inside of the collection bin 16 when sliding, reducing the leakage of the cutting fluid collected inside. At the same time, the bottom of the movable bin 15 is inclined to the opening end, which facilitates the export of the cutting fluid collected inside.

[0034] Specifically, when the turning equipment for the piston end face of this automobile is working / in use: the workpiece to be cut is clamped by the chuck 10, and then the drive motor 8 is started to drive the chuck 10 to rotate synchronously with the workpiece. At the same time, the second feed screw 22 and the first feed screw 11 are started to perform chip cutting on the workpiece. During the cutting process, the chips generated by cutting fall into the collection box and are collected. At the same time, cutting fluid is sprayed out through the nozzle 13 to cool the cutting tool and wash off the chips. The cutting fluid and chips enter the collection box, and then the cutting fluid is guided into the liquid collection box 24 for collection through the guide pipe 18.
