Description

Auxiliary tool for plunger sanding process
Technical Field
The utility model relates to the technical field of numerical control lathe fixtures, in particular to an auxiliary tool for a plunger sanding process.
Background
The plunger component shown in fig. 1 requires a sanding process because of its high surface roughness requirement. In the prior art, a three-jaw chuck on a lathe is generally adopted to clamp the part, and a worker manually sands the part after clamping the part on the lathe. By the method, a worker cannot sand the position where the three-jaw chuck is contacted with the part, cannot finish manual sanding at one time, needs to perform secondary clamping and sanding, increases the workload of the worker, and reduces the working efficiency; in addition, if foreign matters exist in the process of clamping the part by the three-jaw chuck, the part can be damaged by clamping, and the product quality is reduced.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems mentioned in the above, the utility model provides an auxiliary tool for a plunger sanding process, which is simple in structure and convenient to operate, can clamp a plunger part on a lathe, is convenient for workers to finish manual sanding at one time, improves the production efficiency, enables a three-jaw chuck to indirectly clamp the part, effectively prevents the part from being damaged by clamping, and improves the product quality.
The utility model provides an assist utensil for plunger sand light technology which characterized in that: the auxiliary tool comprises a positioning block, the rear end of the positioning block is used for being clamped by a three-jaw chuck, the front end of the positioning block is connected with the rear end of the material ejecting head through threads, the front end of the material ejecting head is a conical surface, a limiting baffle is fixed on the rear side of the conical surface of the material ejecting head, and the limiting baffle is perpendicular to the axial lead of the material ejecting head.
Furthermore, the front end of the material ejection head is provided with a plurality of sizes which are matched with plunger parts of corresponding models.
Furthermore, the front end of the material ejection head and the surface of the limit baffle are provided with cushion pads.
Furthermore, the front end of the positioning block can also be connected with the rear end of the ejector through a clamping groove clamping block.
Furthermore, the positioning block and the material ejecting head are both cylindrical.
The utility model has the beneficial effects that:
1. according to the utility model, the rear end of the positioning block is clamped and aligned by the three-jaw chuck, the ejector head is inserted into one end of the plunger part and limited by the limiting baffle, and finally the ejector pin on the lathe is used for ejecting the other end of the plunger part, so that the part is clamped.
2. According to the plunger piston ejecting device, the positioning block and the ejection head are of detachable structures, so that workers can replace the ejection heads with different front end sizes according to plunger parts with different models and sizes, the operation is convenient, and the production efficiency is further improved.
3. The front end of the material ejection head and the surface of the limiting baffle are provided with the buffer pads, so that the part is further prevented from being clamped and damaged, and the product quality is improved.

Detailed Description
The present invention will be further described with reference to the following examples.
The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model. The conditions in the embodiments can be further adjusted according to specific conditions, and simple modifications of the method of the present invention based on the concept of the present invention are within the scope of the claimed invention.
Referring to fig. 2, an auxiliary tool for a plunger sanding process is characterized in that: the auxiliary tool comprises a positioning block 1, the rear end of the positioning block 1 is used for being clamped tightly by a three-jaw chuck, the front end of the positioning block 1 is connected with the rear end of a material ejecting head 2 through threads, the front end of the material ejecting head 2 is a conical surface 21, a limiting baffle 22 is fixed on the rear side of the conical surface 21 of the material ejecting head 2, the limiting baffle 22 is perpendicular to the axial lead of the material ejecting head 2, and the positioning block 1 and the material ejecting head 2 are cylindrical. This assistive tool is tight alignment by the tight clamp of three-jaw chuck through the rear end of locating piece 1 earlier, then inside inserting plunger part one end with ejector pin head 2, and utilize limit baffle 2 to carry on spacingly, use the thimble on the lathe to withstand the other end of plunger part at last, and then accomplish the clamping of this part, the workman of being convenient for once only accomplishes manual sand light, and improved production efficiency, and make the non-direct clamp of three-jaw chuck tightly this part, effectively prevented this part from being hindered by the clamp, improved product quality.
The front end of the positioning block 1 can be connected with the rear end of the ejector head 2 through threads and can also be connected with the rear end of the ejector head 2 through a clamping groove clamping block, the front end of the ejector head 2 is provided with a plurality of sizes, and the front end of the ejector head 2 is matched with plunger parts of corresponding models. The positioning block 1 and the material ejecting head 2 are of a detachable structure, so that workers can replace the material ejecting heads with different front end sizes according to plunger parts with different model sizes, the operation is convenient, and the production efficiency is further improved.
The front end of the material ejection head 2 and the surface of the limit baffle 22 are provided with cushion pads 23, so that the parts are further prevented from being clamped and damaged, and the product quality is improved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
