Description

[Technical field]

[0001] The utility model relates to the technical field of pump valve tube processing, in particular to a pump valve tube clamp shell type processing device. [Background Technology]

[0002] At present, the existing pump and valve pipe processing uses a three-claw or four-claw chuck to clamp the middle circular surface of the pump and valve pipe, and a milling machine or a machining center to process the two end faces and the inner hole. After completion, the threaded hole position is repositioned to process the threaded hole. This processing method is easy to clamp the pump and valve pipe when clamping it, and because the length of the pump and valve pipe is inconsistent, the length of the three-claw or four-claw is too short or too long, which makes it difficult to clamp during clamping; in addition, the processing of the threaded hole needs to be repositioned, and the accuracy of positioning the threaded hole depends on the operator's responsibility and the working hours are long, and the wall thickness of the thread is uneven. Therefore, the processing quality of the traditional processing method is unstable, resulting in unnecessary scrapping, and increasing material costs and labor costs. [Contents of the utility model]

[0003] The purpose of the utility model is to solve the above-mentioned shortcomings and provide a pump valve tube clamp shell type processing device, which can shorten the time of each correction, clamping and fixing, improve the work efficiency and processing accuracy, and is suitable for pump valve tubes of different lengths, solving the problems of uneven wall thickness caused by poor clamping and deviation of hole positions in previous processing.

[0004] In order to achieve the above-mentioned purpose, a pump valve tube clamp shell processing device is designed, comprising a chuck 1, on which a positioning groove 11 and a positioning groove 2 12 are arranged, the positioning groove 11 and the positioning groove 2 12 are both arranged to extend radially and are located on the same diameter, the positioning groove 11 is movably installed with a welding extension claw 1 2a, the positioning groove 2 12 is movably installed with a welding extension claw 2b, the welding extension claw 1 2a is opposite to the welding extension claw 2b It is arranged that the other end of the welding extended two claws 2a is cooperated and connected with the upper clamp 3 of the pump valve tube, and the other end of the welding extended two claws 2b is cooperated and connected with the lower clamp 5 of the pump valve tube. The upper clamp 3 of the pump valve tube and the lower clamp 5 of the pump valve tube are both semicircular structures, and the upper clamp 3 of the pump valve tube and the lower clamp 5 of the pump valve tube are arranged opposite to each other. The upper clamp 3 of the pump valve tube and the lower clamp 5 of the pump valve tube move up and down with the welding extended two claws 2a and the welding extended two claws 2b respectively to clamp or release the pump valve tube 4.

[0005] Furthermore, semicircular grooves are provided on the inner walls of the upper clamp 3 and the lower clamp 5 of the pump valve tube, and the semicircular grooves coincide with the outer circular surface in the middle of the pump valve tube 4. After the upper clamp 3 and the lower clamp 5 of the pump valve tube move up and down, the semicircular grooves clamp or release the pump valve tube 4, which not only avoids the phenomenon that the pump valve tube is easily clamped when the middle circular surface of the pump valve tube is clamped with a three-jaw or four-jaw chuck in the traditional processing device, but also improves the processing accuracy.

[0006] Furthermore, a slot 35 is provided on the outer circumferential surface of the pump valve tube clamp 3, and the slot 35 is arranged to extend axially. The welded extended two claws 2a are inserted into the slot 35 and welded to the pump valve tube clamp 3 as a whole, so that the positioning is more accurate and the processing efficiency is improved.

[0007] Furthermore, a circular hole 31 and a circular hole 33 are provided on the outer circumferential surface of the clamp 3 on the pump valve tube, a drill sleeve 32 is embedded in the circular hole 31, and a drill sleeve 34 is embedded in the circular hole 33. The drill sleeve 32 and the drill sleeve 34 are respectively used for positioning and processing the threaded hole 41 and the threaded hole 42 of the pump valve tube 4, thereby further ensuring the positioning size and processing accuracy of the threaded hole.

[0008] Furthermore, a second slot 53 is provided on the outer circumferential surface of the pump valve tube lower clamp 5, and the second slot 53 is arranged to extend axially. The two welding extended claws 2b are inserted into the second slot 53 and welded to the pump valve tube lower clamp 5 as a whole, so that the positioning is more accurate and the processing efficiency is improved.

[0009] Furthermore, a circular hole 3 51 is provided on the outer circumferential surface of the pump valve tube lower clamp 5, and a drill sleeve 3 52 is embedded in the circular hole 3 51. The drill sleeve 3 52 is used to position and process the threaded hole 3 43 of the pump valve tube 4, further ensuring the positioning size and processing accuracy of the threaded hole.

[0010] Furthermore, the chuck 1 is provided with an axial hole at its center and is connected to the main shaft of the machining center through the axial hole. The chuck 1 is provided with a correction hole on its outer circumferential surface and the runout accuracy of the chuck 1 and the main shaft is corrected through the correction hole.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] (1) The utility model provides a pump valve tube clamp shell type processing device, which improves the processing efficiency and processing accuracy by improving the processing tooling;

[0013] (2) The utility model is characterized in that, except for the need to calibrate the tooling when installing the tooling, the pump valve tube can be clamped once to complete the processing of the end face, inner hole and threaded hole, which can ensure the verticality of the end face and the inner hole, and also ensure the positioning size and processing accuracy of the threaded hole;

[0014] (3) The utility model greatly shortens the time for each calibration, clamping and fixing, improves work efficiency, and is applicable to pump valve pipes of different lengths;

[0015] (4) The utility model has a reasonable design. As long as the runout accuracy between the chuck and the lathe spindle is corrected when the chuck is installed, the concentricity and runout accuracy of the holes at both ends of the pump valve tube and the position accuracy of the threaded holes can be ensured when processing the pump valve tube, thereby improving the efficiency and accuracy of the pump valve tube processing;

[0016] (5) The utility model solves the problems of difficult clamping and uneven wall thickness caused by hole deviation in the past, and also avoids tool vibration, which is worthy of popularization and application. [Drawings]
