Abstract

This utility model relates to the field of submersible electric pump technology, and in particular to a submersible electric pump shaft machining positioner, comprising a base and a circular block. The inner wall of the base is rotatably connected to the circular block via bearings. A V-groove is formed at the upper end of the circular block, and a positioning structure is provided on the outer wall of the circular block. Two support rods are symmetrically fixedly connected to the upper end of the circular block, and the upper ends of multiple support rods are fixedly connected to a top plate.

Description

Technical Field

[0001] This utility model relates to the field of submersible electric pump technology, specifically a submersible electric pump shaft machining positioner. Background Technology

[0002] Submersible electric pumps are particularly suitable for oilfields with high water cut, offshore platforms, and deep well development. Their efficient lifting capacity can quickly reduce bottom hole pressure and release reservoir production capacity.

[0003] For example, a shaft-type part clamping device with authorization announcement number "CN209664887U" involves placing the shaft-type part in a set position, then detecting the part with the through-beam switch transmitter and receiver, activating the first and second cylinders to rotate the first and second clamping blocks for clamping. This device boasts a high level of automation and ease of use. However, it cannot rotate the pump shaft during operation. This requires that after machining one end of the pump shaft, the shaft must be flipped and fixed before fixing the other end, resulting in a slow positioning speed during use. Utility Model Content

[0004] The purpose of this invention is to solve the problem of slow positioning of the device, and to propose a submersible electric pump shaft machining positioner.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a submersible electric pump shaft machining locator, including a base and a circular block. The inner wall of the base is rotatably connected to the circular block via bearings. The upper end of the circular block has a V-groove. The outer wall of the circular block has a positioning structure. Two support rods are symmetrically fixedly connected to the upper end of the circular block. The upper ends of multiple support rods are fixedly connected to a top plate. The surface of the support rods is provided with a clamping device.

[0007] Preferably, the positioning structure includes a horizontal plate and a bolt. One end of the horizontal plate is fixedly connected to a circular block. The horizontal plate is threadedly connected to the bolt through a threaded hole on its surface. The upper end of the base has multiple positioning holes, and the lower end of the bolt is inserted into one of the positioning holes.

[0008] Preferably, an electric push rod is fixedly connected to the lower center of the top plate.

[0009] Preferably, the pressing device includes a sliding plate and a pressing block. The sliding plate is slidably connected to a plurality of support rods through through holes in its surface. A connecting rod is fixedly connected to the upper end of the sliding plate, and a pressing block is fixedly connected to the lower end of the sliding plate.

[0010] Preferably, the upper end of the connecting rod is fixedly connected to the telescopic end of the electric push rod.

[0011] Preferably, the lower end of the pressure block is provided with a V-shaped groove.

[0012] The present invention provides a submersible electric pump shaft machining locator, which has the following advantages: Through the cooperation of the positioning structure and the clamping device, the V-groove at the lower end of the pressure block abuts against the surface of the pump shaft. With the cooperation of the pressure block and the round block, the pump shaft can be fixed. At the same time, the V-groove on the surface of the pressure block and the round block can limit the position of the pump shaft. One end of the pump shaft can be machined by an external cutting or grinding device. After one end of the pump shaft is machined, the operator rotates the bolt so that the bolt is no longer inserted into the positioning hole. At the same time, the operator turns the round block to rotate, so that the round block can drive the pump shaft on the surface to rotate. When it is rotated to a specified angle, the operator can turn the bolt again so that the bolt can be inserted into the positioning hole again, so that the angle of the round block can be fixed, realizing the rotation of the pump shaft and facilitating the machining of the other end of the pump shaft.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] See attached document Figure 1-6In this embodiment, a submersible electric pump shaft machining locator includes a base 1 and a circular block 3. The inner wall of the base 1 is rotatably connected to the circular block 3 via bearings. A V-groove is provided at the upper end of the circular block 3. A positioning structure 2 is provided on the outer wall of the circular block 3. Two support rods 4 are symmetrically fixedly connected to the upper end of the circular block 3. The upper ends of the multiple support rods 4 are all fixedly connected to the top plate 6. A pressing device 7 is provided on the surface of the support rods 4. An electric push rod 5 is fixedly connected to the center of the lower end of the top plate 6. The electric push rod 5 is selected to have a self-locking function according to actual needs. The upper end of the connecting rod 701 is fixedly connected to the telescopic end of the electric push rod 5. A V-groove is provided at the lower end of the pressure block 703.

[0022] The positioning structure 2 includes a horizontal plate 201 and a bolt 202. One end of the horizontal plate 201 is fixedly connected to the round block 3. The horizontal plate 201 is threadedly connected to the bolt 202 through a threaded hole on its surface. The upper end of the base 1 is provided with multiple positioning holes 203. The lower end of the bolt 202 is inserted into one of the positioning holes 203.

[0023] The clamping device 7 includes a sliding plate 702 and a pressure block 703. The sliding plate 702 is slidably connected to a plurality of support rods 4 through through holes opened on its surface. A connecting rod 701 is fixedly connected to the upper end of the sliding plate 702, and a pressure block 703 is fixedly connected to the lower end of the sliding plate 702.

[0024] Working principle:

[0025] When positioning the submersible pump shaft:

[0026] The operator places the pump shaft into the V-groove on the surface of the circular block 3, so that the pump shaft can be limited by the V-groove. At the same time, the operator controls the electric push rod 5 to work, so that the telescopic end of the electric push rod 5 extends and drives the slide plate 702 to move synchronously through the connecting rod 701. The slide plate 702 can drive the pressure block 703 to move downward, so that the V-groove at the lower end of the pressure block 703 abuts against the surface of the pump shaft. With the cooperation of the pressure block 703 and the circular block 3, the pump shaft can be fixed. At the same time, the V-groove on the surface of the pressure block 703 and the circular block 3 can limit the position of the pump shaft. One end of the pump shaft can be processed by external cutting or grinding equipment.

[0027] Rotation process:

[0028] After one end of the pump shaft is machined, the operator rotates bolt 202 so that bolt 202 is no longer inserted into the positioning hole 203. At the same time, the operator turns the round block 3 to rotate, so that the round block 3 can drive the pump shaft on the surface to rotate. When it is rotated to a specified angle, the operator can turn bolt 202 again so that bolt 202 can be inserted into the positioning hole 203 again, so that the angle of the round block 3 can be fixed, realizing the rotation of the pump shaft, which facilitates the machining of the other end of the pump shaft.

[0029] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
