Description

Technical Field

[0001] The utility model belongs to the technical field of pump main shaft processing, in particular to a grinding table for the pump main shaft to rotate and swing. Background Art

[0002] The pump spindle is the core component of the pump, responsible for transmitting the rotational motion of the motor to the pump impeller, so that the impeller rotates and the liquid is transported. The ball socket on the pump spindle is used to cooperate with the rolling element (such as ball or roller) of the bearing to support the rotation of the spindle.

[0003] In the prior art, a ball socket is automatically ground by a grinder. For example, the patent with the authorization announcement number CN 203266383U discloses a ball socket grinder, on which a rotating shaft is provided on the workbench. During grinding, the rotating shaft drives the ball socket workpiece to rotate around the workbench. In this way, the smoothness, shape and size accuracy of the ball socket after grinding are not ideal. Utility Model Content

[0004] Based on this, in order to solve the above technical problems, a grinding table with a pump main shaft rotating and swinging is provided.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A grinding table with a pump main shaft rotating and swinging, characterized in that it comprises:

[0007] A platform, wherein the platform surface of the platform has mounting through holes in the up-and-down directions;

[0008] A swing ring, the swing ring is arranged in the mounting through hole, and is connected to the mounting through hole in an up-and-down swinging manner via a first axis along the radial direction of the mounting through hole;

[0009] A fixing seat for fixing the pump main shaft so that the ball socket faces upward, the fixing seat is arranged in the swing ring, and is connected to the swing ring through a second axis along the radial direction of the mounting through hole, and the second axis is 90 degrees to the first axis;

[0010] The driving mechanism is used for driving the lower part of the fixing seat to reciprocate on a horizontal circular path. The driving mechanism is arranged in the platform body and connected with the lower part of the fixing seat.

[0011] The grinding table of the present utility model is composed of a table body, a swing ring, a fixed seat and a driving mechanism. Driven by the driving mechanism, the lower part of the fixed seat can reciprocate on a horizontal circular path. Cooperating with the swing of the swing ring, the spherical socket surface of the pump main shaft will swing and rotate along the center line of the installation through hole, so that the spherical sockets on the spherical socket surface achieve uniform height changes and rotational movements. With the self-rotation of the grinding rod, uniform grinding of the inner wall of the spherical socket can be realized. The surface finish, shape and dimensional accuracy of the spherical socket are high, improving the matching degree with the bearing rolling elements. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 2 is a schematic structural diagram of the driving mechanism of the present utility model. SPECIFIC EMBODIMENTS

[0015] The embodiments of the present utility model will be described below in conjunction with the accompanying drawings of the specification. It should be noted that the embodiments involved in this specification are not exhaustive and do not represent the only embodiments of the present utility model. The following corresponding embodiments are only for clearly explaining the utility model content of the patent of the present utility model, and do not limit its embodiments. For those of ordinary skill in the art, different forms of changes and modifications can be made on the basis of the description of this embodiment. Any changes or modifications that belong to the technical concept and utility model content of the present utility model and are obvious are also within the protection scope of the present utility model.

[0016] As Figure 1 and Figure 2 shown, the embodiment of the present utility model provides a grinding table for the rotation and swing of a pump main shaft, including a table body 1110, a swing ring 1120, a fixed seat 1130 and a driving mechanism 1140.

[0017] The tabletop 1111 of the table body 1110 has an installation through hole 1111a in the up-down direction.

[0018] The swing ring 1120 is concentrically arranged in the installation through hole 1111a, and is connected to the installation through hole 1111a by two first shafts 1150 that are symmetric in the front and back. The direction of the first shaft 1150 is the radial direction of the installation through hole 1111a, so as to realize the up-down swing connection between the swing ring 1120 and the installation through hole 1111a.

[0019] As Figure 2As shown, the fixing seat 1130 has a fixing groove 1131 for fixing the pump main shaft so that the ball socket faces upward. The fixing seat 1130 is concentrically arranged in the swing ring 1120, and is connected to the swing ring 1120 through two left-right symmetrical second shafts 1160. The direction of the second shaft 1160 is the radial direction of the mounting through hole 1111a, so as to realize the up and down swing connection between the fixing seat 1130 and the swing ring 1120, see Figure 1 .

[0020] It is understandable that the two first axes 1150 and the two second axes 1160 are not limited to be arranged front-to-back and left-to-right, as long as they are at 90 degrees.

[0021] The driving mechanism 1140 is used to drive the lower portion of the fixing seat 1130 to reciprocate on a horizontal circular path, and the circular path coincides with the center line of the mounting through hole 1111 a.

[0022] The driving mechanism 1140 is disposed in the platform 1110. Figure 2 As shown, it includes a transmission arm 1141, a motor 1142 and a transmission rod 1143. The transmission arm 1141 is arranged horizontally. The motor 1142 is used to drive the transmission arm 1141 to rotate horizontally. The motor 1142 is connected to the fixed end of the transmission arm 1141. The free end of the transmission arm 1141 forms a U-shaped portion 1141a. The lower end of the transmission rod 1143 forms a hinge joint 1143a. The hinge joint 1143a and the U-shaped portion 1141a are hinged up and down through a horizontal hinge shaft 1144. The upper end of the transmission rod 1143 is connected to the lower part of the fixed seat 1130.

[0023] Driven by the driving mechanism 1140, the lower part of the fixed seat 1130 reciprocates on a horizontal circular path. In conjunction with the swing of the swing ring 1120, the ball socket surface of the pump main shaft will rotate and swing along the center line of the mounting through hole 1111a, so that the ball socket on the ball socket surface can achieve uniform rotational motion and height changes.

[0024] From the above, it can be seen that the embodiment of the utility model provides a grinding table for rotating and swinging the pump main shaft, which is composed of a table body, a swing ring, a fixed seat and a driving mechanism. Driven by the driving mechanism, the lower part of the fixed seat can reciprocate on a horizontal circular path. In conjunction with the swing of the swing ring, the ball socket surface of the pump main shaft will swing and rotate along the center line of the mounting through hole, so that the ball socket on the ball socket surface can achieve uniform height changes and rotational movement. With the cooperation of the self-rotation of the grinding rod, uniform grinding of the inner wall of the ball socket can be achieved. The ball socket has high smoothness, shape and size accuracy, which improves the compatibility with the bearing rolling elements.

[0025] Obviously, those skilled in the art can make various changes and modifications to this application without departing from the scope of this application. Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalent technologies, this application is also intended to cover these changes and modifications.
