Description

Technical Field

[0001] The utility model belongs to the technical field of transport pump production, and particularly relates to a pump casing fixing device. Background Art

[0002] The pump casing provides a solid protective shell for the pump's internal components, preventing damage to the delicate components from external dust, impurities, and possible collisions. It also provides support for key components such as the impeller and shaft, ensuring they maintain a stable position and correct working posture during operation.

[0003] During pump operation, the pump casing plays a crucial role in supporting and protecting the pump, while the sealing ring is a key component in ensuring the pump's tightness and preventing fluid leakage. Carefully grooved pump casings provide a dedicated space for the sealing ring. The size and shape of this groove are precisely designed to perfectly match the sealing ring, ensuring a stable installation. When the pump is operating, the sealing ring fits tightly within the groove, effectively preventing fluid from leaking through the connection between the pump casing and other components. Whether handling high-temperature, high-pressure fluids or corrosive media, the combination of the appropriate sealing ring and pump casing grooves delivers excellent sealing performance, ensuring efficient and stable pump operation. When grooving, the pump casing must first be securely fixed in place using a suitable fixture, such as a clamp or a dedicated mounting platform. This prevents the pump casing from moving or shaking during the grooving process, ensuring accurate and high-quality grooving.

[0004] Existing pump casing slotting fixtures have certain limitations in practical use. When slotting a pump casing, the fixture securely holds the pump casing in place to ensure stability and precision. However, this fixing method prevents other operations during the slotting process. The casing must be removed from the fixture after slotting is complete before the next pump casing can be installed. This significantly impacts work efficiency. Therefore, a pump casing fixture is proposed. Utility Model Content

DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the embodiments.

[0024] The following examples are intended to illustrate the present invention and are not intended to limit the scope of protection of the present invention. The conditions in the examples may be further adjusted according to specific conditions. Simple improvements to the method of the present invention based on the concept of the present invention fall within the scope of protection claimed by the present invention.

[0025] See also Figure 1-5 The utility model provides a pump casing fixing device, including a fixing platform 10, with supporting feet 110 provided on both sides of the bottom of the fixing platform 10, and the supporting feet 110 are used to make the top of the fixing platform 10 at a suitable height for easy operation by staff.

[0026] See also Figure 1 and Figure 2A No. 1 groove 101 is provided on the top of the fixed platform 10, and a No. 2 groove 102 is provided at the bottom on both sides of the inner cavity of the No. 1 groove 101. A threaded rod 120 is horizontally arranged in the No. 1 groove 101, and one side of the threaded rod 120 is installed on the output shaft of the drive motor 130. The drive motor 130 is installed on the right side of the fixed platform 10. Two moving blocks 140 are threadedly sleeved on the threaded rod 120, and a No. 1 protrusion 1401 is provided at the bottom on both sides of the moving block 140. The No. 1 protrusion 1401 is slidably set in the No. 2 groove 102; by starting the drive motor 130, the output shaft of the drive motor 130 drives the threaded rod 120 to rotate, and the two moving blocks 140 can move left and right under the drive of the threaded rod 120 and the limit of the No. 2 groove 102.

[0027] See also Figure 1 、 Figure 3 and Figure 4 , a fixing assembly 20 is provided on each of the two moving blocks 140, and the fixing assembly 20 includes a U-shaped member 210, the bottom of the U-shaped member 210 is connected to the top of the moving block 140, and limiting grooves 2101 are provided on both sides of the U-shaped member 210. Two clamping members 220 are provided on the U-shaped member 210, and the tops of the two clamping members 220 close to each other are arranged in an arc shape, which facilitates the quick placement of the pump casing between the two clamping members 220;

[0028] The sides of the two clamping members 220 that are close to each other can be configured to have a shape that matches the pump casing, so as to better clamp the pump casing.

[0029] A No. 3 groove 2201 is provided at the bottom of the clamping member 220, and a No. 2 protrusion 2202 is provided on both sides of the inner cavity of the No. 3 groove 2201. The No. 2 protrusion 2202 is slidably provided in the limiting groove 2101, so that the two clamping members 220 can only move horizontally.

[0030] The two clamping parts 220 are connected to the side away from each other with a No. 1 connecting rod 231 and a No. 2 connecting rod 232 respectively. The No. 1 connecting rod 231 is in a 'T' shape, and the No. 2 connecting rod 232 is in a 'stem' shape, which limits the left and right movement distance of the two clamping parts 220 to avoid excessive movement.

[0031] Connecting rod No. 1 231 and connecting rod No. 2 232 can both move left and right and be inserted into the U-shaped part 210. A plurality of elastic parts 240 are provided between the side of the two clamping parts 220 that are away from each other and the U-shaped part 210. The two elastic parts 240 provide a force to move closer to each other, so that the pump casing is prevented from being clamped at the back, and the pump casing is prevented from being offset when the fixing component 20 moves.

[0032] See also Figure 1 and Figure 5The fixed platform 10 is located in the middle of the No. 1 slot 101 and is close to the No. 1 connecting rod 231. A pushing mechanism 30 is provided on one side, including an electric push rod 310 and a pushing block 320. The pushing block 320 is L-shaped. The pushing block 320 is movably sleeved on two limit rods 330. The two limit rods 330 are arranged horizontally. The limit rod 330 is arranged horizontally in the No. 4 slot 401 at the top of the mounting seat 40.

[0033] The working principle and use process of the utility model are as follows: the device is placed below the slotting device;

[0034] The pump casing is placed between the two clamping members 220. At this time, the elastic member 240 on the side where the two clamping members 220 are away from each other is in a compressed state. By starting the drive motor 130, the output shaft of the drive motor 130 drives the threaded rod 120 to rotate. The two moving blocks 140 can be alternately moved to the bottom of the slotting device under the drive of the threaded rod 120 and the limit of the second slot 102. Then, the electric push rod 310 is started, and the electric push rod 310 pushes the pushing block 320 to move. The pushing block 320 pushes the first connecting rod 231 to move. When the second connecting rod 231 cannot move, the pushing stops. At this time, the pump casing is fixed and cannot move.

[0035] The alternating use of the two fixing components allows one fixing component to process the pump casing while the other fixing component can be used to remove or install the pump casing. This avoids wasted time waiting for installation or removal of the pump casing, fully utilizes processing time, and greatly improves overall work efficiency.
