Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum pump auxiliary tooling, and in particular relates to a mounting seat for a vacuum pump. Background Art

[0002] A vacuum pump is a device or equipment that uses mechanical, physical, chemical or physicochemical methods to evacuate the container to obtain a vacuum;

[0003] The utility model application number CN201921962731.9 (publication number CN210919394U) discloses a fixing device for a vertical vacuum pump. The device places the pump body on the inner bottom surface of a U-shaped plate, rotates the screw rod, and causes the annular plate to rotate inside the circular groove, thereby allowing the screw rod to rotate better. Due to the rotation of the screw rod, the screw rod rotates and moves inside the threaded hole, thereby causing the first clamping plate to move.

[0004] The above patent only clamps the two sides of the circumferential surface of the vacuum pump. If the clamping plate does not fit the curvature of the vacuum pump, the vacuum pump will shake along the front and back sides of its circumferential surface, resulting in unstable installation. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a mounting base for a vacuum pump, which improves the contact with the circumferential surface of the vacuum pump and can stably mount the vacuum pump.

[0006] The utility model is achieved in this way:

[0007] The utility model provides a mounting base for a vacuum pump, comprising a base frame, wherein hydraulic rods are fixedly mounted at the four corners of the bottom wall of the base frame, the movable ends of the hydraulic rods extend downward, and universal wheels are fixedly mounted at the ends thereof, and support legs are fixedly mounted on the bottom wall of the base frame and between two universal wheels on the same side;

[0008] Two horizontal plates arranged side by side in front and back are fixedly mounted on the top wall of the chassis, a support plate is fixedly mounted on the left and right ends of the two horizontal plates, and clamping components are symmetrically arranged on the two support plates;

[0009] The clamping assembly includes bearing seats fixedly installed at the front and rear ends of the support plate, a rotating shaft is rotatably connected to the bearing in the bearing seat, one end of the swing arm is fixedly installed at both ends of the rotating shaft through a tightening sleeve, and a connecting plate is fixedly installed on the inner side wall of the other end of the two swing arms on the same side, and a plurality of clamping claws that contact the vacuum pump are provided on the connecting plate.

[0010] On the basis of the above technical solution, the mounting base of a vacuum pump of the present invention can also be improved as follows:

[0011] Furthermore, the connecting plate is provided with a plurality of threaded through holes, and the clamping claw is provided with two threaded holes on one side close to the connecting plate, and the threaded holes and the threaded through holes are connected together with bolts.

[0012] Furthermore, one end of a rotating plate is fixedly mounted on a surface of the swing arm away from the bearing seat, and the other ends of the rotating plates on both sides are hinged to each other through hinge columns.

[0013] Furthermore, a sliding groove perpendicular to the center line of the rotating shaft is opened in the middle of the right support plate, and an ear plate is slidably connected in the sliding groove, and one end of the ear plate is fixedly installed on the rotating shaft.

[0014] Furthermore, a transverse telescopic cylinder is fixedly mounted on the support plate, a hinge seat is fixedly mounted on the movable end of the transverse telescopic cylinder, and the other end of the ear plate is hinged on the hinge seat.

[0015] Furthermore, a vertical telescopic cylinder is fixedly mounted on one end of the two support plates close to each other, and the movable ends of the two vertical telescopic cylinders extend upward, and a pressure plate in contact with the vacuum pump is fixedly mounted on the end.

[0016] Compared with the prior art, the beneficial effects of the vacuum pump mounting base provided by the present invention are:

[0017] The symmetrical arrangement of the clamping assembly and the pressing plate, the inward movement of the clamping assembly and the vertical movement of the pressing plate make it suitable for vacuum pumps of various sizes. The cooperation between the clamping assembly and the pressing plate can increase the contact with the circumferential surface of the vacuum pump and improve the stability of the installation.

[0018] By setting up two rotating plates with one end hinged to each other and the other end fixed to the swing arm, the swing arms of the two clamping assemblies can drive the connecting plates to move synchronously under the action of a power (i.e. a horizontal telescopic cylinder).

[0031] like Figure 1-4 As shown, the utility model provides a mounting base for a vacuum pump, comprising a base frame 1, wherein hydraulic rods 11 are fixedly mounted at the four corners of the bottom wall of the base frame 1, the movable ends of the hydraulic rods 11 extend downward, and universal wheels 12 are fixedly mounted at the ends thereof, and support legs 13 are fixedly mounted on the bottom wall of the base frame 1 and between the two universal wheels 12 on the same side;

[0032] Two horizontal plates 10 arranged side by side are fixedly mounted on the top wall of the chassis 1. A support plate 2 is fixedly mounted on the left and right ends of the two horizontal plates 10. Clamping components are symmetrically arranged on the two support plates 2.

[0033] The clamping assembly includes a bearing seat 21 fixedly mounted on the front and rear ends of the support plate 2. A rotating shaft 23 is rotatably connected to the bearing seat 21 through a bearing 22. One end of a swing arm 24 is fixedly mounted on both ends of the rotating shaft 23 through a tightening sleeve. A connecting plate 25 is fixedly mounted on the inner side wall of the other end of the two swing arms 24 on the same side. The connecting plate 25 is provided with a plurality of clamping claws 26 that contact the vacuum pump.

[0034] Optionally, in the above technical solution, a plurality of threaded through holes 251 are provided on the connecting plate 25 , and two threaded holes 261 are provided on one side of the clamping claw 26 close to the connecting plate 25 , and bolts are connected to the threaded holes 261 and the threaded through holes 251 .

[0035] Optionally, in the above technical solution, one end of a rotating plate 31 is fixedly mounted on a surface of the swing arm 24 away from the bearing seat 21 , and the other ends of the rotating plates 31 on both sides are hinged to each other through a hinge column 32 .

[0036] Optionally, in the above technical solution, a slide groove 33 perpendicular to the center line of the rotating shaft 23 is opened in the middle of the right support plate 2, and an ear plate 34 is slidably connected in the slide groove 33, and one end of the ear plate 34 is fixedly mounted on the rotating shaft 23.

[0037] Optionally, in the above technical solution, a transverse telescopic cylinder 35 is fixedly mounted on the support plate 2 , a hinge seat 36 is fixedly mounted on the movable end of the transverse telescopic cylinder 35 , and the other end of the ear plate 34 is hinged on the hinge seat 36 .

[0038] Optionally, in the above technical solution, a vertical telescopic cylinder 41 is fixedly installed on one end of the two support plates 2 close to each other, and the movable ends of the two vertical telescopic cylinders 41 extend upward, and a pressure plate 42 in contact with the vacuum pump is fixedly installed on the end.

[0039] Among them, the sum of the height of the movable end of the hydraulic rod 11 when fully retracted and the height of the universal wheel 12 is less than the height of the support leg 13, and the sum of the height of the movable end of the hydraulic rod 11 when fully extended and the height of the universal wheel 12 is greater than the height of the support leg 13.

[0040] The diameter of the vacuum pump suitable for the mounting seat must be larger than the distance between the two pressure plates 42 and smaller than the distance between the top ends of the clamping claws 26 on both sides when the transverse telescopic cylinder 35 is extended to the maximum limit.

[0041] The travel of the movable end of the transverse telescopic cylinder 35 is limited by the length of the slide slot 33 .

[0042] The threaded hole 261 is not provided as a through hole to prevent the bolt from protruding from the side where the clamping claw 26 contacts the vacuum pump, thereby affecting the clamping of the vacuum pump.

[0043] When in use, the vacuum pump is placed on the two pressing plates 42 so that the bottom end of its circumferential surface contacts the two pressing plates 42. The number and position of the clamping claws 26 are adjusted according to the circumferential length of the vacuum pump. The redundant clamping claws 26 are removed by unscrewing the bolts. The clamping claws 26 on both sides are retracted through the clamping assembly to clamp the vacuum pump horizontally. The vertical telescopic cylinder 41 is started to extend its movable end to drive the pressing plate 42 upward, and the vacuum pump is vertically clamped through the pressing plate 42 and the clamping claws 26.

[0044] When movement is required, the hydraulic rod 11 is activated to extend its movable end until the universal wheel 12 is moved below the bottom wall of the support leg 13. The sliding of the universal wheel 12 can drive the vacuum pump on the chassis 1 to move;

[0045] The clamping assembly is used as follows: the transverse telescopic cylinder 35 is activated to retract its movable end, driving one end of the ear plate 34 to move transversely. The other end of the ear plate 34 drives the rotating shaft 23 to rotate. The rotation of the rotating shaft 23 drives the swing arm 24 to rotate in the same manner. The swing arms 24 on both sides move synchronously through the two hinged connecting plates 25, thereby causing the clamping claws 26 on both sides to retract simultaneously to clamp the vacuum pump.

[0046] The vertical rod of the clamping claw 26 abuts against the side surface of the vacuum pump, the horizontal rod of the clamping claw 26 abuts against the top surface of the vacuum pump, and the pressure plate 42 abuts against the bottom surface of the vacuum pump, clamping multiple parts of the circumferential surface of the vacuum pump to improve the stability of the installation.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
