[0002] The vacuum pump is mainly composed of a cavity, a partition, an active rotor, a driven rotor, an oil chamber, a pump cover, a motor and other parts. It is assembled in the pump cavity. Under the drive of the motor, the active rotor and the driven rotor cooperate to rotate at high speed to continuously suck the external gas into the pump cavity and then release it. The periodic change of the volume of the pump cavity is used to achieve the effect of vacuuming. At present, the vacuum pump is mainly produced and assembled manually: the vacuum pump cavity is placed on a horizontal workbench and the partition, active rotor and driven rotor and other parts are manually assembled on the cavity in turn. Since there are many parts that constitute the vacuum pump and different parts need to be assembled on different end faces of the vacuum pump cavity, the vacuum pump cavity needs to be turned over several times during the assembly operation to process each end face one by one.

[0003] In the existing vacuum pump assembly operation, the vacuum pump chamber is mostly manually flipped. This method has the following disadvantages: 1) The vacuum pump chamber is often large in size and has a certain weight. The assembly operation relies solely on manual flipping, which is labor-intensive and prone to safety accidents; 2) The manual flipping operation is time-consuming and labor-intensive, and the production efficiency is low due to the limitation of manpower speed; 3) It requires a large amount of human resources and has high production costs. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an auxiliary flipping device for vacuum pump assembly. The driving unit drives the clamp assembly to perform a fixed-axis rotation action at a preset angle and orientation, which can drive the vacuum pump base to be synchronously flipped and adjusted to a preset angle and orientation along with the fixed-axis rotation action of the clamp assembly, replacing the manual flipping operation, which not only effectively reduces the occurrence of safety accidents and saves labor costs, but also saves time and effort, and greatly improves production efficiency.

[0005] In order to achieve the above-mentioned purpose, the utility model provides an auxiliary flipping device for vacuum pump assembly, including a vacuum pump base, a support seat, and a clamp assembly arranged on the support seat and used to clamp and fix the vacuum pump base, wherein the clamp assembly is also configured with a driving unit for driving it to perform a fixed-axis rotation action, and the vacuum pump base is synchronously flipped and adjusted to a preset angle orientation as the clamp assembly rotates along the fixed axis.

[0006] Furthermore, the clamp assembly comprises a first clamp arm and a second clamp arm which are arranged opposite to each other and are detachably connected to each other, and the first clamp arm and the second clamp arm respectively clamp and press at two opposite ends of the vacuum pump base.

[0007] Furthermore, the driving unit includes a reduction motor arranged on the support seat, and a transmission shaft having one end connected to the output end of the reduction motor and the other end drivingly connected to the clamp assembly.

[0008] Furthermore, it also includes two bearing seats which are respectively arranged on both sides of the clamp assembly and are rotatably connected thereto.

[0009] Furthermore, it also includes a control component for controlling the driving unit to drive the clamp assembly to rotate along a fixed axis, and the angular orientation and start and stop actions, wherein the control component includes a plurality of control units.

[0010] Furthermore, the clamp assembly is provided with a plurality of fixing holes for preset screws to pass through and connect.

[0011] Furthermore, it also includes a pulley fixed at the bottom of the support seat and used to move the support seat.

[0012] The utility model adopts the above-mentioned scheme, and its beneficial effect is that the vacuum pump base can be firmly connected to the clamp assembly and rotated together with the clamp assembly to an angle that is convenient for the assembler to perform the assembly operation, which greatly facilitates the subsequent assembly operations of the remaining components; and replaces the manual flipping operation in the traditional vacuum pump assembly process, which not only effectively reduces the occurrence of safety accidents and saves labor costs, but also saves time and effort, and greatly improves assembly efficiency.

DETAILED DESCRIPTION

[0032] In order to facilitate the understanding of the present invention, the present invention is described more comprehensively with reference to the accompanying drawings. The accompanying drawings show preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood. It should be noted that the "first" and "second" described in the present invention do not represent specific quantities and orders, but are only used to distinguish the names.

[0033] The present embodiment provides an auxiliary flipping device for assembling a vacuum pump, that is, the auxiliary flipping device in the present embodiment is used to assist the vacuum pump in assembling and fixing; wherein, the vacuum pump is assembled from different parts, and the first part assembled in the assembly process is the vacuum pump base, and the remaining parts will be assembled in turn on the basis of the vacuum pump base to complete the assembly of the vacuum pump; and the vacuum pump bases selected for different types of vacuum pumps under different production requirements are different, such as the vacuum pump base of the Roots pump 7 can use the Roots pump cavity 71, and the vacuum pump base of the multi-stage claw type vacuum pump 8 can use the second front partition plate 80.

[0034] See attached Figure 1 As shown, the auxiliary flipping device in this embodiment includes a support seat 1, a clamp assembly 2 arranged on the support seat 1 and used to clamp and fix the vacuum pump base, wherein the clamp assembly 2 is also configured with a driving unit 3 for driving it to perform a fixed-axis rotation action, and the driving unit 3 drives the clamp assembly 2 to perform a fixed-axis rotation action at a preset angle and orientation, which can drive the vacuum pump base to be synchronously flipped and adjusted to a preset angle and orientation along with the fixed-axis rotation action of the clamp assembly 2, that is, the vacuum pump base is firmly connected to the clamp assembly 2 and rotated together with the clamp assembly 2 to an angle that is convenient for the assembler to perform the assembly operation to start the subsequent assembly operation of the remaining components. In this way, the manual flipping operation in the traditional vacuum pump assembly process is replaced, which effectively reduces the occurrence of safety accidents, saves labor costs, saves time and effort, and greatly improves assembly efficiency.

[0035] Specifically, the driving unit 3 in this embodiment includes a reduction motor 31 arranged on the support seat 1, and a transmission shaft 32 connected to the output end of the reduction motor 31 at one end and connected to the clamp assembly 2 at the other end, thereby driving the clamp assembly 2 to achieve synchronous rotation through the forward or reverse rotation of the reduction motor 31 and the transmission action of the transmission shaft 32, and the reduction motor 31 has a self-locking function, which can self-lock after rotating a certain angle, and can effectively avoid slipping while slowing down the rotation speed, thereby improving the safety of use. Secondly, a bearing seat 10 is provided on both sides of the clamp assembly 2, which is rotatably connected to it and fixed on the support seat 1, so as to better fix the bearing and support the flipping action of the clamp assembly 2, so as to avoid the clamp assembly 2 from falling out and further improve the safety of use.

[0036] Furthermore, in order to improve the ease of use of the auxiliary flipping device in this embodiment, a control component 4 is also provided on the support seat 1 for controlling the driving unit 3 to drive the clamp assembly 2 to perform an angular orientation and start-stop action when performing a fixed-axis rotation. The control component 4 is a button seat electrically connected to the reduction motor 31, and a plurality of function buttons (i.e., a control unit) are arranged on the button seat. Each function button can trigger a different rotation action of the reduction motor 31 to drive the clamp assembly 2 to perform a fixed-axis rotation and start-stop action at different angular orientations, such as a first button for driving the clamp assembly 2 to rotate 45° in the forward fixed-axis direction, a second button for driving the clamp assembly 2 to rotate 45° in the reverse fixed-axis direction, a third button for driving the clamp assembly 2 to stop, a fourth button for driving the clamp assembly 2 to rotate 180° in the forward fixed-axis direction, and a fifth button for driving the clamp assembly 2 to rotate 90° in the forward fixed-axis direction; a sixth button for indicating the angular orientation of the clamp assembly 2 at this time; a seventh button for driving the clamp assembly 2 to reset, and the like. It should be noted that the button function here is not unique according to actual production needs; secondly, the forward direction can be clockwise or counterclockwise, and the reverse direction can be counterclockwise or clockwise, and the direction setting is not unique. In addition, a pulley 9 is fixed at the bottom of the support base 1 to facilitate the movement of the support base 1, which is more convenient for the transfer and use of the auxiliary flip device.

[0037] More specifically, the clamp assembly 2 in this embodiment includes a first clamp arm 21 and a second clamp arm 22 arranged opposite to each other, and the opposite end surfaces of the first clamp arm 21 and the second clamp arm 22 are relatively provided with a plurality of connection holes for preset bolts to penetrate and connect; when the bolts are locked, the first clamp arm 21 and the second clamp arm 22 are firmly connected, and when the bolts are loosened, the first clamp arm 21 and the second clamp arm 22 are relatively movably connected, thereby realizing a detachable connection between the first clamp arm 21 and the second clamp arm 22. Among them, the second clamp arm 22 is restricted by the support seat 1 and cannot be disengaged, and the first clamp arm 21 can move freely relative to the support seat 1 when it is not connected and locked with the second clamp arm 22. When assembling, the vacuum pump base is placed in the inner cavity of the second clamp arm 22, and then the first clamp arm 21 is put back and the bolts are locked. At this time, the first clamp arm 21 and the second clamp arm 22 respectively clamp and press the opposite two ends of the vacuum pump base to firmly clamp and fix the vacuum pump base. Furthermore, in order to better fix the vacuum pump base, the first clamp arm 21 and the second clamp arm 22 are provided with a plurality of fixing holes 5 for preset screws 6 to penetrate and connect. When the screws 6 are penetrated and locked, the connection between the first clamp arm 21 and the vacuum pump base, and the second clamp arm 22 and the vacuum pump base can be strengthened, thereby achieving a tightening connection effect. It should be noted here that the modeling specifications of the first clamp arm 21 and the second clamp arm 22 and the opening specifications of the fixing holes 5 should be set according to the type of vacuum pump to be assembled to adapt to different vacuum pump assembly and fixation.
