Description

Technical Field

[0001] The utility model relates to the technical field of mechanical assembly auxiliary equipment, and in particular to an assembly auxiliary device suitable for a dry pump. The utility model aims to provide an assembly auxiliary device capable of flexibly adjusting height and position to improve the efficiency and accuracy of dry pump assembly. Background Art

[0002] Existing dry pump assembly often requires specialized assembly aids due to the precise fit between components. Existing assembly tools are often limited in functionality and are difficult to adapt to the diverse sizes and models of dry pumps. Furthermore, they lack flexibility in height and angle adjustment, hindering assembly efficiency and precision.

[0003] Specifically, the existing assembly method uses screws to secure a fixture to the shaft, tighten the rotor, and then use a gap gauge to measure the gap between the rotor's bottom surface and the baseplate, ensuring that each rotor-base clearance is within the specified range. However, this assembly method has the following drawbacks: 1) Existing screw tightening tools are electric vibrating tools, which have high vibration levels but inconsistent torque. This means that even with the same amount of tightening time, the screws may not be tightened, resulting in inaccurate gap measurements; 2) Each tightening operation with the electric tool wears the fixture, causing iron particles to fall, which affects the gap measurement results.

[0004] Therefore, it is particularly important to develop an assembly auxiliary device that can be flexibly adjusted and easy to operate. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the utility model provides an assembly auxiliary device suitable for a dry pump, comprising a rotating base, a lifting bracket and a top pressure unit, wherein the lifting bracket comprises a fixed sleeve rod fixedly connected to the rotating base, a movable sleeve rod vertically slidably sleeved on the fixed sleeve rod, and a supporting cross bar fixedly connected to the top of the movable sleeve rod and horizontally extended; the top pressure unit is fixedly installed at the end of the supporting cross bar and the top pressure direction of the telescopic end of the top pressure unit is vertically downward.

[0007] Furthermore, the fixed sleeve rod is provided with a fixed through-hole, and the movable sleeve rod is provided with a plurality of movable through-holes arranged vertically, wherein, as the movable sleeve rod slides vertically relative to the fixed sleeve rod, any movable through-hole can be aligned with the fixed through-hole and fixed by a preset pin.

[0008] Furthermore, the assembly auxiliary device suitable for a dry pump is characterized in that the spacing between each of the movable through holes is 40 mm.

[0009] Furthermore, it also includes a jig assembly, wherein the jig assembly includes a jig mold barrel and a pressure-bearing part pivotally connected to the top of the jig mold barrel, and the top pressing unit can align and press the top of the pressure-bearing part.

[0010] Furthermore, the rotating base includes a rotating shaft sleeve and a base body pivotally connected to the rotating shaft sleeve around a vertical axis, wherein a fixing groove for inserting the bottom of the fixing sleeve rod is formed on the top of the base body.

[0011] This utility model employs the above-mentioned solution, achieving the following beneficial effects: through the design of the rotating base, lifting bracket, and top-pressing unit, flexible adjustment and efficient fixation are achieved during the assembly of the dry pump. Furthermore, through the coordination of fixed and movable perforations, the optimization of the spacing between the movable perforations, and the addition of a fixture assembly, the stability and versatility of the device are further improved.

[0016] To facilitate understanding of the present invention, a more comprehensive description of the present invention is provided below with reference to the accompanying drawings. The accompanying drawings illustrate 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. These embodiments are provided solely to provide a more thorough and comprehensive understanding of the disclosure of the present invention.

[0017] See attached Figure 1-3As shown, in this embodiment, an assembly assist device for a dry pump is suitable for the rotor installation process in existing dry pump assembly, precisely controlling the assembly pressure applied each time to maintain consistency. Specifically, the assembly assist device includes a rotating base 1, a lifting bracket 2, and a pressing unit 3. The lifting bracket 2 includes a fixed sleeve 21 fixedly connected to the rotating base 1, a movable sleeve 22 vertically slidingly sleeved on the fixed sleeve 21, and a support crossbar 23 fixedly connected to the top of the movable sleeve 22 and extending horizontally. In this embodiment, the fixed sleeve 21, movable sleeve 22, and support crossbar 23 are all hollow square tube structures.

[0018] In this embodiment, the rotating base 1 comprises a rotating sleeve 11 and a base body 12 pivotally connected to the rotating sleeve 11 about a vertical axis. The rotating sleeve 11 can be fixed to the floor at the operating station, while the base body 12 is correspondingly pivotally connected to the rotating sleeve 11. Furthermore, a fixing groove is formed at the top of the base body 12, into which the bottom of a fixing rod 21 is inserted. Once inserted into the fixing groove, the fixing rod 21 can be secured by screws or welding. Thus, an operator can grasp and rotate the fixing rod 21, thereby driving the synchronous rotation of the base body 12 and adjusting the position of the lifting bracket 2 on the horizontal plane.

[0019] In this embodiment, the lower middle portion of the movable sleeve rod 22 is vertically slidably embedded in the inner cavity of the fixed sleeve rod 21, wherein the shape of the movable sleeve rod 22 matches the shape of the inner cavity of the fixed sleeve rod 21. Secondly, the fixed sleeve rod 21 is provided with a fixed through-hole, and the movable sleeve rod 22 is provided with a plurality of vertically arranged movable through-holes. As the movable sleeve rod 22 slides vertically relative to the fixed sleeve rod 21, any movable through-hole can be aligned with the fixed through-hole and fixed through a preset latch, thereby locking the height of the lifting bracket 2. Based on this, the operator can adjust the height position of the movable sleeve rod 22 relative to the fixed sleeve rod 21 according to the actual height requirements during assembly, and use the latch to fix the aligned movable through-holes and fixed through-holes together.

[0020] In this embodiment, the spacing between each movable perforation is 40 mm. Such a spacing design enables to find a suitable fixed position more quickly when adjusting the height of the lifting bracket 22, while ensuring the accuracy of the adjustment, which just corresponds to the incremental height between each device and the partition, making it easier to adjust the height accurately.

[0021] In this embodiment, one end of the support crossbar 23 is fastened to the top of the movable sleeve rod 22 by welding, screws, or other means. The pressing unit 3 is fixedly mounted to the other end of the support crossbar 23, with the pressing direction of the telescopic end of the pressing unit 3 facing vertically downward. The pressing unit 3 of this embodiment can be a hydraulic or pneumatic telescopic cylinder with its telescopic end facing downward.

[0022] Therefore, the top pressure unit 3 is adjusted to move to an appropriate height position and swing to align with the rotor to be assembled on the dry pump through the rotation function of the rotating base 1 and the telescopic function of the telescopic bracket. Then, the telescopic end of the top pressure unit 3 acts on the rotor to be assembled, thereby applying sufficient pressure to embed the rotor on the pump.

[0023] In this embodiment, a jig assembly 4 is also included, wherein the jig assembly 4 includes a jig mold barrel 41 and a pressure-bearing part 42 pivotally connected to the top of the jig mold barrel 41, and the top pressure unit 3 can be aligned with the top pressure acting on the top of the pressure-bearing part 42, and the jig mold barrel 41 is formed with a mold cavity with a bottom opening for the rotor to be embedded, and the jig mold barrel 41 is pre-mounted on the top of the rotor to be assembled, so that when the top pressure unit 3 is aligned with the top of the pressure-bearing part 42, the top pressure is applied to drive the pressure-bearing part 42, the jig mold barrel 41 and the rotor to move downward synchronously, thereby completing the axial assembly of the rotor; secondly, the pivotal connection between the pressure-bearing part 42 and the jig mold barrel 41 is utilized, so that after the axial assembly of the rotor is completed, the operator can apply force to rotate the jig mold barrel 41 to test whether the rotor can rotate normally and synchronously, and online testing can be achieved without removing the assembly auxiliary device, thereby effectively improving the assembly efficiency.

[0024] In summary, the present invention, an assembly assist device for a dry pump, through the design of a rotating base 1, a lifting bracket 2, and a pressing unit 3, enables flexible adjustment and efficient fixation during dry pump assembly. Furthermore, the coordination of fixed and movable perforations, the optimization of the spacing between the movable perforations, and the addition of a fixture assembly 4 further enhance the device's stability and versatility.

[0025] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any person skilled in the art who, without departing from the scope of the present invention, utilizes the above-disclosed technical content to make further possible variations, modifications, or alterations to the present invention's technical solution shall constitute equivalent embodiments of the present invention. Therefore, any equivalent and equivalent variations made in accordance with the principles of the present invention, without departing from the scope of the present invention's technical solution, shall be encompassed within the scope of protection of the present invention.
