Description

Technical Field

[0001] This utility model relates to the technical field of static balance testing equipment, specifically to a static balance testing fixture for a rotating workpiece. Background Technology

[0002] Mining machinery is generally large in size, especially some models of crushers. Due to their large size, if there is a large deviation in the assembly of the hammer body during operation, the crusher will vibrate violently due to inertia and unbalanced centrifugal force. Because of their large size, this will accelerate the wear of bearings, frames and other components, shorten the service life of the equipment, and may even cause safety accidents. Therefore, it is necessary to adjust the static balance of large rotating parts such as the hammer body.

[0003] In the prior art, there is a patent document with publication number CN209342289U entitled "Rapid Static Balancing Counterweight Fixture for Large Rotating Workpieces." This document describes a device that uses a hydraulic system to control the distance between a vertical plate and a second positioning plate, thereby adjusting the position, by setting up a hydraulic oil tank and a hydraulic pump. However, because this device uses a hydraulic system to adjust the spacing, it requires laying a large number of oil lines, making installation complex and costly. Furthermore, the rotating wheel of a large crusher rotates, and some models have a large diameter range. Using the aforementioned device for balancing adjustment can easily lead to motion interference. To meet market demands, different crusher models and sizes are required depending on the application scenario, making the aforementioned device difficult to meet testing requirements. Utility Model Content

[0004] To overcome the aforementioned shortcomings, the purpose of this utility model is to provide a static balancing test fixture for rotating workpieces, which features an adjustable distance between a first support base and a second support base, simplifying installation and meeting the testing requirements of various equipment.

[0005] To achieve the above objectives, this utility model provides a static balancing test fixture for a rotating workpiece, comprising a base, a first support seat, and a second support seat; the base is provided with a sliding groove, and the bottom of both the first and second support seats are respectively provided with T-bolts corresponding to the sliding groove; the top of the first and second support seats are respectively provided with a rotary support seat, and the rotary support seat is respectively provided with a rotary wheel; the first support seat is also provided with a width adjustment mechanism; the width adjustment mechanism includes: a lead screw support seat, an adjusting lead screw, and a lead screw nut, the lead screw support seat is fixedly connected to the base, the lead screw nut is fixedly connected to the first support seat, and the adjusting lead screw passes through the middle of the lead screw nut and is rotatably mounted on the lead screw support seat.

[0006] Preferably, the rotary support base and the first support base are provided with a first guide key.

[0007] Preferably, a second guide key is provided between the first support and the base, and between the second support and the base.

[0008] Preferably, the first support base and the second support base are each provided with a pair of lifting lugs on both sides.

[0009] The beneficial technical effects achieved by this utility model after adopting the above technical solution are as follows:

[0010] 1. Due to the installation of a slide groove, and the installation of a first support seat and a second support seat within the slide groove, the first support seat is also equipped with a width adjustment mechanism. The width adjustment mechanism is used to adjust the position of the first support seat. The adjustment method adopts the cooperation of an adjusting screw and an adjusting nut. After the adjustment is completed, it is fixed with a T-bolt. In the above process, the distance between the first support seat and the second support seat is changed. It is suitable for static balance testing of various types of rotating workpieces. The operation is extremely simple. The pure mechanical connection can ensure the rigidity of the equipment during testing.

[0011] 2. The adjustment screw and adjusting nut are designed to provide sufficient precision to meet the position adjustment requirements of large rotating parts. Moreover, the height can be set relatively low, eliminating any interference in the middle. Therefore, it is particularly suitable for heavy-duty or large-diameter rotating workpieces. Thus, it can be used not only for testing the static balance of large crusher rotating parts, but also for testing the static balance of large pulleys and other rotating parts, expanding the scope of application of the equipment.

[0012] 3. The slewing support base and the first support base are provided with a first guide key. The first support base and the base and the second support base and the base are respectively provided with a second guide key. In addition to the positioning function during initial installation, the first guide key and the second guide key also have a certain guiding function during the width adjustment process to ensure the accuracy of the movement position.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0022] See Figures 1-4 This utility model provides a static balance test fixture for rotating workpieces, including a base 1, a first support 2, and a second support 2; the base 1 can be a foundation or a support 2 for other heavy equipment.

[0023] The base 1 is provided with a sliding groove 11. The bottoms of the first support seat 2 and the second support seat are each provided with T-bolts 12 corresponding to the sliding groove 11. The tops of the first support seat 2 and the second support seat are each provided with a rotating support seat 21, and each rotating support seat 21 is provided with a rotating wheel 22. The sliding groove 11 is used for connection and guidance. The T-bolts 12 slide within the sliding groove 11. When moved to a designated position, they are connected and fixed with a nut to the T-bolts 12. The first support seat 2 is also provided with a width adjustment mechanism 3. The width adjustment mechanism 3 includes: a screw support seat 31, an adjusting screw 32, and a screw nut 33. The screw support seat 31 is fixedly connected to the base 1, the screw nut 33 is fixedly connected to the first support seat 2, and the adjusting screw 32 penetrates the middle of the screw nut 33 and is rotatably mounted on the screw support seat 31. Figure 1 Taking the crusher's rotating body, shown by the double-dotted line, as an example, the width of the crusher's rotating body is generally measured first. Then, the position is changed by adjusting the lead screw 32 and lead screw nut 33, while the second support seat is generally fixed. After the position is moved, the crusher's rotating body is placed. Once placed, it generally cannot be moved again. Both sides of the crusher's rotating body are supported by rotating wheels 22, and the bottom of the rotating wheels 22 is supported by large bearings to achieve static balance testing of the crusher's rotating body. Since the moving distance of the first support seat 2 is generally not very large, it is generally not necessary to use auxiliary equipment such as bearings and rollers. If the moving span is significantly larger, roller supports are generally installed in the chute 11, or a slide rail is directly installed. This is more expensive, but it can ensure that the adjusting lead screw 32 is almost not subjected to vertical pressure, avoiding damage to the equipment.

[0024] The rotary support 21 and the first support 2 of this utility model are provided with a first guide key 23. The first guide key 23 is used for initial positioning to ensure the accuracy of the installation position. The second guide key 24 is located between the second support and the base 1, and in addition to being used for initial positioning, it is also used to ensure the accuracy of the movement position during adjustment. Figure 4 This is another application of the present invention, used for testing the static balance of large pulleys. If batch testing is being conducted and the positions are completely identical, the width adjustment mechanism 3 can be directly removed after adjustment.

[0025] The first support base 2 and the second support base of this utility model are each provided with a pair of lifting lugs 25 on both sides. The two lifting lugs 25 are used to cooperate with lifting machinery to realize the movement of the equipment.

[0026] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
