[0001] The present disclosure relates to the field of bearing installation, and more particularly, to a mounting fixture. Background Art

[0002] During the overhaul of high-voltage motors, it is necessary to replace the rolling bearings of the motors. Since the clearance between the bearing housing and the bearing is extremely small, the current installation method is for workers to manually hammer or use a copper bar to knock the outer sleeve of the bearing into the bearing housing. However, this method is prone to accidentally damaging the bearing, which affects the work efficiency. Summary of the Utility Model

[0003] The purpose of the present disclosure is to provide a mounting fixture that can insert one workpiece into another by means of clamping and extrusion, thereby at least partially solving the above technical problems.

[0004] To achieve the above purpose, the present disclosure provides a mounting fixture, including: a first clamping member including a first fitting surface for fitting with at least a part of a first workpiece; a second clamping member including a second fitting surface for fitting with at least a part of a second workpiece; and a connecting member for connecting the first clamping member and the second clamping member so that a clamping space for accommodating the first workpiece and the second workpiece is formed between the first clamping member and the second clamping member; the first clamping member and the second clamping member can approach or move away from each other through the connecting member to squeeze and insert one of the first workpiece and the second workpiece into the other.

Detailed implementation manners

[0021] The following will describe in detail the detailed implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the detailed implementation manners described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0022] The terms "first", "second", etc. used in the present disclosure are used to distinguish one element from another, and do not have sequentiality and importance. In addition, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure, and should not be construed as a limitation to the present disclosure.

[0023] The installation fixture in the exemplary embodiment of the present disclosure will be described below with reference to the accompanying drawings.

[0024] As Figure 1 and Figure 2As shown, the present disclosure provides a mounting fixture, including a first clamping member 1, a second clamping member 2, and a connecting member 3. Among them, the first clamping member 1 includes a first fitting surface 101 for fitting with at least a part of a first workpiece; the second clamping member 2 includes a second fitting surface 201 for fitting with at least a part of a second workpiece; the connecting member 3 is used to connect the first clamping member 1 and the second clamping member 2, so that a clamping space 4 for accommodating the first workpiece and the second workpiece is formed between the first clamping member 1 and the second clamping member 2; the first clamping member 1 and the second clamping member 2 can approach or move away from each other through the connecting member 3, so as to squeeze and fit one of the first workpiece and the second workpiece into the other. When it is necessary to assemble the first workpiece and the second workpiece together, for example, when installing a bearing outer ring into a bearing housing, the staff can first adjust the distance between the first clamping member 1 and the second clamping member 2, that is, the size of the clamping space 4, according to the sizes of the bearing and the bearing housing, so as to ensure that the bearing outer ring and the bearing housing can be simultaneously installed into the clamping space 4. Subsequently, the bearing outer ring can be fitted with one of the first fitting surface 101 and the second fitting surface 201, and the bearing housing can be fitted with the other. The staff can make the first clamping member 1 and the second clamping member 2 approach each other by adjusting the connecting member 3, and the bearing outer ring and the bearing housing will be squeezed against each other under the action of the first fitting surface 101 and the second fitting surface 201 until the bearing outer ring is sleeved on the bearing housing. Compared with the prior art method of using tools such as hammers or copper bars to knock and install, the present disclosure can increase the force-bearing area on the bearing outer ring and the bearing housing through the first fitting surface 101 and the second fitting surface 201, making the force on the bearing outer ring and the bearing housing relatively even. On the one hand, this can ensure the stability during the assembly of the two, and on the other hand, it can also avoid the situation of accidentally damaging the workpiece, improving the assembly efficiency.

[0025] In some embodiments of the present disclosure, as Figure 1 and Figure 2 shown, the first clamping member 1 is threadedly connected to the connecting member 3, and the second clamping member 2 is movably arranged on the connecting member 3 to approach or move away from the first clamping member 1. That is, the first clamping member 1 and the connecting member 3 remain in a relatively fixed state, while the second clamping member 2 can reciprocally move on the connecting member 3 to change the size of the clamping space 4, facilitating the assembly of workpieces of different sizes and models by the present disclosure.

[0026] Among them, as Figure 1 and Figure 2As shown, the connecting member 3 may include a connecting portion 31 and a limiting portion 32 threadedly connected to the connecting portion 31. The first clamping member 1 is threadedly connected to the connecting portion 31, and the limiting portion 32 is disposed between one side of the second clamping member 2 facing away from the first clamping member 1 and the end of the connecting portion 31. When assembling the first workpiece and the second workpiece, the first clamping member 1 can be connected to the connecting portion 31 by threaded connection. The second clamping member 2 is in a free state and its position on the connecting portion 31 can be adjusted according to the sizes of the first workpiece and the second workpiece. When it is necessary for the first clamping member 1 and the second clamping member 2 to approach each other and squeeze the first workpiece and the second workpiece, the operator can rotate the limiting portion 32 to make the limiting portion 32 abut against the second clamping member 2 and gradually move towards the first clamping member 1. Based on this, the limiting portion 32 can drive the second clamping member 2 to move towards the first clamping member 1 so that the first clamping member 1 and the second clamping member 2 approach each other.

[0027] Specifically, the connecting portion 31 can be configured as a screw rod, and the limiting portion 32 can be constructed as a nut. That is, the first clamping member 1 is threadedly connected to the screw rod, the nut is threadedly connected to the screw rod, and the nut can change its position on the screw rod by forward and reverse rotation, so that the second clamping member 2 can approach or move away from the first clamping member 1.

[0028] In some embodiments, as Figure 1 and Figure 2 shown, the first clamping member 1 can be configured as a first channel steel, and the second clamping member 2 can be configured as a second channel steel; the first channel steel includes a threaded hole 5 for threaded connection with the connecting portion 31, and the second channel steel includes a through hole 6 for the connecting portion 31 to pass through. Using channel steel as the first clamping member 1 and the second clamping member 2 can ensure the strength of the first clamping member 1 and the second clamping member 2. The first channel steel can be threadedly connected to the screw rod through the threaded hole 5, and the diameter of the through hole 6 on the second channel steel can be larger than the diameter of the screw rod. Thus, the second channel steel can reciprocate on the screw rod to adjust its position on the screw rod and change the size of the clamping space 4.

[0029] In some embodiments of the present disclosure, as Figure 1 and Figure 2 shown, the connecting member 3 can be disposed at the center of the first clamping member 1 and the second clamping member 2. This can make the first clamping member 1 and the second clamping member 2 move more stably through the connecting member 3. In addition, taking the connecting member 3 as a dividing point, the clamping space 4 can be divided into two parts, so that two groups of workpieces can be assembled simultaneously, improving the work efficiency.

[0030] In some embodiments, as Figure 1 and Figure 2As shown, the installation fixture may further include a guiding and limiting member 7. The guiding and limiting member 7 connects the first clamping member 1 and the second clamping member 2 and is spaced apart from the connecting member 3. The guiding and limiting member 7 can ensure the stability of the first clamping member 1 and / or the second clamping member 2 when moving on the connecting member 3, and avoid the situation of rotation on the connecting member 3. In addition, the guiding and limiting member 7 can also ensure that the first clamping member 1 and the second clamping member 2 are parallel to each other, avoiding the situation where the first workpiece and the second workpiece cannot be assembled due to non-parallelism of the two.

[0031] Specifically, the first clamping member 1 may include a first limiting hole 102, and the second clamping member 2 may include a second limiting hole 202. The guiding and limiting member 7 can abut against the first clamping member 1 through the first limiting hole 102 and can pass through the second clamping member 2 through the second limiting hole 202. In this way, when the first clamping member 1 remains fixed and the second clamping member 2 moves on the connecting member 3, the guiding and limiting member 7 passing through the second clamping member 2 will prevent the second clamping member 2 from rotating, thereby preventing the situation that affects the assembly efficiency.

[0032] Among them, the first limiting hole 102 and the second limiting hole 202 may be configured as strip-shaped holes. To ensure the connection effect between the guiding and limiting member 7 and the two while reducing the weights of the first clamping member 1 and the second clamping member 2.

[0033] In some embodiments of the present disclosure, as Figure 1 and Figure 2 shown, the guiding and limiting member 7 may be configured into two, and the two guiding and limiting members 7 are respectively arranged on both sides of the connecting member 3. This can further ensure the stability and parallelism of the first clamping member 1 and the second clamping member 2 when moving.

[0034] In summary, the present disclosure exemplarily shows the working process of the installation fixture for assembling the bearing outer ring and the bearing seat.

[0035] The staff can first adjust the distance between the first clamping member 1 and the second clamping member 2 according to the size of the bearing sleeve and the bearing seat, and then put the bearing sleeve and the bearing seat into the clamping space 4. At this time, one of the bearing sleeve and the bearing seat can fit with the first fitting surface 101 of the first clamping member 1, and the other can fit with the second fitting surface 201 of the second clamping member 2. Then, the nut is rotated so that the nut is against the side of the second clamping member 2 on the screw that is away from the first clamping member 1 and continues to move toward the side close to the first clamping member 1. As a result, the second clamping member 2 will gradually move toward the first clamping member 1. When one side of the holder 1 moves, the bearing sleeve and the bearing seat will be squeezed against each other by the first fitting surface 101 and the second fitting surface 201 until the bearing sleeve is mounted in the bearing seat. Compared with the installation method in the related art which requires the use of tools such as a hammer or a copper rod, the present invention can increase the force-bearing area of ​​the bearing sleeve and the bearing seat through the first fitting surface 101 and the second fitting surface 201, so that the force on the bearing sleeve and the bearing seat is relatively even. This can ensure the stability of the two during assembly on the one hand, and avoid accidental damage to the workpiece on the other hand, thereby improving assembly efficiency.

[0036] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0037] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0038] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
