Description

Technical Field

[0001] The utility model belongs to the technical field of external thread bearing installation, in particular to an external thread bearing installation tool. Background Art

[0002] An externally threaded bearing is a bearing that includes a bearing and a connecting screw connected to the bearing and the bearing support seat. Specifically, during operation, the externally threaded bearing is often installed on the bearing support seat. After installation, the externally threaded bearing needs to be kept installed on the bearing in an extremely stable manner.

[0003] At present, during the installation process, when the external threaded bearing is installed on the bearing support seat, it is necessary to fasten the screw to the corresponding threaded through hole on the bearing support seat. The specific method is that the operator uses a tool to fasten the bearing bracket and the bearing with the connecting screw. However, during the fastening process of the bearing, especially the small-sized bearing, it is difficult to maintain the stability of the bearing. During the fastening process, the bearing is easy to rotate, which makes it easy to "lack strength" during installation, so the assembly is more cumbersome.

[0004] Therefore, in order to assemble the bearing and the bearing support seat in a fast and efficient manner, the bearing is often positioned by touch pressure. A common method is to press the bearing with your hand, and then tighten the connecting screw to the bearing support seat and the bearing. Although this method can install the bearing without obstruction, once the number of installations is large during the actual operation, this method is obviously not suitable for batch installation. At the same time, during the installation process, the strength of the hand is difficult to control. When the strength is too large, it is easy to cause the gasket on the bearing to be pressed and deformed.

[0005] Secondly, the defect of installing in this way is that during the installation process, the tool for tightening the screw rod is easy to hit the hand. Specifically, the hand is pressed on the small-sized bearing, and the gap of the exposed installation position is small. During the process of tightening the screw rod, as the screw rod connects the bearing and the bearing support seat, the height of the screw rod decreases, and the tool such as the electric screwdriver is lowered, which can easily touch and press the operator's hand. In addition, during the installation of small-sized bearings, the hand pressing surface is not large, and the pressing is mostly on one side. Therefore, if the force is not well controlled, the bearing is easy to tilt, so it is very troublesome to install. Utility Model Content

[0006] Based on the above background, the purpose of the utility model is to provide an external threaded bearing installation tool.

[0007] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0012] A strip-shaped mounting through hole is provided on the U-shaped touch-pressure rod, and the U-shaped touch-pressure rod is assembled at the top position of the tooling seat through an elastic lifting member; during the installation of the bearing, the touch-pressure parts at both ends of the U-shaped touch-pressure rod touch the top of the bearing, and the mounting bolts pass through the strip-shaped mounting through hole to fasten the bearing to the bearing support seat.

[0013] Preferably, the spring mechanism comprises two spring cavities opened on the tooling seat, wherein springs are fixedly connected in the spring cavities respectively, and the springs are fixedly connected to push rods slidably connected to the spring cavities;

[0014] During installation, the two threaded mounting holes on the bearing support are aligned with the top rod protruding from the spring cavity.

[0015] Preferably, a detection slot is provided on the top of the tooling seat;

[0016] The size of the detection tank body corresponds to the size of the bearing. After installation, the bearing is placed in the detection tank body, and the detection tank body is used as a reference.

[0017] Preferably, the elastic lifting member comprises a vertical screw rod slidably connected to the U-shaped contact pressure rod, a telescopic spring is sleeved on the vertical screw rod, and a pressing nut for pressing the U-shaped contact pressure rod is threadedly connected to the upper end of the vertical screw rod.

[0018] Preferably, the bottom of the telescopic spring is fixedly connected to the top of the tooling seat, the bottom of the U-shaped touch-pressure rod is fixedly connected to a spring seat, and the top of the telescopic spring is supported on the bottom of the spring seat.

[0019] Preferably, the U-shaped contact pressure rod comprises contact pressure parts arranged in parallel at two ends, a bent connection part is integrally formed between the contact pressure parts, and the elastic lifting member is assembled and connected to the bent connection part.

[0020] Preferably, the U-shaped contact pressure rod comprises contact pressure portions arranged in parallel at two ends;

[0021] The contact and pressure portion and the bent connection portion are respectively assembled and connected via spacing adjustment pieces.

[0022] Preferably, the spacing adjustment member comprises a long sliding screw fixedly connected to the bent connection portion;

[0023] The long sliding screw is slidably connected to the contact and pressure portion, and a pair of adjusting nuts positioned on both sides of the strip-shaped mounting through hole are threadedly connected to the long sliding screw;

[0024] The length of the long sliding screw is smaller than the length of the strip-shaped mounting through hole.

[0025] Preferably, the side walls on both sides of the contact and pressure portion are detachably connected with extended pressure plates;

[0028] The utility model has the following beneficial effects:

[0029] 1. By setting a spring mechanism on the tooling seat, during the installation process, under the threaded connection force, the elasticity of the bearing and the bearing support seat decreases, and the spring is compressed during the descent process, thereby achieving a buffer and protecting the bearing.

[0030] 2. Through the U-shaped touch-pressure rod, specifically, through the U-shaped touch-pressure rod elastic lifting member assembled at the top position of the tooling seat, during the working process, the pressing nut is screwed downward until the pressing nut drives the U-shaped touch-pressure rod to descend, and the contact pressure parts at both ends press the bearing, which is convenient for processing. The shape of the above-mentioned U-shaped touch-pressure rod is: the U-shaped touch-pressure rod includes contact pressure parts arranged in parallel at both ends, and a curved connection part is integrally formed between the contact pressure parts, and the elastic lifting member is assembled and connected to the curved connection part.

[0031] After installation, since the top of the telescopic spring is not fixed on the spring seat, the nut is screwed upward. At this time, under the restoring force of the telescopic spring, the U-shaped contact pressure rod is reset and rotated to a position where the contact pressure parts at both ends of the U-shaped contact pressure rod leave the upper part of the bearing.

[0032] 3. The length of the contact and pressure part can be adjusted in advance by loosening the adjustment nut during operation. During the sliding adjustment of the contact and pressure part, the long sliding screw adjusts its length in the strip-shaped installation through hole. Since the length of the long sliding screw is less than the length of the strip-shaped installation through hole, a position for installing the connecting screw can still be reserved. Through adjustment, the contact and pressure part can be adjusted according to the size of the bearing during the installation of the bearing, ensuring that the contact and pressure part can be fully and fully pressed on the top of the bearing.

[0043] Example 1

[0044] like Figure 1-5 As shown, an external thread bearing installation tool comprises a tool seat 1, and a mounting groove 14 for mounting the bearing is provided on the top of the tool seat 1. In order to elastically support the bearing 22 and the installed bearing support seat 21 during the installation process, a buffering effect is played during the installation process to protect the bearing. A spring mechanism 13 is assembled and connected in the above-mentioned mounting groove 14, and the spring mechanism 13 is supported on the bottom of the bearing support seat during the installation process.

[0045] Specifically, the spring mechanism 13 includes two spring cavities opened on the tooling seat 1, and springs 132 are fixedly connected in the spring cavities respectively. The spring 132 is fixedly connected to a push rod 131 slidably connected to the spring cavity (the push rod 131 is T-shaped, adapted to the spring cavity of the corresponding shape, and the push rod 131 is located in the spring cavity in a sliding and limiting manner). One end of the spring 132 is fixedly connected to the inner wall of the spring cavity, and the other end is fixed to the inner end of the push rod 131.

[0046] During the installation process, the two threaded mounting holes on the bearing support seat 21 are aligned with the top rod 131 protruding from the spring cavity. Specifically, two bearings are installed on the bearing support seat 21. Each bearing 22 corresponds to a threaded mounting hole. The threaded mounting holes on the bearing support seat 21 are aligned one by one to the top of the top rod 131. At this time, the top rod 131 is supported at the bottom of the threaded mounting hole (the outer diameter of the top rod 131 is larger than the aperture of the threaded mounting hole).

[0047] A rubber washer is placed at the location of the threaded mounting hole (for buffering). At this time, the bearing 22 and the bearing support seat 21 are fastened by connecting screws. Specifically, the connecting screws fasten the threaded mounting holes of the bearing support seat 21 and then fasten them to the corresponding mounting threaded holes on the bearing (the mounting threaded holes are not drawn on the bearing shown in the figure).

[0048] During the installation process, under the threaded connection force, the elasticity of the bearing 22 and the bearing support seat 21 decreases, and the spring is compressed during the descent, thereby achieving a buffer to protect the bearing 22 (using the deformation of the spring to form a buffer is a conventional application of the inherent property of the spring).

[0049] After installation, in order to detect whether the installed bearing is completely fastened to the bearing support seat 21, a detection slot 11 is opened on the top of the tooling seat 1; the size of the detection slot 11 corresponds to the size of the bearing. After installation, the bearing is placed in the detection slot 11, and the size of the detection slot 11 is used as a reference. When the bearing can fit in the detection slot 11, the bearing is installed properly. Specifically, the middle part of the detection slot is divided into two parts by a height rib plate. During the inspection, a bearing is placed in each half slot.

[0050] Specifically, when the bearing 22 is completely tightened by the connecting screw, at this time, the bearing 22 is facing downward, the bearing support seat 21 is facing upward, and the bearing 22 is inserted into the detection slot. When the bearing 22 is completely inserted into the detection slot (one bearing is placed in each half-slot position), and the bottom of the bearing support seat 21 can be supported on the height rib plate without any gap, the surface bearing is completely fastened to the bearing support seat 21. On the contrary, when there is a height gap between the height rib plate and the bearing support seat 21, it means that the bearing has not been completely fastened to the bearing support seat 21 and needs to be disassembled and re-fastened.

[0051] Example 2

[0052] like Figure 1-5 As shown, in this embodiment, based on the structure of the first embodiment, in order to improve the stability of the bearing during the installation process, the external threaded bearing installation tool further includes a contact pressure locking mechanism 3 for contacting and pressing the bearing during the installation process. Specifically, the contact pressure locking mechanism 3 includes a U-shaped contact pressure rod that contacts and presses the top position of the bearing. The two ends of the U-shaped contact pressure rod each have a contact pressure portion 31, and the contact pressure portion 31 is provided with a strip-shaped installation through hole 311 (during the installation process, the connecting screw passes through the strip-shaped installation through hole 311 to fasten the bearing to the bearing support seat 21).

[0053] The U-shaped touch-pressure rod is assembled at the top of the tooling seat 1 through an elastic lifting member; specifically, the elastic lifting member includes a vertical screw rod 33 slidably connected to the U-shaped touch-pressure rod, a telescopic spring 35 is sleeved on the vertical screw rod 33, and a pressing nut 34 for pressing the U-shaped touch-pressure rod is threadedly connected to the upper end of the vertical screw rod 33. Correspondingly, the bottom of the telescopic spring 35 is fixedly connected to the top of the tooling seat 1, and the bottom of the U-shaped touch-pressure rod is fixedly connected to a spring seat 321, and the top of the telescopic spring 35 is supported on the bottom of the spring seat 321 (the spring seat 321 is slidably connected to the vertical screw rod 33).

[0054] During the working process, the pressing nut 34 is screwed downward until the pressing nut 34 drives the U-shaped contact pressure rod to descend, and the contact pressure parts 31 at both ends press the bearing, which facilitates processing.

[0055] The U-shaped touch-pressure rod has the following shape: the U-shaped touch-pressure rod comprises touch-pressure portions 31 arranged in parallel at two ends, a curved connection portion 32 is integrally formed between the touch-pressure portions 31 , and the elastic lifting member is assembled and connected to the curved connection portion 32 .

[0056] After installation, since the top of the telescopic spring 35 is not fixed on the spring seat 321, the nut 34 is screwed upward. At this time, under the restoring force of the telescopic spring 35, the U-shaped contact pressure rod is reset and rotated to a position where the contact pressure parts 31 at both ends of the U-shaped contact pressure rod leave the upper position of the bearing.

[0057] Example 3

[0058] like Figure 1-5 As shown, this embodiment is a variation of the embodiment 2, the contact and pressure portion 31 and the bent connection portion 32 are connected by a spacing adjustment member (not in an integrated molding manner), specifically, the spacing adjustment member includes a long sliding screw 36 fixedly connected to the bent connection portion 32; the long sliding screw 36 is slidably connected to the contact and pressure portion 31, and a pair of adjustment nuts 361 positioned on both sides of the strip-shaped mounting through hole 311 are threadedly connected to the long sliding screw 36. Specifically, the length of the long sliding screw 36 is less than the length of the strip-shaped mounting through hole 311.

[0059] During operation, after loosening the adjustment nut 361 in advance, the contact and pressure portion 31 is slidably adjusted. During the sliding adjustment process of the contact and pressure portion 31, the long sliding screw 36 is adjusted in length in the strip-shaped installation through hole 311. Since the length of the long sliding screw 36 is shorter than the length of the strip-shaped installation through hole 311, a position for installing the connecting screw can still be reserved.

[0060] Through the adjustment, during the process of installing the bearing, the contact and pressure portion 31 can be adjusted according to the size of the bearing to ensure that the contact and pressure portion 31 can be completely and fully pressed on the top of the bearing.

[0061] Example 4

[0062] like Figure 1-5 As shown, in this embodiment, on the basis of the embodiment 3, the side walls on both sides of the above-mentioned touch and pressure portion 31 are detachably assembled and connected with extended pressing plates 37 (the detachable manner is: a vertically arranged mounting seat 371 is welded on the top of the extended pressing plate 37, and the mounting seat 371 is fastened to the side wall of the touch and pressure portion 31 by a screw). Its shape is wavy, specifically, a plurality of curved touch and pressure portions 31 are integrally formed on the extended pressing plate 37.

[0063] The bottom of the extending pressing plate 37 is flush with the bottom of the contacting and pressing portion 31 .

[0064] During operation, the contact surface with the bearing ground is increased by extending the pressure plate 37, thereby increasing the force of contact pressure to position the bearing and ensuring the stability of the installation.

[0065] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
