Description
Technical Field
[0001] This invention relates to the field of bolt technology, and in particular to a device for testing the tensile strength of bolt structures. Background Technology
[0002] Bolts are a common type of fastener, mainly used to connect and fix two or more components. They achieve their fastening function by engaging with a nut or a pre-machined internal threaded hole, utilizing the friction between the threads and axial pressure.
[0003] The bolt structure tensile strength testing device is a device used to measure and evaluate the mechanical properties of bolts under tensile force.
[0004] The existing bolt structure tensile strength testing device has the following shortcomings: During the use of bolts, tensile strength testing is required. However, in the current technology, the fixed seat and the movable seat are usually designed as a single unit, which cannot be separated. This makes it difficult to quickly place the bolt to be tested into the placement slot, resulting in low overall testing efficiency. Summary of the Invention

Through the above components, the user can quickly place the bolt into the interior of the first and second placement plates, and through the cooperation of the fixing mechanism, the bolt can be stably positioned within both plates, ensuring that subsequent operations can proceed normally.
[0007] Preferably, the inner walls of both the first and second placement plates are fixedly connected with second guide rods, and the outer wall of the second guide rod is slidably connected to the inner wall of the second fixing member. By setting the second guide rod, the stability of the second fixing member when moving up and down can be improved so that it can properly contact the outer wall of the bolt.
[0008] Preferably, a PLC controller is fixedly installed on one side of the top of the base plate, and the shaft end of the second electric push rod is fixedly connected to the outer wall of the second placement plate. The PLC controller allows users to control and use the components through the control panel on it.
[0009] Preferably, the inner wall of the second placement plate is provided with a circular hole, and the inner wall of the circular hole is slidably connected to the outer wall of the first guide rod. Through the circular hole, the second placement plate can slide normally on the first guide rod, thereby improving the stability of the second placement plate when moving back and forth.
[0010] Preferably, each of the base plates is fixedly connected to a support leg, and each support leg is fixedly installed with a third electric push rod. The support legs and rubber pads improve the overall stability during use.
[0011] Preferably, each of the third electric push rods has a fixedly mounted caster wheel at its shaft end, and each of the support legs has a fixedly connected rubber pad at its bottom. With the third electric push rod and caster wheel, the entire assembly can be lifted up and moved to any location via the caster wheel, thereby improving the overall flexibility.
[0012] Preferably, the component to be tested includes a bolt body, and a nut is threadedly connected to one side of the outer wall of the bolt body. By using the nut, the bolt body can be stably positioned inside the first fixing member and the second fixing member.
[0013] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, the first and second placement plates facilitate the user to place the bolt inside, changing the previous method of setting it as a whole. Then, through the cooperation of the first electric push rod, guide rod, first fixing member, second fixing member and nut, it can be ensured that the bolt body is stably placed inside the first and second placement plates, which indirectly ensures the normal progress of subsequent operations.
[0014] 2. In this invention, the first guide rod can improve the stability of the second placement plate when it moves back and forth, so that the testing operation can be carried out normally. The moving mechanism facilitates the user to move the whole thing and improves the overall flexibility. Attached Figure Description

[0019] Please see Figures 1-5 This invention provides a technical solution: a bolt structure tensile strength testing device, including a placement mechanism 1, with a test component 2 slidably connected inside the placement mechanism 1; the placement mechanism 1 includes a base plate 101, a first placement plate 102 fixedly connected to one side of the top of the base plate 101, a second placement plate 104 slidably connected to the inner wall of the base plate 101, a set of first fixing members 112 fixedly connected to the inner walls of the first placement plate 102 and the second placement plate 104, a first electric push rod 115 fixedly installed on the inner walls of the first placement plate 102 and the second placement plate 104, a set of second fixing members 113 fixedly connected to the shaft end of the first electric push rod 115, a second electric push rod 105 fixedly installed on the top of the base plate 101, and a first guide rod 103 fixedly connected to the inner walls of the base plate 101. Through the above components, it is convenient for the user to quickly put the bolt into the first placement plate 102 and the second placement plate 104, and through the cooperation of the fixing mechanism, it can be ensured that the bolt is stably placed inside both, ensuring that subsequent operations can be carried out normally.
[0020] like Figure 1 and Figure 3 As shown, the inner walls of the first placement plate 102 and the second placement plate 104 are both fixedly connected with the second guide rod 114. The outer wall of the second guide rod 114 is slidably connected to the inner wall of the second fixing member 113. By setting the second guide rod 114, the stability of the second fixing member 113 when moving up and down can be improved so that it can normally contact the outer wall of the bolt.
[0021] like Figure 1 and Figure 3 As shown, a PLC controller 107 is fixedly installed on one side of the top of the base plate 101. The shaft end of the second electric push rod 105 is fixedly connected to the outer wall of the second placement plate 104. The PLC controller 107 allows users to control and use the components through the control panel on it.
[0022] like Figure 5 As shown, the inner wall of the second placement plate 104 is provided with a circular hole 111. The inner wall of the circular hole 111 is slidably connected to the inner wall of the first guide rod 103. Through the circular hole 111, the second placement plate 104 can slide normally on the first guide rod 103, so as to improve the stability of the second placement plate 104 when moving back and forth.
[0023] like Figure 1 and Figure 3 As shown, the bottom of the base plate 101 is fixedly connected with support legs 106, and the third electric push rod 110 is fixedly installed inside the support legs 106. The support legs 106 and the rubber pads 108 are designed to improve the overall stability when in use.
[0024] like Figure 4 As shown, each shaft end of the third electric push rod 110 is fixedly equipped with a movable wheel 109, and the bottom of each support leg 106 is fixedly connected with a rubber pad 108. Through the third electric push rod 110 and the movable wheel 109, the whole can be lifted up and moved to any location by the movable wheel 109, which can improve the flexibility of the whole.
[0025] like Figure 1 and Figure 2 As shown, the component under test 2 includes a bolt body 201, and a nut 202 is threadedly connected to one side of the outer wall of the bolt body 201. By setting the nut 202, the bolt body 201 can be stably positioned inside the first fixing member 112 and the second fixing member 113.
[0026] The usage and working principle of this device are as follows: First, the entire device can be moved to a designated location using the casters 109. Then, the third electric push rod 110 is retracted via the control panel on the PLC controller 107, causing the casters 109 to move into the support leg 106, thus bringing the rubber pad 108 into contact with the ground. The user can then insert the bolt body 201 into the first placement plate 102 and the second placement plate 104, positioning it between the first fixing member 112 and the second fixing member 113. After insertion, the first electric push rod 115 is activated, causing it to move downwards towards the second fixing member 113. The bolt body 201 is moved down to contact the outer wall of the bolt body 201, completing the initial fixation. Then, the user screws the nut 202 into one side of the bolt body 201 and screws it until it contacts the surface of the first fixing member 112 and the second fixing member 113 on the first placement plate 102 to complete the secondary fixation of the bolt body 201. Then, the second electric push rod 105 is activated so that the second placement plate 104 can move horizontally and slide on the first guide rod 103. When sliding, the bolt body 201 to be tested is stretched, thereby performing tensile strength testing on the bolt body 201.
[0027] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
