[0002] The program controller vibration clamp ensures stable and normal operation of the program controller in a vibration environment by stably connecting and fixing the program controller. However, some program controller vibration clamps use ordinary bolts for threaded connection when connecting the program controller fixing block for fixing the program controller. However, the traditional bolt anti-loosening form is to install an elastic washer to ensure that the nut is in a compressed state, thereby generating a friction torque under pressure to achieve the purpose of nut anti-loosening. This loosening structure does not have an anti-loosening function and is inconvenient to install, which cannot meet the use requirements. CONTENT OF THE UTILITY MODEL

One side of the inclined support plate is connected to each vertical support plate, and the other side is connected to the program controller fixing block through a plurality of self-locking bolt structures. The program controller fixing block is used to connect the program controller.
[0006] In some optional embodiments, the self-locking bolt structure comprises a locking bolt passing through and connected to the program controller fixing block through an external thread, at least one self-locking pin, and a self-locking nut sleeve provided on the locking bolt through an internal thread. The self-locking nut sleeve passes through and is connected to the inclined support plate through an external thread. The outer wall of the self-locking nut sleeve is provided with a self-locking groove corresponding to the self-locking pin. The self-locking groove extends along the axial direction of the self-locking nut sleeve. One end of the self-locking pin is clamped in the corresponding self-locking groove, and the other end is inserted into the program controller fixing block.
[0007] In some optional embodiments, the end of the self-locking nut sleeve away from the program controller fixing block is provided with a hollow circular truncated cone-shaped shrink sleeve. The outer diameter of the shrink sleeve gradually decreases away from the program controller fixing block.
[0008] In some alternative embodiments, the self-locking bolt structure further comprises a pressing screw sleeve sleeved on the locking bolt away from the fixed block of the programmer, and an end surface of the pressing screw sleeve abuts against a surface of the oblique support plate away from the fixed block of the programmer.
[0009] In some alternative embodiments, the pressing screw sleeve and the oblique support plate are connected by a plurality of connecting bolts.

The bottom of the vertical support plate 210 is connected to the top of the base 100, and the bottom of the oblique support plate 220 is connected to the top of the base 100. One side of the oblique support plate 220 is connected to the two vertical support plates 210, and the other side is connected to the programmer fixing block 300 through six self-locking bolt structures. The programmer fixing block 300 is used to connect the programmer.
[0034] The self-locking bolt structure comprises a locking bolt 310 passing through and connected to the programmer fixing block 300 through external threads, two self-locking pins 320, and a self-locking nut 330 sleeved on the locking bolt 310 through internal threads. The programmer fixing block 300 is provided with a first threaded hole 390 connected to each locking bolt 310. The self-locking nut 330 passes through and is connected to the oblique support plate 220 through external threads. The oblique support plate 220 is provided with a second threaded hole 400 through which each locking bolt 310 passes and is connected to the corresponding self-locking nut 330. The first threaded hole 390 is coaxially communicated with the corresponding second threaded hole 400. The end of the self-locking nut 330 away from the programmer fixing block 300 is provided with a hollow circular truncated cone-shaped shrink sleeve 340. The outer diameter of the shrink sleeve 340 gradually decreases away from the programmer fixing block 300. The end face of the end of the self-locking nut 330 away from the shrink sleeve 340 is recessed to form a positioning groove 380. The outer wall of the self-locking nut 330 is provided with two self-locking grooves 350 corresponding to the self-locking pins 320. The self-locking grooves 350 extend along the axial direction of the self-locking nut 330. One end of the self-locking pin 320 is clamped in the corresponding self-locking groove 350, and the other end is inserted into the programmer fixing block 300. The programmer fixing block 300 is provided with a fixing groove 410 for clamping the self-locking pin 320.
[0035] The vibration fixture of the program controller provided by the embodiment of the application can support and connect the program controller fixing block 300 supporting and connecting the program controller through the connection of the fixture main body 200 on the base 100, and the fixture main body 200 is composed of two vertically arranged vertical support plates 210 and a diagonal support plate 220 connected with the two vertical support plates 210, the other side of the diagonal support plate 220 is connected with the program controller fixing block 300 through six self-locking bolt structures, the program controller fixing block 300 can be quickly, efficiently and stably fixed to the diagonal support plate 220 by using the self-locking bolt structure, and the base 100 and the vertical support plate 210 can stably support the program controller fixing block 300 and the program controller, so that the long-time stable operation of the program controller is ensured; the self-locking bolt structure is connected with the program controller fixing block 300 through the first threaded hole 390 on the locking bolt 310 by screwing, and then the locking bolt 310 is inserted into the second threaded hole 400 on the diagonal support plate 220, the self-locking sleeve 330 is sleeved on the locking bolt 310 through the internal thread and connected with the second threaded hole 400 through the external thread, then the two self-locking pins 320 are clamped into the self-locking grooves 350 on the outer wall of the self-locking sleeve 330 by using the press, and further, one end of the self-locking pin 320 is clamped into the fixing groove 410 on the program controller fixing block 300, so that the self-locking pin 320 extrudes the self-locking groove 350 of the self-locking sleeve 330 to make the self-locking sleeve 330 expand and stably connect with the second threaded hole 400 to play a self-locking function, and the self-locking pin 320 inserted into the fixing groove 410 on the program controller fixing block 300 after passing through the self-locking groove 350 also plays a locking function, so that the stable connection of the locking bolt 310, the self-locking sleeve 330, the program controller fixing block 300 and the diagonal support plate 220 is ensured to prevent loosening under long-time vibration, and the program controller fixing block 300 and the diagonal support plate 220 are stably connected by using the nut self-locking structure.
[0036] The end of the self-locking sleeve 330 away from the program controller fixing block 300 is provided with a hollow circular truncated cone-shaped contraction sleeve 340, the outer diameter of the contraction sleeve 340 gradually decreases away from the program controller fixing block 300, so that when the self-locking sleeve 330 is sleeved on the locking bolt 310 through the thread, the locking bolt 310 is pressed outward against the contraction sleeve 340, causing the contraction sleeve 340 to expand and generate stress to play a loosening prevention purpose. The end face of the self-locking sleeve 330 away from the contraction sleeve 340 is recessed to form a positioning groove 380, which can facilitate the rotation of the self-locking sleeve 330 and the threaded connection with the second threaded hole 400 by the positioning groove 380.
[0037] In other optional embodiments, the diagonal support plate 220 can also be connected with the program controller fixing block 300 through two, three, four, five or more than six self-locking bolt structures.

[0039] In other optional embodiments, the fixing groove 410 can also be arc-shaped or ring-shaped extending circumferentially along the self-locking pin 320, so as to facilitate the self-locking pin 320 to be clamped in when the fixing groove 410 is aligned with the self-locking groove 350 by the self-locking sleeve 330 being screwed on the locking bolt 310.
