[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) The operation of the spring-loaded clamping control device allows the mold to be installed on the device conveniently and quickly, avoiding dislocation, displacement, shaking, etc. of the mold after installation, further improving the installation effect of the device on the mold, and avoiding shaking or instability of the bolts fixed on the mold during detection, thereby further improving the detection effect of the device; and the above installation steps are convenient and quick, and the mold installation operation can be completed by placing the mold in the rectangular box with one hand and pressing it. The loading and unloading process does not require any tools to complete, which reduces the limitations of the device during use, reduces the difficulty and tediousness of loading and unloading the mold by the device, ensures the speed of replacing the mold by the device, ensures the loading and unloading efficiency, and makes it easy to replace the mold by the device, thereby avoiding the detection effect of the device being affected due to the low efficiency of replacing the mold by the device, thereby improving the use effect of the device; When the cam is in a state of being ... (3) After the bolt is fixed, when the control unit sends a signal to open the valve at the ventilation duct, the gas in the air bag continues to flow into the ventilation duct because there is a venting channel, so that the deformed air bag is gradually reset and the gas is ejected through the high-pressure nozzle. The gas acts on the fixed bolt, so that the bolt can be cleaned and impurities or dust adhering to the surface and thread of the bolt can be cleaned to avoid the presence of these impurities affecting the detection result of the device on the bolt, thereby improving the accuracy of the device on the bolt detection, further reducing the work intensity of the staff, reducing the limitations of the device when in use, avoiding the need for the staff to add extra power sources, resulting in an increase in the use cost, and thus improving the use effect of the device; (4) When the mold contacts the fitting square plate in the rectangular box, it moves within the rectangular box and makes the rubber cushion on the fitting square plate contact the mold. This not only increases the friction between the fitting square plate and the mold, but also prevents the mold from being dislocated and displaced. At the same time, the cushioning force brought by the rubber cushion and the guide spring can reduce the impact force on the mold during installation, thereby improving the installation effect and stability of the device on the mold, and avoiding the deviation of the mold installation position affecting the device's detection effect on the bolts, so that the bolts can be used for detection by the device in a suitable position, thereby improving the detection effect of the device. At the same time, when the mold moves to the maximum position in the rectangular box, it indicates that The mold has completed the installation operation. At this time, the side of the fitting square plate away from the rubber buffer pad is in contact with the contact pieces provided on the opposite side of the rectangular box. The signal sent is transmitted to the control unit to remind the staff to pay attention, indicating that the mold has been installed. At the same time, if the mold is dislocated, the fitting square plate is no longer subjected to force, so that the guide spring in the buffer state is reset, and the two contact pieces are no longer in contact, indicating that the mold is dislocated, so that the control unit can receive the message in the first time and notify the staff, avoiding the mold dislocation so that the staff cannot be notified in time, resulting in accurate detection of the bolts fixed on the mold, thereby improving the use effect of the device; (5) The U-shaped slide cylinder drives the auxiliary horizontal plate to move under the action of the auxiliary square column and the auxiliary spring, so that the resistance friction plate on it moves close to the moment horizontal block and contacts it under the action of the driving slide column, so that the resistance friction plate can apply a downward force to the reset moment horizontal block, thereby limiting the moment horizontal block and limiting it to the current position, preventing the U-shaped clamping plate from being unable to continue clamping the mold due to the movement of the moment horizontal block when clamping the mold, thereby increasing the friction force of the moment horizontal block and the moment slide column, allowing the device to further limit the mold, preventing the mold from being dislocated or shaking after installation, which affects the bolt detection process, and reducing the limitations of the device when in use; (6) After the resistance friction plate contacts the torque cross block, when it continues to drive the auxiliary cross plate downward through the U-shaped slide, it moves to the upper limit of the driving slide column, so that the driving spring is in a buffering state, further strengthening the connection between the resistance friction plate and the torque cross block, and improving the installation effect of the device on the mold; at the same time, since the side of the resistance friction plate close to the torque cross block is an inclined surface, if the movement speed of the resistance friction plate is greater than the torque cross block, it means that the torque cross block first contacts the side of the resistance friction plate, so that the torque cross block contacts the inclined surface of the resistance friction plate, thereby exerting an upward force on it, so that the resistance friction plate moves close to the auxiliary cross plate through the driving slide column, so that the driving spring is in a buffering state, so that the bottom surface of the resistance friction plate contacts the top surface of the torque cross block, which also limits the position of the torque cross block, further avoiding its position change, and improving the use effect of the device.

When the mold required for the fixing bolt needs to be installed, the mold is placed in the rectangular box 3 and moved, so that the mold contacts the fitting square plate 9 in the rectangular box 3, so that it moves within the rectangular box 3, and at the same time, the rubber buffer pad 10 on the fitting square plate 9 is in contact with the mold, which not only increases the friction between the fitting square plate 9 and the mold, avoiding dislocation and displacement of the mold, but also reduces the impact force on the mold during installation through the buffering force brought by the rubber buffer pad 10 and the guide spring 14, thereby improving the installation effect and stability of the device on the mold and avoiding deviations in the mold installation position that affect the device. The detection effect on the bolts enables the bolts to be detected by the device in a suitable position, thereby improving the detection effect of the device; at the same time, when the mold moves to the maximum position in the rectangular box 3, it indicates that the mold has completed the installation operation. At this time, the side of the fitting square plate 9 away from the rubber buffer pad 10 is in contact with the contact piece 13 provided on the opposite side of the rectangular box 3, and the signal sent is transmitted to the control unit to remind the staff to pay attention, indicating that the mold has been installed. At the same time, if the mold is dislocated, the fitting square plate 9 is no longer subjected to force, so that the guide spring 14 in the buffer state is reset, so that the two contact pieces are no longer in contact, indicating that the mold is dislocated, so that the control unit can receive the message in the first time and use it to notify the staff, so as to avoid the mold dislocation so that the staff cannot be notified in time, resulting in accurate detection of the bolts fixed on the mold, thereby improving the use effect of the device; When the mold makes the retaining ring body 12 connected with the plurality of guide cylinders 11 move away from the rectangular box 3 during installation, the bending plates 15 on both sides of the retaining ring body 12 are driven to move away from the moment sliding column 35, so that the bending plates 15 are separated from the moment cross block 36 and are no longer connected to the moment slot 41, thereby releasing the limit setting of the moment cross block 36, so that the moment spring 40 originally in the buffer state is reset, thereby driving the moment cross block 36 to reset and move, so that under the action of the locking square column 37 and the locking spring 39, the U-shaped clamping plate 38 moves towards the direction of the rectangular box 3. Since the mold moves to the maximum position at this time, that is, when the U-shaped clamping plate 38 is When the plate 38 is reset, the U-shaped clamping plate 38 is aligned with the side of the mold close to the detection cavity, so that the two U-shaped clamping plates 38 move relatively and contact the two sides of the mold respectively, thereby clamping the mold in the rectangular box 3, and completing the installation operation of the mold. Since the strength of the torque spring 40 is greater than the locking spring 39, when the U-shaped clamping plate 38 contacts the side of the mold, the torque spring 40 has not been completely reset at this time. Through the continued reset of the torque spring 40, the torque cross block 36 is driven to continue to move, so that it continues to move on the locking square column 37, so that the locking spring 39 is in a buffering state, thereby continuously applying force to the U-shaped clamping plate 38, strengthening the U-shaped clamp The strength of the connection between the plate 38 and the mold prevents the mold from being dislocated during use, thereby improving the installation effect of the device on the mold; when the U-shaped clamping plate 38 completes the clamping of the mold, the operator no longer contacts the mold to continue to apply force, so that the guide spring 14, which was originally in a buffer state, wants to reset, but because the mold is limited to one side away from the retaining ring body 12 by the baffle, the guide spring 14 cannot reset and move, thereby further limiting the mold, thereby limiting the mold in multiple directions, avoiding dislocation, displacement, shaking, etc. of the mold after installation, further improving the installation effect of the device on the mold, and avoiding The bolts fixed on the mold shake or become unstable when being detected, thereby further improving the detection effect of the device; and the above-mentioned installation steps are convenient and quick. You only need to place the mold in the rectangular box 3 with one hand and press it to complete the installation operation of the mold.

By pushing the reciprocating movement of the square plate 22, the gas storage bag 27 is The continuous expansion indicates that gas is continuously entering the interior thereof. When the mold is installed, the push square plate 22 is no longer moved, so that the gas storage bag 27 is in the current state. When the device needs to detect the bolt, it only needs to connect the head of the bolt with the mold so that the two fit together, so that the bolt can be stably detected by the device. Since the contact end of the ventilation pipe 30 and the ventilation hose 28 is provided with a valve (not shown in the figure), when the bolt is fixed, the control unit sends a signal to open the valve at the ventilation pipe 30, so that the gas storage bag 27 has a venting channel, so that the internal gas continues to flow out. The gas is injected into the ventilation duct 30, so that the deformed air bag 27 is gradually reset, and the gas is ejected through the high-pressure nozzle 31. The gas acts on the fixed bolts to clean the bolts, and can clean the impurities or dust adhering to the surface and thread of the bolts, thereby avoiding the presence of these impurities affecting the detection results of the device on the bolts, improving the accuracy of the device on the bolt detection, further reducing the work intensity of the staff, reducing the limitations of the device when in use, avoiding the need for the staff to add extra power sources, resulting in an increase in the use cost, and thus improving the use effect of the device.

[0022] The limiting positioning unit of this embodiment includes a rotating block 42 threadedly mounted on the rotating screw rod 4, and two symmetrical rotating slides 43 are passed through the top of the rotating block 42, and the rotating slides 43 are fixedly mounted on the rectangular box 3; the rotating slides 43 are slidably matched with the rotating block 42; U-shaped slides 44 are also provided on both sides of the rotating block 42, and the opening of the U-shaped slides 44 faces the torque slide 35; auxiliary square columns 45 are slidably connected at both ends of the U-shaped slide 44, and the two auxiliary square columns 45 are commonly connected to an auxiliary cross plate 46; an auxiliary spring is provided in the U-shaped slide 44 47, one end of the auxiliary spring 47 is fixedly connected to the auxiliary square column 45, and the other end is fixedly connected to the inner wall of the U-shaped slide 44; the top of the auxiliary horizontal plate 46 is connected through a driving slide column 48, and the driving slide column 48 is slidably matched with the auxiliary horizontal plate 46; the end of the driving slide column 48 close to the moment slide column 35 is installed with a resistance friction plate 49, and the side of the resistance friction plate 49 close to the moment horizontal block 36 is set as an inclined surface; the driving slide column 48 is sleeved with a driving spring 50, one end of the driving spring 50 is fixedly connected to the resistance friction plate 49, and the other end is fixedly connected to the auxiliary horizontal plate 46; When the compound toothed disc 6 rotates, it drives the meshing rotating gear 5 to rotate, so that the rotating screw 4 on it rotates and drives the threaded rotating block 42 to move within the limit position at the rotating slide post 43, so that the two rotating blocks 42 move relative to each other, that is, both move toward the rectangular box 3, thereby driving the U-shaped slide 44 to move toward the direction of the moment cross block 36, so that the U-shaped slide 44 drives the auxiliary cross plate 46 to move under the action of the auxiliary square column 45 and the auxiliary spring 47, so that under the action of the driving slide post 48, the resistance friction plate 49 on it is close to the driving slide post 48. The near moment cross block 36 moves and contacts, so that the resistance friction plate 49 can apply a downward force to the reset moment cross block 36, so that the moment cross block 36 can be limited to the current position, and the U-shaped clamping plate 38 can be prevented from being dislocated due to the movement of the moment cross block 36 when clamping the mold, thereby increasing the friction force between the moment cross block 36 and the moment slide column 35, so that the device can further limit the mold, and prevent the mold from being dislocated, shaking, etc. after installation. The bolt detection process reduces the limitations of the device when in use; when the resistance friction plate 49 contacts the moment cross block 36 and continues to drive the auxiliary cross plate 46 to move downward through the U-shaped slide 44, it is moved to the upper limit position of the driving slide column 48, so that the driving spring 50 is in a buffering state, further strengthening the connection between the resistance friction plate 49 and the moment cross block 36, and improving the installation effect of the device on the mold; at the same time, since the side of the resistance friction plate 49 close to the moment cross block 36 is an inclined surface, if the movement speed of the resistance friction plate 49 is greater than the moment cross block 36, When the horizontal block 36 is in contact with the side surface of the resistance friction plate 49, it means that the torque horizontal block 36 first contacts the side surface of the resistance friction plate 49, so that the torque horizontal block 36 contacts the inclined surface of the resistance friction plate 49, thereby exerting an upward force on it, so that the resistance friction plate 49 moves close to the auxiliary horizontal plate 46 through the driving sliding column 48, so that the driving spring 50 is in a buffering state, so that the bottom surface of the resistance friction plate 49 contacts the top surface of the torque horizontal block 36, and the position of the torque horizontal block 36 is limited, further avoiding its position change, thereby improving the use effect of the device.

[0023] The pressure-applying mechanism of this embodiment includes a U-shaped square seat 51 installed on the end of the limit slide 34, and a trigger wheel 52 is installed in the U-shaped square seat 51; a limit spring 53 is sleeved on the limit slide 34, one end of the limit spring 53 is fixedly connected to the bending base 33, and the other end is fixedly connected to the U-shaped square seat 51; a linkage base plate 54 is also installed on the rectangular box 3, and a linkage slide post 55 is connected to the top of the linkage base plate 54, and the linkage slide post 55 is slidably matched with the linkage base plate 54; A linkage inclined block 56 is also installed on the top of the linkage slide post 55, and the linkage inclined block 56 is located at the bottom of the trigger wheel 52; the inclined surface of the linkage inclined block 56 faces the trigger wheel 52 and the two are arranged in close contact; a linkage spring 57 is sleeved on the linkage slide post 55, one end of the linkage spring 57 is fixedly connected to the linkage base plate 54, and the other end is fixedly connected to the linkage inclined block 56, and one end of the extended square rod 58 is also installed on the linkage inclined block 56, and the other end of the extended square rod 58 is located at the top of the auxiliary horizontal plate 46; When the ventilation pipe 30 is ejecting gas, and a valve (not shown) is provided in the bending pipe 32, the valve in the bending pipe 32 is opened, so that part of the gas in the ventilation pipe 30 is diverted to the bending pipe 32, so that the gas contacts one end of the limit slide 34 in the bending pipe 32, so that the gas is pressed at the output end of the bending pipe 32 and moves outward, so that the trigger wheel 52 on the other end of the limit slide 34 moves away from the bending pipe 32, so that the limit spring 53 is in a buffer state, so that the moving trigger wheel 52 contacts the stop spring 53 located therein. The inclined surface of the linkage inclined block 56 below is provided with a downward pressure, so that the linkage inclined block 56 is limitedly moved at the linkage base plate 54 through the linkage sliding column 55, so that the linkage spring 57 is in a buffering state, so as to drive one end of the extended square rod 58 to move downward, so that the other end of the extended square rod 58 will contact the top of the auxiliary horizontal plate 46 when it moves downward, thereby applying a downward pressure to it, so that the auxiliary horizontal plate 46 drives the auxiliary square column 45 to move within the U-shaped slide cylinder 44, so that the auxiliary spring 47 is in a buffering state, so that the auxiliary horizontal plate 46 continues to move at the driving sliding column 48. The resistance friction plate 49 is moved downward, thereby continuously increasing the pressure on the resistance friction plate 49, so that the connection strength between the resistance friction plate 49 and the moment cross block 36 is increased, further avoiding the displacement of the moment cross block 36 during use, which may cause the bolts on the mold to be unstable during detection. At the same time, it can also ensure that the resistance friction plate 49 is in contact with the moment cross block 36. If the two are not in contact, the resistance friction plate 49 is moved downward to make it contact with the moment cross block 36, so as to avoid the instability of the mold after installation due to the inability to contact between the two, thereby improving the use effect of the device. At the same time, when the moment cross block 36 and the resistance friction plate 49 are fully in contact, the valve in the bending pipe 32 is closed, so that the moment cross block 36 and the resistance friction plate 49 are always in the current contact state, avoiding the outflow of gas in the bending pipe 32 causing the linkage inclined block 56 to reset, and further operating the movement of the resistance friction plate 49, that is, its contact with the moment cross block 36, is carried out when the bolts are fixed and need to be detected, which reduces the limitations of the device during use, and avoids the limit stop unit failing to limit the elastic clamping control device, resulting in poor safety of the device during use.

Install the mold on the device through the spring-loaded clamping control device, and place the bolt head to be tested in the mold for fixing; S2.
