[0001] The invention belongs to the field of clamp processing devices, in particular to an automatic locking and detection device for a clamp. Background Art

[0002] After the clamp is assembled, the free end of the clamp band needs to be inserted into the clamp shell, and the worm is screwed to lock it. In the prior art, this operation is done manually, that is, the free end of the curled clamp band needs to be inserted into the clamp shell, and then the worm is screwed by hand to complete the locking under the meshing of the worm and the clamp teeth. This operation is labor-intensive and has low tightening efficiency.

[0003] At the same time, the existing specifications require that after tightening, the number of teeth exposed when the band passes through the hoop shell is three. This means that after the clamp is tightened, the teeth need to be inspected, which is a cumbersome process. In addition, manual inspection is prone to missed inspections and wrong inspections, which affects product quality. Summary of the invention

DETAILED DESCRIPTION

[0029] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings:

[0030] The invention discloses an automatic locking and detection device for a clamp, the innovation of which lies in that it comprises an automatic threading and locking unit and a locking amount detection unit; the automatic threading and locking unit is used for threading the free end of the clamp into a clamp shell, and under the action of a worm, the clamp is inserted into the clamp shell; the locking amount detection unit is used for detecting the clamp shell exposed at the right end of the clamp shell to meet the assembly requirements.

[0031] The device is installed on a horizontal installation plate 24 , and the horizontal installation plate is a structure with a notch at the front, and the notch is a feed opening 25 .

[0032] The automatic belt threading and locking unit comprises a horizontal mounting plate, a mounting vertical plate 4, a clamp fixing mechanism 5, a clamp belt threading mechanism and a clamp worm locking mechanism. A mounting vertical plate is installed at the rear left end of the loading and unloading opening of the horizontal mounting plate, and a clamp fixing mechanism is installed at the upper position of the mounting vertical plate.

[0033] The clamp fixing mechanism includes a clamping cylinder, a clamp shell clamping block 18, a clamp shell support block 19, and a support block telescopic cylinder 26. A telescopic hole is provided at the upper position of the mounting vertical plate, and a clamp shell support block is installed in the telescopic hole. The clamp shell support block is driven by the support block telescopic cylinder to telescope forward and backward in the telescopic hole. A clamp shell clamping block driven to rise and fall by the clamping cylinder is provided directly above the extended clamp shell support block.

[0034] After the clamp is placed on the hoop shell support block, the hoop shell pressing block descends and presses on the hoop shell through the hoop shell profiling groove provided on the lower end surface of the hoop shell pressing block, so that the upper end of the clamp is fixed; after threading and locking are completed, the support block telescopic cylinder drives the hoop shell support block to retract, and the clamp completes blanking.

[0035] The described clamp threading mechanism includes a left pushing block 21, an upper support block 23, a right pushing block 31 and an arc guide block 17. A left pushing block driven by a left pushing cylinder 27 is provided right below the hoop shell support block, and a right pushing block driven by a right pushing cylinder 15 is provided left below the hoop shell support block. An arc guide block is provided on the left side of the hoop shell support block, and a guide groove 36 is provided on the bottom surface of the arc guide block. The upper end slot of the guide groove is opposite to the position where threading is to be performed. An upper support block is provided at the lower part of the hoop shell support block, and the upper support block is driven by a moving-out assembly. The moving-out assembly includes a front pushing cylinder 28, a moving-out frame 29 and an upper support cylinder 13. A front pushing cylinder is provided below the horizontal mounting plate, a moving-out frame is installed at the front end of the front pushing cylinder, the moving-out frame slides on a slideway 30 placed at the bottom of the horizontal mounting frame, an upper support cylinder is installed on the moving-out frame, and an upper support block is installed on the upper support cylinder;

[0036] The working principle of the threading operation is as follows:

[0037] The hoop shell is fixed, the left pushing block pushes the hoop band of the clamp to move leftward, so that the free end of the hoop band is caught in the guide groove of the arc guide block, and then the right pushing block pushes rightward, so that the free end of the hoop band is inserted into the hoop shell along the guide of the arc guide block. In order to make the insertion more accurate, a belt pressing block 34 is also designed at the position where it is about to enter the hoop shell. The described clamp threading mechanism also includes a belt pressing block. A belt pressing block linked to it is provided at the left end of the hoop shell pressing block. The belt pressing block is composed of a block body and a hoop shell head groove provided at the bottom of the block body. The protruding parts on both sides of the hoop shell groove form a hoop band pressing head 32. The hoop band is inserted into the hoop shell under the guidance of the hoop band pressing head, and the gap between the hoop band pressing head and the hoop shell support block forms a threading gap 35.

[0038] The described clamp worm locking mechanism 6 includes a left moving frame 7, a locking motor 10 and a locking sleeve 20. A left pushing cylinder 27 is installed on the right horizontal mounting plate of the installation vertical frame. A left moving frame is driven and installed on the left pushing cylinder, and a locking sleeve driven by the locking motor is installed on the left moving frame; An extending frame is provided below the locking sleeve on the left moving frame, and a left pushing block is installed on the extending frame 22.

[0039] After threading is completed, the locking motor drives the locking sleeve to rotate, thereby driving the worm in the hoop shell to rotate. Under the meshing of the worm and the hoop teeth, the free end of the hoop band is made to pass through in the hoop shell.

[0040] To avoid safety problems caused by direct manual feeding and misoperations, a feeding unit 12 is installed at the front end of the blanking port. This feeding unit is installed in front of the automatic tape threading and locking unit. The feeding unit includes a feeding slide rail 3, a feeding slider, left and right feeding cylinders 9, front and rear feeding cylinders 2, and a pneumatic gripper 1. A feeding slide rail is installed directly in front of the installation vertical plate, and a feeding slider is installed on the feeding slide rail. The feeding slider is driven by the left and right feeding cylinders. A front and rear feeding cylinder is installed on the feeding slider, and a pneumatic gripper is driven and installed on the front and rear feeding cylinders.

[0041] During operation, the left and right feeding cylinders push out the pneumatic gripper to complete manual feeding. Then, the left and right feeding cylinders retract. When the clamp is directly opposite the shell pushing block of the clamp shell, the front and rear feeding cylinders act to place the clamp shell of the clamp on the shell supporting block and then retract.

[0042] The locking amount detection unit includes an optical fiber sensor 16. A detection through hole 33 is provided on the end face of the arc-shaped guide block. An optical fiber sensor is installed on the installation vertical plate, and the probe of the optical fiber sensor faces the detection through hole.

[0043] When the free end of the hoop band moves within the arc-shaped guide block, the optical fiber sensor starts to record the number of hoop teeth passing through, thereby calculating the number of hoop teeth exposed at the right end of the clamp shell, achieving the purpose of on-line detection and avoiding problems such as low detection accuracy and missed detection caused by manual detection.

[0044] The detection of torque is also an important part of clamp detection, which directly reflects whether the worm can mesh with the hoop teeth and determines the quality of the product. To prevent unqualified products with insufficient torque from being mixed into qualified products, the present invention designs a defective product diversion mechanism. The defective product diversion mechanism includes a torque sensor 8, a diversion cylinder 11, and a diversion hopper 14 with left and right openings. A diversion hopper driven by the diversion cylinder is installed on the horizontal installation plate at the front right end of the installation support frame. After the diversion hopper extends, it is located at the blanking port. A torque sensor is installed on the locking motor, and the torque sensor is signal-connected to the diversion cylinder.

[0045] When the diversion cylinder detects and receives a signal of unqualified products, it will push out the diversion hopper, so that the falling materials will be collected in another place along the guidance of the diversion hopper, avoiding being mixed into the qualified product collection basket directly below the blanking port.

[0046] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art can understand that: various substitutions, changes, and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the content disclosed in the embodiments and drawings.
