Description

Technical Field

[0001] The invention relates to the technical field of quick-working clamping processing equipment, in particular to a quick-working clamping flat ring machine. Background Art

[0002] As a widely used office tool, the structure and function of quick-release folders directly affect the reliability of document binding and the convenience of operation. Figure 1 As shown in the figure, the core structure of the quick-release clamp includes a flat hole on the clamp body and a matching metal flat ring. The processing accuracy of the flat hole and the quality of the metal flat ring are the key links that determine the performance of the product. The traditional production process generally adopts a step-by-step processing mode, that is, first a flat hole is opened on the clamp body by a punching device, and then the metal flat ring is manually set into the flat hole, and then the metal flat ring is fixed in the flat hole by a stamping device. However, this type of process has significant technical defects in terms of efficiency, accuracy and consistency, as shown below:

[0003] 1. Separation of processes leads to low efficiency: the existing technology relies on two sets of independent equipment for punching and ferrule operation in steps. The workpiece needs to be positioned and transferred many times, which takes a long time to produce. In addition, the speed of manual ferrule setting depends entirely on the workers' operating experience, resulting in the inability to guarantee production capacity.

[0004] 2. Insufficient processing accuracy affects product performance: The size, position accuracy and shape standardization of the flat hole directly affect the effect of the metal flat ring. Traditional punching equipment will produce deviations due to mechanical vibration, resulting in uneven clearance between the flat hole and the flat ring. In addition, if the metal flat ring is not strictly aligned with the flat hole during installation, it is easy to cause problems such as the metal ring getting stuck when the clamp is closed, which seriously affects the user experience;

[0005] 3. Poor process adaptability and flexibility: As the market demand for diversified specifications of quick-release clamps increases, traditional equipment has a fixed structure and parameter adjustment relies on manual mold replacement or mechanical reconstruction, resulting in low model switching efficiency and high cost, making it difficult to adapt to small-batch and multi-batch flexible production needs;

[0006] 4. Low safety: When the operator places the metal flat ring in the flat hole, it is always under the punch of the stamping equipment, which poses a great safety hazard.

[0007] In summary, the step-by-step process of flat hole processing and metal flat ring sleeve setting in the existing technology can no longer meet the production requirements of high efficiency, high precision and high consistency. To this end, we propose a fast-working flat ring clamping machine to achieve integrated and precise processing of flat hole punching and metal flat ring sleeve setting. Summary of the invention

A straight groove 901 is provided on the support bar 9. An adaptor 902 is provided in each of the straight grooves 901. The number of the adaptor 902 is twice that of the convex strips 803. Two adaptors 902 form a group. The two adaptors 902 in a single group are respectively located on both sides above one of the convex strips 803. The adaptor 902 includes a rotating rod 9 respectively installed in the two straight grooves 901 through a rotating shaft. 021, the rotating rod 9021 is perpendicular to the top surface of the machine table 1, and the ends of the two rotating rods 9021 close to the machine table 1 are connected by a fixed block 9022, and the same side of the two fixed blocks 9022 in the single set of adaptors 902 are connected by a tension spring 9023, and the opposite sides of the fixed blocks 9022 in the single set of adaptors 902 are provided with placement grooves 9024, and the placement grooves 9024 support the pre-processed metal flat ring, and when the pressure head 11 moves downward, the metal flat ring in contact with it is sleeved on the pressure head 11;

[0062] The servo motor 601 is started, driving the eccentric disk 602 to rotate. During the rotation of the eccentric disk 602, it drives the connecting cover 603 to move up and down, and synchronously drives the first connecting rod 605 through the second connecting rod 606 to reciprocate up and down at one end close to the second connecting rod 606.

[0066] The staff only needs to place the quick-working clamp on the machine 1. When the quick-working clamp needs to be punched, slide the quick-working clamp so that its top edge is in contact with the cross bar 102. The top edge of the quick-working clamp adjusts the second trigger lever 204 on the cross bar 102, so that the first trigger lever 202 is perpendicular to the machine 1, and then slide the quick-working clamp to the left so that the left edge of the quick-working clamp is in contact with the rightmost side of the left limit block 2. At this time, the first trigger lever 202 on the left limit block 2 is also adjusted, and is detected by the driving mechanism 6 corresponding to the punching linkage mechanism 7, which drives the punching linkage mechanism 7 to punch the quick-working clamp. Similarly, when punching the metal flat ring, the right edge of the quick-working clamp is in contact with the leftmost side of the right limit block 2, and the top edge is in contact with the cross bar 102, triggering the driving mechanism 6 corresponding to the punching linkage mechanism 12.

Under the action of its own gravity, the metal flat rings slide down along the guide rail 1003. The electronic detector 1004 detects the number of metal flat rings in the guide rail 1003 in real time. When it detects that no metal flat rings pass through for a long time, an alarm is issued to remind the staff to repair.

[0069] The auxiliary part 1005 includes a telescopic cylinder 10051 installed on the bracket body 101, and a rod 2 10052 is connected to the telescopic cylinder 10051, and the rod 2 10052 is vertically arranged with the telescopic cylinder 10051. A rod 3 10053 is installed on the top of the rod 2 10052, and the rod 3 10053 is in an "E" shape. A straight hole 10054 is provided on the transmission plate 1002, and the middle end of the rod 3 10053 is slidably arranged with the straight hole 10054.

A third sieve block 10057 is fixed on the middle end of rod three 10053. The top of the third sieve block 10057 close to the second sieve block 10056 and the bottom close to the first sieve block 10055 are both protruding triangular shapes. The auxiliary part 1005 also includes a support seat 10058 installed on the transmission plate 1002, and an air pipe 10059 is relatively penetrated and installed on the support seat 10058. One end of the two air pipes 10059 is located at the bottom end of the guide rail 1003, and both are equipped with an air nozzle 100510, corresponding to one of the guide rails 1003, and the other end is connected through a three-way head 100511, and the end of the three-way head 100511 that is not connected to the air pipe 10059 is connected to the pneumatic system through a pipe 100512.

[0070] Under default conditions, the first sieve block 10055 does not contact the guide rail 1003, the triangular portion protruding from the bottom end of the second sieve block 10056 covers the guide rail 1003 close to itself, and intercepts the guide rail 1003, while the triangular portion of the top end of the third sieve block 10057 close to the second sieve block 10056 does not contact the guide rail 1003, at this time, the guide rail 1003 close to the second sieve block 10056 is only intercepted by the second sieve block 10056, and the triangular portion of the bottom end of the third sieve block 10057 close to the first sieve block 10055 intercepts the other guide rail 1003;

[0071] When it is necessary to load the material, the telescopic cylinder 10051 is turned on, driving the second rod 10052 to move in the slotted hole 10054, the second rod 10052 drives the third rod 10053 to move, and the third rod 10053 simultaneously drives the first sieve block 10055, the second sieve block 10056, and the third sieve block 10057 to move. At this time, the triangular part at the top of the first sieve block 10055 covers the guide rail 1003 close to itself, intercepts the metal flat ring in the guide rail 1003 above itself, and the third sieve block 10057 is moved.

[0072] The stamping linkage mechanism 12 includes a second connecting seat 1201 located directly above the pressing head 11. The second connecting seat 1201 is rotatably connected to one end of the first connecting rod 605 closest to itself. A second sliding bar 1202 is installed on the second connecting seat 1201. There are two second sliding bars 1202, which are respectively located directly above the two pressing heads 11. The second sliding bars 1202 are vertically arranged to the top surface of the machine 1, and are slidably arranged between the bracket body 101. The cross-section of the second sliding bars 1202 is a straight-edged ellipse, and a hydraulic rod 1203 is installed through the inside. The hydraulic rod 1203 is fixed to one of the pressing heads 11 respectively.

[0073] Driven by the corresponding driving mechanism 6 of the stamping linkage mechanism 12, the second connecting seat 1201 performs an up and down reciprocating motion, and the second connecting seat 1201 synchronously drives the two second sliding bars 1202 to perform an up and down reciprocating motion. During the downward movement of the second sliding bar 1202, the two pressing heads 11 respectively penetrate the metal flat rings in the placement grooves 9024 of their respective corresponding fixed blocks 9022. At this time, the metal flat rings are sleeved on the pressing head 11. As the second sliding bar 1202 continues to move downward, the second sliding bar 1202 squeezes the two fixed blocks 9022 of the single-group adapter 902. During the process of the fixed blocks 9022 moving away from each other, the tension spring 9023 is stretched. The two fixed blocks 9022 move away from each other to release the restriction on the metal flat rings. Subsequently, the hydraulic rod 1203 extends, driving the pressing head 11 and the metal flat rings on the pressing head 11 to move downward. After 11 and the convex strip 803 are fitted, the second slide bar 1202 continues to move downward, and the hydraulic rod 1203 is retracted at the same speed. Since the downward movement of the second slide bar 1202 will drive the entire hydraulic rod 1203 to move downward, this distance is offset, that is, the pressure head 11 is always in contact with the convex strip 803. As the second slide bar 1202 moves downward, the metal flat ring is driven to separate from the pressure head 11 and fall into the flat hole of the quick-working clamp. Finally, the second slide bar 1202 punches the metal flat ring. Under the guidance of the rounded corners at the top of the convex strip 803, the metal flat ring is fixed in the flat hole, completing the installation of the metal flat ring and the flat hole. Subsequently, the various components are reset. After the second slide bar 1202 is reset, the tension spring 9023 loses the obstruction of the second slide bar 1202, and synchronously drives the adaptation part 902 to reset. The staff can remove the processed quick-working clamp and repeat the above processing operation.
