[0001] The utility model relates to the technical field of bidirectional positioning fixtures, in particular to a tooling fixture with a bidirectional positioning function. Background Art
[0002] In the process of metal processing, it is often encountered that batches of products of the same specifications need to be processed by facing, milling grooves, and rough cutting. In order to reduce the processing time, it is often necessary to use a tooling fixture with two-way positioning to clamp the workpiece.
[0003] According to the prior art patent number CN 219336938U, a bidirectional clamp that is easy to operate is simple to operate and has low manufacturing cost. However, before clamping the workpiece, it is necessary to manually unscrew the two locking screws to release the lock of the fixed rod, and then adjust the distance position of the fixed rod. This process is time-consuming and laborious.
[0004] Therefore, a tooling fixture with a bidirectional positioning function is needed to solve the problem in the prior art that it is time-consuming and laborious to respectively unscrew two locking bolts during the process of adjusting the fixing rod. Utility Model Content
[0005] In order to solve the above technical problems, a tooling fixture with a bidirectional positioning function is provided, which solves the problem in the prior art that it is time-consuming and laborious to respectively unscrew two locking bolts during the process of adjusting the fixing rod.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: a tooling fixture with a bidirectional positioning function, including a table board, two fixing rods in a mouth shape and symmetrically slidably arranged on the top surface of the table board, and a cylinder installed under the table board, an OK clamp is arranged between the two fixing rods, and the OK clamp is composed of a fan-shaped push block and two inclined blocks, and the two inclined blocks are respectively slidably arranged on the two side oblique edges of the fan-shaped push block, and the telescopic rod of the cylinder slides through the table board and is fixed to the center of the bottom surface of the fan-shaped push block, and is characterized in that: an automatic fixing mechanism for fixing the fixing rod is arranged between the cylinder and the table board, and an adjustment limiting mechanism is arranged on one side of the fixing rod.
[0007] Preferably, the automatic fixing mechanism includes a transmission block slidably mounted on the rod body of the cylinder telescopic rod, pull rods are fixed at both ends of the transmission block, the ends of the pull rods sequentially pass through the table top and the fixed rod and are fixed with anti-slip blocks, the anti-slip blocks are abutted against the fixed rod, a spring is mounted on the rod body of the cylinder telescopic rod, the spring is located above the transmission block, one end of the spring is fixed to the transmission block, and the other end of the spring is fixed with a fixing block annularly mounted on the cylinder rod body.
[0008] Preferably, the adjustment and limiting mechanism includes two tooth plates staggeredly distributed front and back on the top surface of the table top and a transmission component arranged between the two tooth plates, and a linkage block is fixed between the two tooth plates and the corresponding fixing rods.
[0009] Preferably, the transmission component comprises a gear disposed between the two tooth plates, two sides of the gear are meshed with the tooth plates, and a handle is fixed at the center of the top surface of the gear.
[0010] Preferably, a limiting block is provided on one side of the two tooth plates away from the gear, and the limiting block is fixed to the top surface of the table top and is slidably connected to one side of the tooth plate.
[0011] Compared with the prior art, the advantages of the utility model are:
[0012] (1) Through the setting of the automatic fixing mechanism, the cylinder telescopic rod pulls the fan-shaped push block of the OK clamp while also pulling the fixed block. The fixed block drives the spring to push the transmission block down along the cylinder telescopic rod, and drives the pull rod to descend synchronously. The descent of the pull rod drives the anti-sliding block to descend until it contacts the top of the fixed rod, thereby achieving the clamping and fixing of the fixed rod by the anti-sliding block. In this way, the problem of the prior art that it is time-consuming and laborious to respectively unscrew the two locking bolts during the adjustment of the fixed rod can be solved.
[0013] (2) By adjusting the setting of the limiting mechanism and the transmission components, when it is necessary to adjust the distance between the two fixed rods and the OK clamp, the handle can be turned to drive the gears to rotate synchronously. During this process, the two gear plates are meshed with the teeth on both sides of the gears to move relative to or away from each other, and the two fixed rods are driven to move synchronously through the linkage block. In this way, the need for workers to adjust the distance between the two fixed rods and the OK clamp separately before placing the workpiece can be solved.
[0014] (3) By setting the limiting block, the tooth plate drives the linkage block and the fixed rod to move synchronously. In this process, the limiting block is used to limit the tooth plate through the linkage block to limit the movement trajectory of the fixed rod, thereby preventing the fixed rod from being deflected due to the worker touching it when placing the workpiece.

[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.
[0021] Reference Figure 1 , Figure 2 and Figure 3 As shown, a tooling fixture with a bidirectional positioning function includes a table top 1, two fixing rods 3 in a square shape and symmetrically slidably arranged on the top surface of the table top 1, and a cylinder 4 installed below the table top 1, an OK fixture 2 is arranged between the two fixing rods 3, the OK fixture 2 is composed of a fan-shaped push block and two inclined blocks, the two inclined blocks are respectively slidably arranged on the two side oblique edges of the fan-shaped push block, and the telescopic rod of the cylinder 4 slides through the table top 1 and is fixed to the center of the bottom surface of the fan-shaped push block;
[0022] Through the setting of the OK clamp 2, the fixed rod 3 and the cylinder 4, the fixed rod 3 can be adjusted to a suitable distance from the OK clamp 2 according to the size of the workpiece, and the two workpieces are placed between the fixed rod 3 and the oblique block of the OK clamp 2 respectively, and then the cylinder 4 is started, and the fan-shaped push block is pulled by the telescopic rod of the cylinder 4, so that the oblique blocks on both sides are pushed to move, and then the workpiece is pushed to resist the fixed rod 3. After the pulling force of the cylinder 4 ends, the fan-shaped push block rises and drives the push blocks on both sides to shrink until the OK clamp 2 pushes the workpiece to resist the fixed rod 3, thereby realizing the fixed clamping of the workpiece. After closing the cylinder 4, the pulling force of the telescopic rod of the cylinder 4 on the OK clamp 2 ends, so that the OK clamp 2 releases the fixed clamping state of the workpiece.
[0023] In addition, referring to the existing patent announcement number CN 217914842 U, the OK clamp parallel side top vise, it can be seen from the above patent content that the OK clamp 2 is mainly composed of a fan-shaped push block and two inclined blocks. As a device known in the prior art, this scheme only briefly describes its working principle, and does not introduce its internal structure and connection method in detail. For details, please refer to the above-mentioned patent documents.
[0024] However, in practice, the fixing rod 3 in the prior art is installed on the top surface of the table top 1 by means of bolts. Therefore, before clamping the workpiece, it is necessary to manually unscrew the two locking bolts to release the lock on the fixing rod 3, and then adjust the distance position of the fixing rod 3. This process is time-consuming and labor-intensive.
[0025] Further, refer to Figure 3As shown, it is worth noting that an automatic fixing mechanism for fixing the fixing rod 3 is provided between the cylinder 4 and the table top 1;
[0026] The automatic fixing mechanism includes a transmission block 13 slidably mounted on the telescopic rod of the cylinder 4, and pull rods 12 are fixed at both ends of the transmission block 13. The ends of the pull rods 12 pass through the table top 1 and the fixed rod 3 in sequence and are fixed with an anti-sliding block 11. The anti-sliding block 11 abuts against the fixed rod 3. A spring 6 is mounted on the rod of the telescopic rod of the cylinder 4. The spring 6 is located above the transmission block 13. One end of the spring 6 is fixed to the transmission block 13, and the other end of the spring 6 is fixed with a fixing block 14 which is annularly mounted on the rod of the cylinder 4.
[0027] By setting the automatic fixing mechanism, before the workpiece needs to be clamped, the fixing rod 3 is moved to a suitable distance from the OK clamp 2 according to the specifications of the workpiece, and then the cylinder 4 is started. The telescopic rod of the cylinder 4 pulls the fan-shaped push block of the OK clamp 2 while also pulling the fixing block 14. The fixing block 14 drives the spring 6 to push the transmission block 13 down along the telescopic rod of the cylinder 4, and drives the pull rod 12 to descend synchronously. The descent of the pull rod 12 drives the anti-sliding block 11 to descend until it contacts the top of the fixing rod 3. In this way, the fixing rod 3 is clamped and fixed on the top surface of the table board 1 by pressing down the anti-sliding block 11, and then the spring 6 continues to be compressed under the downward pressure of the fixing block 14 to fix it. The telescopic rod of the cylinder 4 on block 14 continues to contract, driving the fan-shaped push block of the OK clamp 2 to continue to descend until the oblique blocks on both sides of the OK clamp 2 push the workpiece to abut against the fixed rod 3, and then after the anti-sliding block 11 clamps and fixes the fixed rod 3, the oblique blocks on both sides of the OK clamp 2 push the workpiece to abut against the fixed rod 3 to clamp the workpiece. In this way, the problem in the prior art that the distance between the fixed rod 3 and the OK clamp 2 needs to be adjusted according to the specifications of the workpiece when clamping the workpiece can be solved. In this process, it is necessary to manually unscrew the two locking bolts to release the lock of the fixed rod 3, and then adjust the distance position of the fixed rod 3. This operation process is time-consuming and labor-intensive.
[0028] After using it for a period of time, it was found that workers needed to adjust the distance between the two fixed rods 3 and the OK clamp 2 respectively before placing the workpiece, and the fixed rod 3 was in a non-fixed state during the process of placing the workpiece. When placing the workpiece, the worker accidentally touched the fixed rod 3, causing the fixed rod 3 to deflect.
[0029] In view of this, in order to solve the above problems, refer to Figures 1 to 3 As shown, it is worth noting that an adjustment and limiting mechanism is provided on one side of the fixing rod 3 .
[0030] The adjustment and limiting mechanism includes two tooth plates 7 staggeredly distributed on the top surface of the table board 1 and a transmission component arranged between the two tooth plates 7. A linkage block 5 is fixed between the two tooth plates 7 and the corresponding fixing rods 3.
[0031] The transmission component includes a gear 9 disposed between two toothed plates 7 , the two sides of the gear 9 are meshed with the toothed plates 7 , and a rotating handle 10 is fixed at the center of the top surface of the gear 9 .
[0032] By adjusting the settings of the limiting mechanism and the transmission components, when it is necessary to adjust the distance between the two fixed rods 3 and the OK clamp 2, the handle 10 can be rotated to drive the gear 9 to rotate synchronously. During this process, the two tooth plates 7 are meshed with the teeth on both sides of the gear 9 to move relative to or away from each other, and the two fixed rods 3 are driven to move synchronously through the connecting block 5. In this way, the need for workers to separately adjust the distance between the two fixed rods 3 and the OK clamp 2 before placing the workpiece can be solved.
[0033] Further, refer to Figures 1 to 3 As shown, it is worth noting that a limiting block 8 is provided on one side of the two tooth plates 7 away from the gear 9 , and the limiting block 8 is fixed to the top surface of the table top 1 and is slidably connected to one side of the tooth plate 7 .
[0034] By setting the limiting block 8, the tooth plate 7 drives the linkage block 5 and the fixed rod 3 to move synchronously. In this process, the limiting block 8 is used to limit the tooth plate 7 through the linkage block 5 to limit the movement trajectory of the fixed rod 3, thereby preventing the fixed rod 3 from being deflected due to the worker touching it when placing the workpiece.
