[0022] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the following combines the drawings and embodiment, and further detailedly explains the utility model. It should be understood that the specific embodiment described here is only used to explain the utility model, and is not used to limit the utility model.

[0023] Reference Figure 1 And Figure 2 As shown in the figure, an embodiment of the utility model is a limit auxiliary chuck matched with a bending machine, which comprises a bearing seat 1 and a limit block 2. The bearing seat 1 is arranged on the input side of the bending machine. The limit block 2 is installed on the bearing seat 1. The limit block 2 is generally circular or rectangular. The lower end of the slider is welded to the surface of the bearing seat 1, and the bearing seat 1 provides stable support for the limit block 2. The bearing seat 1 is generally fixed on the input side of the bending machine. Two or more sliders 3 are arranged on the limit block 2. The moving direction of the slider 3 is towards the geometric center of the limit block 2. The limit block 2 is provided with a limit slot 4 matched with the slider 3. The slider 3 is slidingly installed in the limit slot 4. The limit slot 4 is mainly used for matching the movement of the slider 3, so that the movement path of the slider 3 can be better limited, thereby adapting to the control of the position coordinates of the slider 3, and the relative coordinates of the slider 3 on the limit block 2 are adjusted relatively. Even if the bearing seat 1 can be rotated at a necessary stage, the distance between the sliders 3 can also be adjusted relatively as long as a reference point is selected.

[0024] At least two sliders 3 are symmetrically arranged with the geometric center of the limit block 2. When the sliders 3 are used for load transmission, on the one hand, the load capacity can be uniformly transmitted, and on the other hand, when the number of sliders 3 is 4 or 6, multi-point support can be formed.

[0025] The limiting groove 4 extends from the outer side of the limiting block 2 to the center point of the limiting block 2, the sliding block 3 is provided with a mounting hole 5, and the mounting hole 5 is used for mounting the limiting column 6.

[0026] The driving mechanism is connected with the sliding block 3, the sliding block 3 is driven by the driving mechanism to move on the limiting block 2, so that the limiting column 6 contacts the rod-shaped part and restricts the movement stroke.

[0027] The driving mechanism can be a stroke cylinder or an electric control telescopic rod of an existing specification, and the type selection can be adaptively selected according to the size and pressure. The use of the driving mechanism can improve the tediousness of manually adjusting the sliding block 3. The sliding block 3 is driven by the driving mechanism to move in a fixed position, so that the limiting column 6 on the sliding block 3 moves in a specified area. The rod-shaped part is contacted and the posture of the rod-shaped part is restricted by the two or more limiting columns 6. Referring to the fact that the sliding block 3 has a fixed path on the limiting block 2, the sliding block 3 can be effectively restored by position adjustment after the angle of the rod-shaped part entering the bending machine is adjusted for many times.

[0028] Based on the above embodiment, reference is made to Figure 1 and Figure 2 Another embodiment of the utility model is that the driving mechanism includes a limiting ring 7 and a lead screw mechanism, the limiting ring 7 is sleeved on the outer wall of the limiting block 2, the limiting ring 7 is provided with a mounting port 701 corresponding to the limiting groove 4, and the lead screw mechanism is installed on the mounting port 701 and connected with the sliding block 3.

[0029] The limiting ring 7 is sleeved on the outer wall of the limiting block 2, the upper end of the limiting ring 7 has a height difference with the upper end of the limiting block 2, and the height of the limiting ring 7 is usually greater than the height of the limiting block 2, so as to ensure that the mounting port 701 is arranged on the limiting ring 7, and the height difference helps the limiting ring 7 to abut against the sliding block 3, so as to avoid that the stroke of the sliding block 3 exceeds the preset range. The load upper limit of the structure is increased by the contact surface between the limiting ring 7 and the sliding block 3.

[0030] Further, the mounting port 701 penetrates the side wall of the limiting ring 7, and the penetrating mode facilitates the lead screw mechanism to pass through the limiting ring 7 and act on the sliding block 3. The lead screw mechanism includes a lead screw 801 and a ball sleeve 802, the ball sleeve 802 is sleeved on the lead screw 801, the lead screw 801 rotates relative to the ball sleeve 802 to better move, the ball sleeve 802 is fixed in the mounting port 701, the ball sleeve 802 forms a mounting reference, and the lead screw 801 passes through the ball sleeve 802 and is connected with the limiting block 2. The lead screw 801 moves forward and backward on the ball sleeve 802 and drives the sliding block 3 to move.

[0031] It should be noted that if the ball sleeve 802 is rotated to move the lead screw 801 only back and forth, then the ball sleeve 802 needs to be fixed to the mounting port 701 via an existing mounting base. The selected ball sleeve 802 can be one with a mounting base, meaning that while the ball sleeve 802 is fixed by the mounting base, the ball units on the mounting base of the ball sleeve 802 are also allowed to rotate. In this method, the mounting base of the ball sleeve 802 is fixed to the mounting port 701. Provided that the lead screw 801 passes through the mounting port 701, the lead screw 801 can be positioned, and the ball sleeve 802 can rotate to move the lead screw 801.

[0032] refer to Figure 3 As shown, in a further embodiment, to prevent the lead screw 801 from rotating and causing abnormality in the slider 3 when it engages with the ball sleeve 802, the rear end of the slider 3 is provided with a socket containing a bearing. The outer ring of the bearing 9 is fixed in the socket, and the inner ring of the bearing 9 is connected to the lead screw 801. The outer diameter of the bearing 9 is matched with the inner diameter of the socket of the slider 3. The bearing 9 is welded to the slider 3, and the lead screw 801 is inserted into the inner ring of the bearing 9 and fixed, causing the lead screw 801 to rotate axially. The force transmitted by the rotation is consumed by the bearing 9 and does not act on the slider 3. The slider 3 is only affected by the thrust or pull force of its forward and backward movement.

[0033] In this method, the ball bearing sleeve 802 described in the above embodiment can be used for fixing and rotation. Alternatively, a non-rotating ball bearing sleeve 802 can be used, which can be directly fixed to the mounting port 701, and the slider 3 can be moved directly by rotating the lead screw 801.

[0034] Based on the above embodiments, another embodiment of this utility model is, with reference to Figure 3 As shown, the slider 3 includes a support portion 301 and an extension portion 302. The lower end of the support portion 301 is placed in the limiting groove 4, and the rear end of the support portion 301 is connected to the drive mechanism. The support portion 301 ensures the limiting of the slider 3 in the groove and ensures the load transmission from the drive mechanism to the slider 3. The extension portion 302 is placed on the upper end of the support portion 301, and the mounting hole 5 is provided in the extension portion 302. The extension portions 302 of two adjacent sliders 3 are placed at the same horizontal height. The same horizontal height facilitates the formation of a horizontal reference by the limiting post 6. The limiting post 6 passes through the mounting hole 5. In order to better install the limiting post 6 on the extension portion 302, the extension portion 302 and the support portion 301 form an L-shaped cross-sectional profile, so that the limiting post 6 can directly pass through the extension portion 302 in a vertical state.

[0035] A further implementation method is to refer to Figure 2 and Figure 4As shown, in order to better adapt to different sizes of rod-shaped parts and make the limiting post 6 replaceable and adjustable, the limiting post 6 includes an inner post 601 and an outer roller 602. The outer roller 602 is sleeved on the inner post 601. The length of the inner post 601 is greater than the length of the outer roller 602, so that the length of the outer roller 602 will not completely cover the inner post 601, so as to ensure that the lower end of the inner post 601 can be connected to the mounting hole 5 on the extension part 302.

[0036] The inner column 601 and outer roller 602 of the limiting column 6 can be sleeved together and fixed by pins or locks. This allows the outer roller 602 to be detachably mounted on the inner column 601.

[0037] In principle, the inner diameter of the outer roller 602 should match the outer diameter of the inner column 601. The outer diameter of the outer roller 602 can have various specifications, and its material can be existing polycarbonate or an alloy. (Reference) Figure 4 As shown, it should be noted that outer rollers 602 of different sizes can be fitted on the inner column 601 of the limiting column 6 to meet different collaborative clamping and auxiliary requirements of the limiting column 6.

[0038] The mounting hole 5 is provided with an internal thread, and the lower end of the inner post 601 is provided with an external thread. The inner post 601 is threadedly connected to the mounting hole 5, so that the inner post 601 and the mounting hole 5 can be disassembled as needed to install limit posts 6 of different limiting sizes.

[0039] A further embodiment involves providing at least two nuts on the inner column 601 to enhance its stability within the mounting hole 5. These nuts are fitted onto the inner column 601 and abut against the top and bottom of the extension portion 302, respectively. By providing a nut at each of the top and bottom of the inner column 601, the nuts effectively clamp the extension portion 302, preventing accidental movement of the inner column 601 within the mounting hole 5. Furthermore, by providing nuts at both ends of the inner column, the locking force of the nuts allows the load borne by the limiting post 6 to be transmitted to the slider 3 through the inner column. The method of locking the inner column 601 with nuts also facilitates fine-tuning or disassembly of the inner column 601.

[0040] Based on the above embodiments, another embodiment of this utility model is that the limiting block 2 is provided with a scale, which is located on one side of the limiting groove 4. The scale allows for a more intuitive determination of the position of the limiting block 2 within the limiting groove 4. Furthermore, the bearing seat 1 is provided with positioning holes 101 around its perimeter. These positioning holes 101 are used to fix the bearing seat 1 to the input side of the bending machine using bolts. There are multiple positioning holes 101, with equal spacing between adjacent holes 101. The structure of the positioning holes 101 facilitates the fixing of the bearing seat 1 to the work platform or load-bearing equipment, ensuring that the position of the limiting block 2 corresponds to the input side of the bending machine. This ensures the stability of the bearing seat 1 when bolted to the input side of the bending machine, preventing accidental movement under load.
