[0049] A drilling device for universal joint production with an offset correction function solves the technical problem in the related art that the downward force of the drill bit will cause the rotating part to be compressed and deformed, the position to be offset, and the concentricity of the two rotating holes to be relatively poor, and the processing accuracy to be relatively low. It can position the universal joint component, correct the offset, and the rotating part on the universal joint component will not be compressed and deformed, and the concentricity of the rotating hole is relatively good, which ensures the positive effect of processing accuracy. The overall idea is as follows:

[0050] Implementation method 1: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig.16As shown; a drilling device for universal joint production with an offset correction function, comprising: a drilling machine 10; and also comprising: at least one elastic stopper 20, connected to the workbench of the drilling machine 10, for limiting the universal joint component 100, and the drill bit 11 on the drilling machine 10 drills the rotating hole 101 on the universal joint component 100;

[0051] The elastic limiting member 20 comprises: a lower seat 21, which is arranged on the workbench;

[0052] A combined upper support 22, one end of which is connected to the top of the lower seat body 21, and a spacing space 23 is formed between the combined upper support 22 and the lower seat body 21. The combined upper support 22 has a first through slot 221 and a second through slot 222, and the first through slot 221 and the second through slot 222 are spaced apart from each other;

[0053] A first spring 24, disposed at the first through slot 221, and spaced apart from the first through slot 221;

[0054] A second spring 25 is disposed at the second through slot 222 and spaced apart from the second through slot 222 , wherein the tension of the first spring 24 is greater than the tension of the second spring 25 ;

[0055] Two rotatable inner support members 26 are symmetrically connected to the combined upper support 22 and spaced apart from the lower seat body 21. One end of the rotatable inner support member 26 is connected to the first spring 24, and the other end is connected to the second spring 25. The rotatable inner support member 26 is used to be arranged between the rotating parts 102 on the universal joint component 100 together with the combined upper support 22 to support the rotating parts 102.

[0056] A first side support 27, connected to the other end of the combined upper support 22 and connected to the lower seat 21, for supporting and limiting the connecting portion 103 on the universal joint component 100;

[0057] and two second side supports 28, symmetrically connected to the combined upper support 22, arranged opposite to the first side supports 27, and used for supporting and limiting the side walls of the rotating part 102;

[0058] Specifically, during implementation, an elastic stopper 20 is provided; the elastic stopper 20 comprises: a lower seat 21, a combined upper support 22, a first spring 24, a second spring 25, a rotatable inner support 26, a first side support 27 and a second side support 28;

As the universal joint component 100 moves, the rotatable inner support member 26 is squeezed and rotated by the rotating portion 102, the first spring 24 is stretched, and the second spring 25 is compressed until the rotatable inner support member 26 is rotated. The support member 26 partially fits the combined upper support 22, and the rotating part 102 fits with the rotatable inner support member 26, and is supported from the inside to the outside by the rotatable inner support member 26 and the combined upper support 22, so that the position of the universal joint component 100 is corrected, and the universal joint component 100 is positioned. The drill bit 11 on the drilling machine 10 drills the rotating hole 101 on the universal joint component 100, so that the rotating part 102 will not be compressed and deformed, and will not be displaced. The concentricity of the rotating hole 101 after forming is relatively good, which ensures the processing accuracy.

[0060] Implementation method 2: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown; during implementation, the lower seat body 21 includes: an L-shaped bending member 21-1, which is arranged on the workbench; and two first reinforcing plates 21-2, which are connected to the bending part of the L-shaped bending member 21-1;

[0061] The L-shaped bending member 21-1 is formed by bending a plate and is pressed on a workbench by bolts to form a reliable supporting structure;

[0062] The first reinforcing plate 21 - 2 is a triangular plate structure and is welded to the L-shaped bending part 21 - 1 to improve the structural strength.

[0063] Implementation method 3: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8As shown; when implemented, the combined upper support 22 includes: a side connecting plate 22-1, connected to the top of the lower seat body 21; a support body 22-2, connected to one side wall of the side connecting plate 22-1, one end of the support body 22-2 has a first arc groove 22-21, the other end has a second arc groove 22-22, and the middle position has a first through hole 22-23, the first through hole 22-23 is passed through by the drill bit 11, the diameter of the first through hole 22-23 is larger than the diameter of the rotating hole 101 after molding, and two arc surfaces 22-24 are symmetrically arranged on the support body 22-2, The arc surface 22-24 is close to the first through hole 22-23; a first end surface stopper 22-3, connected to one end of the support body 22-2, the first end surface stopper 22-3 has a third arc groove 22-31, the third arc groove 22-31 and the first arc groove 22-21 together form the first through groove 221; and a second end surface stopper 22-4, connected to the other end of the support body 22-2, the second end surface stopper 22-4 has a fourth arc groove 22-41, the fourth arc groove 22-41 and the second arc groove 22-22 together form the second through groove 222;

[0064] The side connecting plate 22-1 is a square plate structure, connected to the lower seat body 21 by bolts, and is easy to install and disassemble;

[0065] The support body 22-2 is welded to the side connecting plate 22-1. After being projected from the plane in the direction of the side connecting plate 22-1, the shape of the support body 22-2 is roughly a "convex" structure, forming a step. The step is conducive to setting the arc surface 22-24 and facilitating the smooth rotation of the rotatable inner support member 26 without collision. The long plate 26-61 and the short plate 26-62 on the bent inner support plate 26-6 can contact and fit with the support body 22-2 respectively as they rotate. When the long plate 26-61 fits with the support body 22-2, the bent inner support plate 26-6 supports the rotating part 102. When the universal joint component 100 is removed or not installed, the short plate 26-62 fits with the support body 22-2, and the flexibility of use is good.

[0066] A first arc-shaped groove 22-21 is provided, which together with the third arc-shaped groove 22-31 forms a first through groove 221, which is conducive to accommodating the first spring 24, does not affect the expansion and contraction of the first spring 24, and is relatively beautiful;

[0067] A second arc-shaped groove 22-22 is provided, which together with the fourth arc-shaped groove 22-41 forms a second through groove 222, which is conducive to accommodating the second spring 25, does not affect the expansion and contraction of the second spring 25, and is relatively beautiful;

[0068] A first through hole 22-23 is provided, and the diameter of the first through hole 22-23 is larger than the diameter of the rotation hole 101 after forming. When the drill bit 11 forms the rotation hole 101, it will not collide with the drill bit 11, and the structural reliability is relatively good;

[0069] The arc-shaped surfaces 22-24 are provided to facilitate the smooth rotation of the rotatable inner support member 26 without causing collision;

[0070] The first end surface stopper 22-3 is roughly a square structure, and is connected to the support body 22-2 by bolts to form a block to protect the first spring 24, and the structural reliability is relatively good;

[0071] The second end surface stopper 22-4 is roughly a square structure, and is connected to the support body 22-2 by bolts to form a block to protect the second spring 25, and the structural reliability is relatively good;

[0072] A combined upper support 22 is provided to form a reliable support structure, which is conducive to connecting and arranging other components.

[0073] Implementation 4: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown; during implementation, a spacing space 23 is provided, when the drill bit 11 forms the rotating hole 101, the drill bit 11 will not collide with the lower seat body 21, and the metal chips generated by drilling can be discharged into the spacing space 23, and cleaning is relatively convenient.

[0074] Implementation 5: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Fig.16 As shown; during implementation, the first spring 24 or the second spring 25 is a cylindrical spring;

[0075] When the rotating part 102 is positioned between the bent inner support plates 26-6, the first spring 24 is stretched and the second spring 25 returns to its original position. Since the pulling force of the first spring 24 is greater than the pulling force of the second spring 25, the bent inner support plate 26-6 can apply force toward the rotating part 102, thereby achieving the purpose of tightening the rotating part 102 internally.

[0076] When the rotating part 102 is removed from the bent inner support plate 26-6, since the tension of the first spring 24 is greater than the tension of the second spring 25, the first spring 24 returns to its original position, and the second spring 25 is stretched, so that the bent inner support plate 26-6 can rotate back to its original position;

[0077] The pulling force refers to the force generated when the spring returns to its original position. The pulling force of the first spring 24 is greater than the pulling force of the second spring 25, which is beneficial for the first spring 24 to rotate the bent inner support plate 26-6 when returning to its original position, stretch the second spring 25, and make the bent inner support plate 26-6 rotate back to its original position.

[0078] Implementation 6: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.16 As shown; when implemented, the rotatable inner support member 26 includes: two support seats 26-1, symmetrically connected to the support body 22-2; two bearings 26-2, one-to-one connected to the support seat 26-1; a shaft 26-3, connected between the bearings 26-2, and spaced apart from the arc surface 22-24; two cover plates 26-4, one-to-one connected to the support seat 26-1, surrounding the shaft 26-3, pressing the bearing 26-2; a bracket 26- 5, connected to the shaft 26-3, arranged between the support seats 26-1, and spaced apart from the arc-shaped surfaces 22-24; and a bent inner support plate 26-6, connected to the bracket 26-5, one end of which is connected to the first spring 24, and the other end of which is connected to the second spring 25, and rotates with the bracket 26-5 and the shaft 26-3 around the bearing 26-2 as the rotation center, and the bent inner support plate 26-6 is used to directly contact the rotating part 102;

[0079] The support seat 26-1 is a triangular plate-shaped structure, and is connected to the side wall of the support body 22-2 by bolts inserted therein, forming a reliable support structure;

[0080] The bearing 26-2 is a common structure in the prior art, such as a deep groove ball bearing, which is connected to the stepped through hole on the support seat 26-1, which is conducive to supporting the shaft 26-3, and the shaft 26-3 can rotate freely;

[0081] The shaft 26-3 is a stepped shaft connected between the bearings 26-2, which is convenient for connecting the bracket 26-5;

[0082] The cover plate 26-4 is a circular plate structure, which is sleeved on the shaft 26-3, and is spaced apart from the shaft 26-3. The cover plate 26-4 is connected to the support seat 26-1 by bolts, and presses the bearing 26-2 to prevent the bearing 26-2 from falling off.

[0084] The bent inner support plate 26-6 includes: a long plate 26-61, one end of which is connected to the second spring 25, and a second through hole 26-61-1 is provided in the middle, and the diameter of the second through hole 26-61-1 is larger than the diameter of the rotating hole 101 after molding; a short plate 26-62, which is connected to the other end of the long plate 26-61, and the angle A between the short plate 26-62 and the long plate 26-61 is 165°-170°, and the short plate 26-62 is connected to the support body 22-2 and the When the first end surface stopper 22-3 contacts, the short plate 26-62 is embedded in the inner groove 22-32 of the support body 22-2 and the first end surface stopper 22-3, and the upper surface of the short plate 26-62 is flush with the upper surfaces of the support body 22-2 and the first end surface stopper 22-3; and the baffle 26-63 is connected to the long plate 26-61, and when the long plate 26-61 supports the rotating part 102, the baffle 26-63 blocks and limits the rotating part 102;

[0085] The long plate 26-61 and the short plate 26-62 are formed by bending the plate, and the angle A between the long plate 26-61 and the short plate 26-62 is preferably 165°. The length of the long plate 26-61 is about five times the length of the short plate 26-62, which is conducive to the long plate 26-61 and the rotating part 102 to fit together and position the rotating part 102;

[0086] The baffle 26-63 is welded to the long plate 26-61 to block and limit the rotating part 102, which is relatively convenient to clamp and has relatively uniform precision;
