Description

Technical Field

[0001] This utility model relates to the field of mounting components, and in particular to a mounting plate for a bolt cold heading machine fixing fixture. Background Technology

[0002] Cold heading machines are specialized equipment primarily used for the mass production of fasteners such as nuts and bolts.

[0003] When a fixture is fixedly connected to a mounting plate, a screw and nut connection is generally used. The screw is screwed into the screw hole, and the nut is connected to the bottom end of the screw, with the top end of the nut pressing against the surface of the mounting plate to fix the fixture. The top ends of the screw and nut can be sealed with washers to seal the gaps between the screw top and the screw hole, and between the nut top and the mounting plate. However, it is not convenient to install washers at the connection between the bottom end of the screw and the nut, leaving the connection exposed to the outside environment. This makes it easy for external water vapor to enter, leading to corrosion of the screw. Therefore, a mounting plate for fixing fixtures in bolt cold heading machines is needed to seal and block the connection between the bottom end of the screw sidewall and the nut. Utility Model Content

[0004] The purpose of this utility model is to overcome the defect that the connection between the bottom end of the screw sidewall and the nut is inconvenient to seal, and to provide a mounting plate for a bolt cold heading machine fixing fixture.

[0005] The technical solution to achieve the above objective is: a mounting plate for a bolt cold heading machine fixing fixture, comprising a fixture body and a mounting plate body. Multiple mounting screw holes are provided on the side walls of both the fixture body and the mounting plate body. Mounting screws are threaded into the mounting screw holes. A mounting nut is threaded to the bottom end of the side wall of each mounting screw. A first washer is connected to the top side wall of each mounting screw. A support mechanism is provided at the bottom end of the mounting plate body, and a sealing mechanism is provided within the support mechanism. A connecting screw hole is provided at the bottom end of the mounting plate body.

[0006] Preferably, the connection between the fixture body and the mounting plate body is located between the mounting screw and the mounting nut.

[0007] Preferably, the first washer is located between the tip of the mounting screw and the fixture body.

[0008] Preferably, the mounting screw hole is located at the inner center of the connecting screw hole.

[0009] Preferably, the support mechanism includes a connecting screw tube, a supporting screw tube, a connecting ring, a second washer, a cap, and an inner screw rod. The connecting screw tube is threaded to the side wall of the connecting screw hole, the supporting screw tube is connected to the bottom end of the connecting screw tube, the connecting ring is connected to the top side wall of the supporting screw tube, the second washer is connected to the side wall of the connecting ring, the inner screw rod is threaded to the inner side wall of the supporting screw tube, and the cap is connected to the bottom end of the inner screw rod.

[0010] Preferably, the diameter of the inner screw is smaller than the diameter of the cap, the cap is cylindrical, a sealing gasket is fitted on the inner sidewall of the cap, the threaded groove of the supporting screw is located on the inner sidewall of the supporting screw, and the threaded groove of the connecting screw is located on the outer sidewall of the connecting screw.

[0011] Preferably, the sealing mechanism includes a support plate, a through hole, a rubber pad, and a torsion ring. The inner side wall of the support tube is threaded with the support plate, the side wall of the support plate has a through hole, the side wall of the through hole and the top side wall of the support plate are both connected with rubber pads, and the bottom side wall of the support plate is connected with a torsion ring.

[0012] Preferably, the rubber pad is T-shaped.

[0013] The beneficial effects of this utility model are:

[0014] 1) Place the support plate into the support screw tube, rotate the torsion ring to screw the support plate into the support screw tube, and move the through hole and rubber pad. The rubber pad is tightly attached to the connection between the mounting nut and the mounting screw. Utilizing the elasticity of the rubber pad, even if the bottom end of the mounting nut is not flush with the bottom end of the mounting screw, the mounting screw will press down on the rubber pad when the rubber pad contacts the mounting screw, causing the rubber pad to deform and protrude downwards from the rubber pad in the through hole. The rubber pad at the upper end of the support plate will be tightly attached to the connection between the mounting nut and the mounting screw, thereby achieving the effect of conveniently sealing the connection between the mounting nut and the mounting screw.

[0015] 2) Then screw the inner screw into the support screw tube so that the cap covers the bottom end of the support screw tube. The cylindrical shape of the cap and the sealing gasket seal the bottom opening of the support screw tube, so that the support screw tube wraps around the connection between the mounting nut and the mounting screw, achieving a multi-layer sealing effect at the connection between the mounting nut and the mounting screw.

[0027] Screw the mounting screw 4 into the mounting screw hole 3, and place the first washer 5 under the top of the mounting screw 4 so that the mounting screw 4 can press the first washer 5 onto the fixture body 1. Screw the mounting nut 9 onto the bottom end of the mounting screw 4, and place the first washer 5 on the top end of the mounting nut 9 so that the mounting nut 9 presses the first washer 5 onto the mounting plate body 2, thereby fixing the fixture body 1 and the mounting plate body 2.

[0028] Reference Appendix Figure 3-6 The support mechanism 7 includes a connecting screw tube 701, a support screw tube 702, a connecting ring 703, a second washer 704, a cover 705, and an inner screw rod 706. The connecting screw tube 701 is threaded to the side wall of the connecting screw hole 6. The support screw tube 702 is connected to the bottom end of the connecting screw tube 701. The connecting ring 703 is connected to the top side wall of the support screw tube 702. The second washer 704 is connected to the side wall of the connecting ring 703. The inner screw rod 706 is threaded to the inner side wall of the support screw tube 702. The cover 705 is connected to the bottom end of the inner screw rod 706. The diameter of the inner screw rod 706 is smaller than the diameter of the cover 705. The cover 705 is cylindrical in shape. A sealing gasket is fitted on the inner side wall of the cover 705. The threaded groove of the support screw tube 702 is located on the inner side wall of the support screw tube 702. The threaded groove of the connecting screw tube 701 is located on the outer side wall of the connecting screw tube 701.

[0029] Reference Appendix Figure 4-6 The sealing mechanism 8 includes a support plate 801, a through hole 802, a rubber pad 803, and a torsion ring 804. The inner side wall of the support screw tube 702 is threaded with the support plate 801. The side wall of the support plate 801 has a through hole 802. The side wall of the through hole 802 and the top side wall of the support plate 801 are both connected with rubber pads 803. The bottom side wall of the support plate 801 is connected with a torsion ring 804. The rubber pad 803 is T-shaped.

[0030] Screw the connecting screw tube 701 into the connecting screw hole 6, so that the mounting screw 4 and the mounting nut 9 are located inside the supporting screw tube 702. The connecting screw tube 701 drives the supporting screw tube 702 to move upward, so that the connecting ring 703 also moves upward, thereby causing the connecting ring 703 to drive the second washer 704 to press against the bottom end of the mounting plate body 2, thereby sealing the connection between the connecting screw hole 6 and the connecting screw tube 701. Then, rotate and unscrew the cover 705, and unscrew the cover 705 and the inner screw rod 706. When the support mechanism 7 is not needed, simply unscrew the connecting screw tube 701 from the connecting screw hole 6 for easy disassembly.

[0031] At this point, the support plate 801 is placed into the support screw tube 702, and the torsion ring 804 is rotated to screw the support plate 801 into the support screw tube 702. This causes the support plate 801 to move the through hole 802 and the rubber pad 803. The rubber pad 803 is tightly attached to the connection between the mounting nut 9 and the mounting screw 4. Utilizing the elasticity of the rubber pad 803, even if the bottom end of the mounting nut 9 is not flush with the bottom end of the mounting screw 4, when the rubber pad 803 contacts the mounting screw 4, the mounting screw 4 will press down on the rubber pad 803, causing the rubber pad 803 to deform. This allows the rubber pad 803 located in the through hole 802 to move. 03 protrudes downwards, and the rubber pad 803 located at the upper end of the support plate 801 will fit tightly against the connection between the mounting nut 9 and the mounting screw 4, thereby achieving the effect of conveniently sealing the connection between the mounting nut 9 and the mounting screw 4. At this time, the inner screw 706 is screwed into the support screw tube 702, so that the cover 705 covers the bottom end of the support screw tube 702. The cylindrical shape of the cover 705 and the sealing gasket are used to seal the bottom opening of the support screw tube 702, so that the support screw tube 702 wraps around the connection between the mounting nut 9 and the mounting screw 4, achieving a multi-layer sealing effect at the connection between the mounting nut 9 and the mounting screw 4.
