Description

Technical Field

[0001] The utility model relates to the technical field of nut fixtures, and particularly relates to a nut locking fixture. Background Art

[0002] A nut is a common threaded fastener. For example, a fixture for placing wafers used in the manufacture of optical lenses is provided with nuts. When using the wafers, the nuts on the fixture need to be removed to loosen the fixture.

[0003] At present, most of the nuts used have a hexagonal shape and are composed of upper and lower planes and threaded holes. Therefore, during the disassembly process, it is easy to slip and the stability is not high. When the fixture is running, it is difficult to quickly position and process the nuts. At the same time, during the processing of the nuts by the fixture, the chips generated by nut tapping will accumulate inside the fixture, which will affect the accuracy of the next batch of nut processing. Summary of the Invention

[0004] The purpose of the utility model is to provide a nut locking fixture to solve the above-mentioned defects in the prior art.

[0005] A nut locking fixture includes a device base. One side of the device base is connected with a side bracket. A fixture substrate is arranged directly above the device base. A limiting mechanism is arranged directly above the fixture substrate. The limiting mechanism limits and locks the top end of the nut to prevent the nut from shifting during tapping, and at the same time performs tapping treatment on multiple groups of nuts. One side of the fixture substrate is provided with an adjusting mechanism. The adjusting mechanism adjusts the height and position of the tapping equipment according to the number of nuts and processing requirements to improve the tapping treatment of nuts with different diameters.

[0006] Preferably, the limiting mechanism includes guiding slide rods, a transverse locking plate, drilling through holes, and an electric telescopic rod. The guiding slide rods are symmetrically distributed on both sides of the device base. The outside of the guiding slide rods is penetrated and connected with the transverse locking plate. The outside of the transverse locking plate is equidistantly provided with drilling through holes. One side of the transverse locking plate is connected with the output end of the electric telescopic rod. The electric telescopic rod is installed on one side of the fixture substrate. The bottom end of the side bracket is arranged directly above the transverse locking plate.

[0007] Preferably, the transverse locking plate is connected with the fixture substrate through the guiding slide rods arranged on both sides.

[0008] Preferably, the adjusting mechanism includes an electric cylinder, a horizontal support plate, a jig substrate, an internal groove, a motor, and a tapping screw rod. The electric cylinder is installed at the top of the side bracket. The output end of the electric cylinder is connected to a horizontal support plate. The bottom end of the horizontal support plate is connected to a motor. The output end of the motor is connected to a tapping screw rod.

[0009] Preferably, the motor is connected to the output end of the electric cylinder through the horizontally arranged support plate at the top.

[0010] Preferably, the bottom end of the jig substrate is equidistantly provided with material leakage holes.

[0011] Compared with the prior art, the present utility model has the following advantages:

[0012] 1. During use, by setting the horizontal locking plates with different diameters in the drilled through holes, and performing horizontal locking through the horizontally arranged "C"-shaped horizontal locking plates, thereby limiting the top end of the nut through the horizontal locking plate, avoiding the tapping screw rod from vertically processing the nut, preventing the nut from shifting during the processing, and improving the efficiency of batch processing of the nut.

[0021] To make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation manners.

[0022] As Figures 1 to 5 shown, a nut locking fixture includes a device base 1. A side bracket 6 is connected to one side of the device base 1. A fixture base plate 10 is arranged directly above the device base 1. A limiting mechanism 4 is arranged directly above the fixture base plate 10. The limiting mechanism 4 limits and locks the top end of the nut to prevent the nut from shifting during the tapping process, and at the same time performs tapping treatment on multiple groups of nuts. An adjusting mechanism 9 is arranged on one side of the fixture base plate 10. The adjusting mechanism 9 adjusts the height and position of the tapping equipment according to the number of nuts and processing requirements, so as to improve the tapping treatment of nuts with different diameters.

[0023] In this embodiment, the limiting mechanism 4 includes a guide slide bar 2, a lateral locking plate 3, a drilled through-hole 5 and an electric telescopic rod 13. The guide slide bars 2 are symmetrically distributed on both sides of the device base 1. The lateral locking plate 3 is connected through the outside of the guide slide bar 2. The outside of the lateral locking plate 3 is equidistantly provided with drilled through-holes 5. The output end of an electric telescopic rod 13 is connected to one side of the lateral locking plate 3. The electric telescopic rod 13 is installed on one side of the fixture base plate 10. The bottom end of the side bracket 6 is arranged directly above the lateral locking plate 3. The motor 14 is driven to displace by the electric telescopic rod 13 to complete the tapping treatment of multiple groups of nuts.

[0024] In this embodiment, the lateral locking plate 3 is connected to the fixture base plate 10 through the guide slide bars 2 arranged on both sides. The two sides of the lateral locking plate 3 are limited by the guide slide bars 2 to prevent the lateral locking plate 3 from shifting.

[0025] In this embodiment, the adjusting mechanism 9 includes an electric cylinder 7, a horizontal support plate 8, a fixture substrate 10, an internal groove 11, a motor 14, and a tapping screw rod 15. The electric cylinder 7 is installed at the top of the side bracket 6. The output end of the electric cylinder 7 is connected to a horizontal support plate 8. The bottom end of the horizontal support plate 8 is connected to a motor 14. The output end of the motor 14 is connected to a tapping screw rod 15. The outer side of the fixture substrate 10 is equally spaced with internal grooves 11. The horizontal support plate 8 is arranged below the side bracket 6. The fixture substrate 10 limits the nut through the internal grooves 11 provided at the top to prevent the nut from loosening.

[0026] In this embodiment, the motor 14 is connected to the output end of the electric cylinder 7 through the horizontal support plate 8 provided at the top, and the top of the nut is pressed against by the horizontal support plate 8 to prevent the nut from loosening during the processing.

[0027] In this embodiment, the bottom end of the fixture substrate 10 is equally spaced with material leakage holes 12. The debris generated during the processing is collected and discharged through the material leakage holes 12 to complete the cleaning of the nut debris.

[0028] When this nut locking fixture is actually applied, it includes the following working contents:

[0029] Step 1: The operator first selects the internal groove 11 with the corresponding diameter, directly places the nut into the internal groove 11, selects the diameter of the tapping screw rod 15 with the corresponding diameter, positions the diameter of the internal groove 11 and the drill through hole 5, and correspondingly installs the motor 14 and the tapping screw rod 15 directly above the drill through hole 5, so as to facilitate inserting the tapping screw rod 15 into the drill through hole 5.

[0030] Step 2: The operator turns on the electric telescopic rod 13, pushes one side of the horizontal locking plate 3 through the electric telescopic rod 13. The horizontal locking plate 3 slides horizontally through the guiding slide rod 2 provided on the outside, thereby adjusting the positions of the horizontal locking plate 3 and the side bracket 6. The top of the internal groove 11 provided at the top of the fixture substrate 10 is blocked by the horizontal locking plate 3 to prevent the nut from loosening. Then turn on the electric cylinder 7, and drive the horizontal support plate 8 to descend vertically through the electric cylinder 7, so that the tapping screw rod 15 contacts the top of the nut.

[0031] Step 3: The tapping screw rod 15 is used to perform a hole opening operation on the top of the nut, so that the material leakage holes 12 directly introduce the processed debris into the device base 1, which is convenient for the operator to take out the debris from the device base 1. When the drilling of the nut is completed, drive the horizontal support plate 8 and the motor 14 to rise vertically through the electric cylinder 7, so that the tapping screw rod 15 moves out of the internal groove 11.

[0032] Step 4: Subsequently, the electric telescopic rod 13 drives the side bracket 6 and the transverse support plate 8 to move to the other side. At the same time, the transverse locking plate 3 unlocks the top of the built-in groove 11 from the closed surface, and the operator directly takes out the tapped nut and then fills the untapped nut into the inside of the built-in groove 11.

[0033] Therefore, the above-disclosed embodiments are illustrative in all respects and not exclusive. All changes within the scope of the present utility model or within the scope equivalent to the present utility model are encompassed by the present utility model.
