Description

Technical Field

[0001] This utility model relates to the field of bolt grooving technology, specifically to a grooving device for bolt heads. Background Technology

[0002] In existing technologies, some bolts require a slot to be cut into the surface of the bolt head to accommodate a wider variety of tools for tightening. Bolt production is typically automated on assembly lines, but for small-scale manufacturers with low production volumes, purchasing and operating automated lines is costly and does not meet their production needs. Therefore, a simple, low-cost semi-automatic slotting device is required. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] A grooving device for bolt heads includes: a clamping and fixing mechanism, a grooving mechanism, a longitudinal moving mechanism, and a transverse moving mechanism.

[0020] The clamping and fixing mechanism is used to clamp bolts, including an upper clamping block 1 and a lower clamping block. A guide structure is provided between the upper clamping block 1 and the lower clamping block. The upper clamping block 1 is connected to a first cylinder 3 to drive the lifting and lowering. The lower end of the upper clamping block 1 is provided with an upper arc groove, and the upper end of the lower clamping block is provided with a lower arc groove. The upper arc groove and the lower arc groove correspond to each other.

[0021] The grooving mechanism is used to groove the bolt head 13, and includes a first motor 11. The output end of the first motor 11 is connected to a grooving cutter 12 facing between the upper clamping block 1 and the lower clamping block.

[0022] The longitudinal moving mechanism is used to drive the first motor 11 to move along the direction of the slot.

[0023] The lateral movement mechanism is used to drive the first motor 11 to drive the grooving cutter 12 to penetrate the bolt head 13. The lateral movement mechanism is located at the upper end of the longitudinal movement mechanism, and the first motor 11 is installed at the upper end of the lateral mechanism.

[0024] The bolt's thread is clamped between the upper clamping block 1 and the lower clamping block, with the bolt head 13 protruding towards the first motor 11. The first motor 11 drives the grooving cutter 12 to rotate at high speed, and under the action of the longitudinal and transverse moving mechanisms, it grooves the bolt head 13. The structure is simple, the operating cost is low, and maintenance is convenient.

[0025] In a preferred embodiment, the guide structure includes four guide rods 2 fixedly mounted on the lower clamping block, and the upper clamping block 1 has four guide holes that mate with the guide rods 2 one by one.

[0026] In a preferred embodiment, the lower clamping block is provided with a magnet located at the bottom of the lower arc groove.

[0027] Since the upper clamping block 1 and the lower clamping block clamp the bolt, if the force is too great, the threads on the bolt will deform and be damaged. If the force is too small, the bolt will easily rotate when slotting. Therefore, by setting a magnet, the bolt is firmly attracted to the lower clamping block, and with the clamping of the upper clamping block 1, the bolt is prevented from rotating.

[0028] In a preferred embodiment, the longitudinal moving mechanism includes a first track and a first sliding plate 5 mounted on the first track and sliding on the first track. The first sliding plate 5 is driven by a lead screw mechanism 6, which is connected to a second motor 7.

[0029] In a preferred embodiment, the lateral movement mechanism includes a second track and a second slide plate 9 mounted on the second track and sliding on the second track. The second slide plate 9 is driven to move by a second cylinder 10. The second track is mounted on a longitudinal movement mechanism, and the first motor 11 is mounted on the second slide plate 9.
