In order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model provides a purpose-made lathe presss from both sides tight piece fastening bolt, includes bolt head, bolt, purpose-made clamp piece, its characterized in that: the bolt head of the fastening bolt is an inner hexagon bolt head, the lower end of the bolt head is combined with a bolt with a limiting shoulder, the bolt below the limiting shoulder is provided with a thread, an overtravel groove is formed between the limiting shoulder and the thread below the limiting shoulder, the fastening bolt is matched with a specially-made clamping block for use, the bolt head of the fastening bolt is lower than the top surface of the specially-made clamping block, and the bolt head is combined with the top surface of the limiting shoulder of the bolt in a welding mode.
Furthermore, the limiting shoulder is designed with a certain fit clearance according to the size of the inner hole of the clamping block, and the fit clearance between the side wall of the inner hole and the outer wall of the limiting shoulder is ensured to be within the range of 0.4-0.8 mm.
Furthermore, a rectangular limiting groove is formed in the left side of the special clamping block, an acute-angle limiting groove is formed in the front end of the right side of the special clamping block, and an arc-shaped limiting groove is formed in the corresponding rear end of the right side of the special clamping block.
Furthermore, the middle part of the special clamping block is provided with a through hole with an inverted convex section.
The utility model discloses the beneficial effect who reaches is: the manufacturing method of the utility model can effectively shorten the period of manufacturing the fastening bolt, and the part is firmly and reliably clamped by matching with the special clamping block, and the clamping area is large; the special clamping block can adjust the direction of the workpiece to clamp when in use according to different shapes, so that the contact surface can be prevented from being damaged by clamping; the design of hexagon socket head cap and counter bore has made things convenient for the tight anchor clamps of fastening and has improved the security of adding man-hour, and the special side contact of pressing from both sides tight piece perpendicular working face and work piece makes the difficult condition that appears the displacement when the work piece adds man-hour.
