When changing different models of workpieces for machining, different clamping toolings need to be frequently disassembled and assembled, which is time-consuming and costly to manufacture. Therefore, it is necessary to manufacture a horizontal machining clamping tool to solve the above problems. SUMMARY

[0006] Further description of the utility model: the middle part of the support base plate is provided with a positioning circular hole vertically penetrating the support base plate.

[0007] Further description of the utility model: the outer end of the clamping part is fixed to the upper end of the connecting part, the inner end of the clamping part is provided with a contact boss below, and the contact boss is provided with a rounded corner below.

[0008] Further description of the utility model: the rear end of the support base plate is provided with a positioning through hole vertically penetrating the support base plate.

[0009] Further description of the utility model: the front end of the support base plate is provided with a clearance inclined surface on the lower side, the clearance inclined surface is inclined upward towards the front side, and the clearance inclined surface has an overlapping part with the bottom of the screw hole.

[0010] The beneficial effects of this utility model are as follows: For workpieces with vertical deep holes (i.e., deep holes without an inclination angle), the workpiece is placed above the support base plate. Then, the gripper assembly is assembled, with the sliding part corresponding to the groove and the clamping part corresponding to the position above the boss on the workpiece. The locking screw is screwed into the sliding part and continuously screwed in, so that the locking screw presses against the groove. At the same time, the clamping part presses down on the boss on the workpiece, thereby completing the fixation of the workpiece. Through the groove, the gripper assembly can adapt to workpieces with different outer diameters for clamping. For machining deep holes with a certain inclination angle, an adjusting screw can be added, so that the adjusting screw protrudes upward from the upper end face of the support base plate, thereby tilting the workpiece at a certain angle before clamping. By adjusting the height of the protruding upper end of the adjusting screw, the inclination angle of the workpiece can be flexibly adjusted to machine deep holes with different inclination angles. The advantages of this design are: it can simultaneously accommodate deep hole machining workpieces with and without tilt angles, and the placement angle of the workpiece can be flexibly adjusted to machine deep holes with different tilt angles on the workpiece, thereby improving the versatility and flexibility of the clamping fixture and reducing the manufacturing cost of the clamping fixture.

The clamping jaw assembly 02 includes a sliding part 021, a connecting part 022 and a clamping part 023 which are integrally arranged. The inner end of the sliding part 021 corresponds to the inside of the sliding groove 011, and the outer end corresponds to the outside of the sliding groove 011. The lower end of the connecting part 022 is fixed to the outside of the sliding part 021. The clamping part 023 is fixed to the upper end of the connecting part 022. The width of the sliding part 021 is smaller than the width of the sliding groove 011. The locking screw 03 is threadedly connected with the sliding part 021 and the upper end thereof is in abutment with the sliding groove 011. The clamping jaw assembly 02 is provided with two groups and corresponds to the left and right sides of the support base plate 01. The front end of the support base plate 01 is vertically provided with a screw hole 012. The upper end of the adjusting screw 04 is provided with a thread and is threadedly connected with the screw hole 012.

[0019] For machining a vertical deep hole of a workpiece, i.e. the deep hole has no inclination angle, the workpiece is placed above the support base plate 01. Then, the clamping jaw assembly 02 is assembled. The sliding part 021 corresponds to the inside of the sliding groove 011, and the clamping part 023 corresponds to the position above the boss of the workpiece. The locking screw 03 is screwed into the sliding part 021, and the locking screw 03 is continuously screwed in to press the locking screw 03 against the sliding groove 011, and at the same time, the clamping part 023 is pressed downward against the boss on the workpiece, thereby completing the fixation of the workpiece.
