DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1: Reference Figure 1-5 A hydraulic fixing device for machining a hole in a steering knuckle is shown, comprising a base 1 and a pressing assembly 2. The base 1 is a U-shaped member, and two groups of clamping members 3 are installed at the notch 101 thereof. Both groups of clamping members 3 are of Z-shaped structure, and an installation bin 103 is provided inside the base 1. A driving mechanism and an adjusting mechanism are provided in the installation bin 103. The driving mechanism provides power for the entire device, and the adjusting mechanism is used to adjust the distance between the clamping members 3. The pressing assembly 2 functions to press the top of the workpiece after placing it on the clamping member 3 to prevent it from being driven during the working process of the broaching machine, resulting in errors in the processing of the workpiece.

[0024] The installation bin 103 is connected to the notch 101 via a through hole 104 , and the installation bin 103 is U-shaped, and a set of driving mechanisms and two sets of left-right symmetrical adjustment mechanisms are arranged inside the installation bin 103 , and the adjustment mechanisms are connected to the clamping member 3 via the protruding through hole 104 .

[0025] In order to stabilize the clamping members 3 during use, two groups of guide members 31 are provided at the bottom of each group of clamping members 3, and guide holes 102 adapted to the guide members 31 are provided on the opposite side of the notch 101. During the process of adjusting the spacing of the clamping members 3, the guide members 31 move in the guide holes 102, which plays an auxiliary role and strengthens the strength of each group of clamping members 3.

[0026] Adjustment mechanism: In order to stably drive the clamping parts 3 to move at a uniform speed, an adjusting rod 4 is rotatably connected to the opposite side of each group of clamping parts 3. The adjusting rod 4 is cross-shaped, and a thread is provided on its outer wall to mesh with the thread in the through hole 104. Therefore, when the adjusting rod 4 is rotated, the guide part 31 and the guide hole 102 cooperate with each other to prevent the clamping parts from rotating with the adjusting rod under the drive of inertia. The rotating adjusting rod 4 controls the distance between the two groups of clamping parts 3. An adjusting wheel 5 is rotatably connected to the position of the mounting bin 103 (the position of the through hole 104). The cross hole provided in the middle of the adjusting wheel 5 cooperates with the adjusting rod 4 (the adjusting wheel 5 here acts as a limiting tool). The adjusting wheel 5 cooperates with the synchronous wheel 7 provided on the mounting plate through the transmission belt 6. When the driving mechanism drives the synchronous wheel 7 to rotate, the adjusting rod 4 is controlled to rotate and the distance between the two groups of clamping parts 3 in the notch 101 is adjusted.

[0027] Driving mechanism: In order to enable a set of motors 11 to drive two sets of adjustment mechanisms to rotate, a set of worm gears 9 are rotatably connected to the two symmetrically arranged mounting plates. The threaded sections of the two sets of worm gears 9 rotate in opposite directions. The two sets of worm gears 9 are connected by a transmission rod 10. The motor 11 is connected to the transmission rod 10 through a gear set 12 (the gear set 12 is a bevel gear set, so as to achieve the purpose of the motor 11 driving the transmission rod 10), and then the motor 11 achieves the purpose of driving the two sets of worm gears 9 to rotate. In order to transmit the power of the rotation of the worm gears 9 to the synchronous wheel 7, each set of synchronous wheels 7 is provided with a worm wheel 8 coaxial therewith, and the worm wheel 8 and the worm gear 9 are meshed with each other, so as to achieve the purpose of power transmission of the driving mechanism. Through the cooperation of the above-mentioned structure and the threaded connection between the through hole and the adjusting rod 4, linear adjustment is achieved, so that this design scheme can be adapted to a variety of workpieces of different specifications.

[0028] In order to avoid a gap between the workpiece and the inner wall of the notch 101 when the workpiece is placed, a mounting hole 105 is provided on the inner wall of the notch 101, and auxiliary blocks of different thicknesses can be installed by bolts.

[0029] A groove may be provided on the opposite surface of the clamping member 3 or at the bottom transverse plate to play a positioning role during use.

[0030] The practical working principle of the present invention is as follows: according to the specifications of the workpiece, the motor 11 in the mounting chamber 103 of the base 1 is started, the driving shaft of the motor 11 rotates, and the transmission rod 10 is driven to rotate through the gear set 12. The rotating transmission rod 10 drives the worm 9 coaxial therewith to rotate on the mounting plate, and then drives the worm wheel 8 meshing therewith to rotate. The rotating worm wheel 8 drives the adjusting wheel 5 to rotate in the mounting chamber 103 through the synchronous wheel 7 coaxially arranged therewith (the self-locking property of the worm wheel 8 and the worm 9 is used to achieve structural fixation to avoid shaking during processing). The synchronous wheel 7 drives the adjusting wheel 5 to rotate in the mounting chamber 103 through the transmission belt 6. Under the cooperation of the cross hole and the adjusting rod 4, the adjusting rod 4 rotates in the through hole 104, and cooperates with the guide member 31 at the bottom of the clamping member 3. The guide member 31 moves in the guide hole 102, thereby adjusting the distance between the two groups of clamping members 3 in the notch 101. Subsequently, the workpiece is placed on the clamping member 3, and the pressing assembly 2 is started to fix the workpiece, and then the workpiece is processed by the broach.
