Technical Field
[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a horizontal clamping pressure-holding fixture. Background Technology
[0002] When milling and drilling are required on castings, the castings must first be fixed before milling and drilling. Currently, castings are usually milled and drilled using a drilling and milling machine, but since the drilling and milling machine can only process one casting at a time, the processing efficiency is low.
[0003] In the existing technology, there is a hydraulic valve body 2. The valve body 2 has a first end face 21 and a second end face 22 that need to be machined. The first end face 21 and the second end face 22 are machined and drilled by a milling machine, respectively. The valve body 2 has a pressing surface 23 that abuts against the clamping mechanism. Therefore, the casting needs to be precisely positioned and fixed each time. If there is an error in the installation, it will lead to a decrease in machining accuracy. Moreover, only one casting can be machined at a time, resulting in low machining efficiency. Therefore, there is an urgent need to improve this shortcoming. Utility Model Content

[0025] In this application, there are two sets of the first clamping mechanism 3, and the two sets of the first clamping mechanism 3 are installed on the first busbar 13 along the height direction. Each of the first clamping mechanisms 3 includes a first mounting seat 31, a second mounting seat 32, a third mounting seat 33, a fourth mounting seat 34 and a first fixing seat 375 installed on the first busbar 13. In this application, there are three first mounting seats 31. Each first mounting seat 31 is equipped with a first rotary cylinder 311. The output end of the first rotary cylinder 311 drives the installation of a first pressure claw 312. The first pressure claw 312 abuts against the pressure surface 23 of the valve body 2.
[0026] The second mounting base 32 is provided with an abutment block 321 that abuts against the left end face of the valve body 2. The third mounting base 33 is provided with a plurality of abutment rods 331 that abut against the lower end of the valve body 2. The fourth mounting base 34 is provided with a push rod 342 assembly that abuts against the lower end of the valve body 2 and an adjustment assembly 38 that abuts against the front end and / or rear end of the valve body 2. The first fixed base 375 is hinged with a swing rod 372 that abuts against the right end face of the valve body 2. The end of the swing rod 372 is adjustablely provided with an adjustment member 36 that abuts against the front end and / or rear end of the valve body 2.
[0027] The adjustment assembly 38 includes a connecting seat 35, a first adjusting bolt 362, and a first nut 361. The connecting seat 35 is fixedly installed on the fourth mounting seat 34. The connecting seat 35 has a through hole 370. The first nut 361 is fixedly installed on the connecting seat 35, and the threaded hole on the first nut 361 is concentric and coaxial with the through hole 370 on the connecting seat 35. The first adjusting bolt 362 is threadedly fitted into the first nut 361.
[0028] In this application, there are two rocker arms 372, which are symmetrically arranged at the front and rear ends of the valve body 2. The adjusting component 36 includes a second adjusting bolt 382 and a second nut 381. The rocker arm 372 is provided with a through hole 370.

The second adjusting bolt 382 is threadedly engaged in the second nut 381.
[0029] The push rod 342 assembly includes a first drive member 341 and a push rod 342. The first drive member 341 is mounted on the fourth mounting base 34, and the push rod 342 is driven to be mounted on the output end of the first drive member 341. The end of the push rod 342 abuts against the lower end of the valve body 2.
[0030] A gripper 376 mechanism is mounted on the first fixed base 375. The gripper 376 mechanism includes a drive block 373, two swing rods 374, and two grippers 376. A second drive member 371 is installed inside the base 12. The drive block 373 is installed at the output end of the second drive member 371. The drive block 373 is provided with two opposing first mating grooves 3731. The two grippers 376 are slidably engaged with the first fixed base 375, and each gripper 376 has a second mating groove at its bottom. Two swing rods 374 are symmetrically hinged to the fixed base. Each swing rod 374 has a first end and a second end. The first end is fitted into the first mating groove 3731, and the second end of the swing rod 374 is located in the second mating groove 3761 of the gripper 376. When the drive block 373 moves, it drives the swing rod 374 to swing. The swing of the swing rod 374 drives the gripper 376 to move towards one side or away from one side.
[0031] The second clamping mechanism 4 includes two second fixed seats 43, two fifth mounting seats 41, and a sixth mounting seat 42 fixedly mounted on the second manifold 14. The two fifth mounting seats 41 are respectively disposed on both sides of the sixth mounting seat 42, and the two second fixed seats 43 are also respectively disposed on both sides of the sixth mounting seat 42. A second rotary cylinder 411 is mounted on each of the fifth mounting seats 41, and a second pressure claw 412 is driven to be mounted on the second rotary cylinder 411. A third driving member 421 is mounted on the sixth mounting seat 42, and a pressure block 422 is driven to be mounted on the third driving member 421. The second fixed seats 43 are used to abut against the second end face 22 of the valve body 2, and the second pressure claw 412 and the pressure block 422 are used to abut against the first end face 21 of the valve body 2.
[0032] The second fixed seat 43 is also provided with abutment seats 44 at both ends, and the abutment seats 44 at both ends abut and cooperate with the front and rear ends of the valve body 2 respectively.
[0033] It should be noted that the first drive component 341, the second drive component 371 and the third drive component 421 are cylinders or rotary cylinders.
[0034] Pressure gauges 15 are installed on the upper ends of both the first busbar 13 and the second busbar 14.
[0035] When using the valve body 2 during the machining of the first end face 21, the valve body 2's second end face 22 is engaged with the first fixed seat 375, and the lower end of the valve body 2 is engaged with the abutment rod 331 and the push rod 342. Then, by swinging the swing rod 372, the swing rod 372 is engaged with the right end face of the valve body 2. Further, by adjusting the second adjusting bolt 382, the second adjusting bolt 382 is engaged with the front and rear ends of the valve body 2, and the left end face of the valve body 2 is engaged with the abutment block 321. Therefore, while restricting the valve body 2's movement in the front-rear direction, the second bolt can also restrict the valve body 2's movement in the left-right direction through the engagement of the abutment block 321 and the swing rod 372. And by activating the first... A driving component 341 rotates the first pressure claw 312, causing it to abut against the pressure surface 23 of the valve body 2. This allows the valve body 2 to move vertically via the first pressure claw 312 and the first fixed seat 375. Furthermore, the second driving component 371 is activated, causing the driving block 373 to move closer to the second driving component 371. This causes the two swing rods 374 to swing towards each other, which in turn causes the two grippers 376 to move towards each other. The grippers 376 then clamp the valve body 2, restricting its movement in the front-back direction, thus fixing the valve body 2. At this point, the first end face 21 of the valve body 2 can be machined.
[0036] When processing the second end face 22 of the valve body 2, the first end face 21 of the valve body 2 is made to abut against the second fixed seat 43, thereby activating the two second rotary cylinders 411 to drive the second pressure claw 412 to rotate, thereby making the second pressure claw 412 abut against the bottom of the valve body 2. At the same time, the third drive member 421 is activated, thereby driving the pressure block 422 to abut against the bottom of the two valve bodies 2, so that the second end face 22 of the valve body 2 can be processed.
