DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] according to Figure 1-4As shown, an adjustable fixture for processing mechanical parts includes a base 1, on which two support assemblies are respectively installed, and the support assemblies include two L-shaped support plates 3 and two support sleeves 2. The two support sleeves 2 are relatively arranged on the base 1, and the vertical end of each L-shaped support plate 3 is slidably installed in the support sleeve 2, and a fixing plate 18 is fixedly installed between the vertical ends of each two corresponding L-shaped support plates 3, and the straight ends of the L-shaped support plates 3 are relatively arranged. Both sides of the first fixture body 4 and the second fixture body 5 are provided with sliding grooves 15, and the first fixture body 4 and the second fixture body 5 are respectively slidably connected to the straight ends of the L-shaped support plates 3 in the two support assemblies through the sliding grooves 15, and a load-bearing plate 7 is fixedly installed on the fixed plate 18 below the second fixture body 5, and a mounting seat 8 is provided on the load-bearing plate 7, and a screw rod 9 is screwed on the mounting seat 8, one end of the screw rod 9 is connected to the second fixture body 5, and the other end of the screw rod 9 is connected to the handle 10.

[0021] Baffles are provided at the tail of the slide grooves 15 on both sides of the first clamp body 4. Threaded holes 16 are opened on both sides of the top of the first clamp body 4. Fixing bolts 6 are screwed on the threaded holes 16. The bottom of the fixing bolts 6 matches the straight end of the L-shaped support plate 3.

[0022] A mounting groove is provided on the load-bearing plate 7, and a mounting hole is provided on one side of the mounting groove. A mounting seat 8 is slidably installed in the mounting groove, and a limit plate 11 is fixedly installed on the middle and lower part of the mounting seat 8. A connecting rod 14 is slidably installed on the limit plate 11, and the connecting rod 14 cooperates with the mounting hole.

[0023] A connecting groove 17 is provided on one side of the second clamp body 5 . The top of the connecting groove 17 is open, and one end of the lead screw is movably installed in the connecting groove 17 .

[0024] A plurality of insertion holes 12 are vertically formed on the support sleeve 2 and the L-shaped support plate 3 . A latch 13 is fitted in one of the insertion holes 12 of the support sleeve 2 and the L-shaped support plate 3 .

[0025] Working principle: When it is necessary to adjust the height of the first clamp body 4 and the second clamp body 5, pull out the pin 13 and pull the fixing plate 18 to increase the height of the L-shaped support plate 3, and then adjust the height of the first clamp body 4 and the second clamp body 5, and then insert the pin 13 back into the socket 12; when it is necessary to replace the clamp, loosen the fixing bolt 6, the first clamp body 4 is separated from the L-shaped support plate 3 through the slide groove 15, and a new first clamp body 4 is replaced, which is installed on the L-shaped support plate 3 through the slide groove 15 and fixed with the fixing bolt 6.
