[0031] In some embodiments, please refer to the attached Figures 1-5 specification, an adjustable processing fixture includes a mold equipment main body 1, and a calibration mechanism 2 for calibrating according to the height of the workpiece and a clamping mechanism 3 for pressing the workpiece are installed on the mold equipment main body 1;

[0033] When the present utility model is in use, the feeding mechanism places the workpiece to be processed on the mold equipment main body 1. The height adjustment component 21 adjusts the height of the mold equipment main body 1 according to the height of the workpiece, so as to expose the processing position of the workpiece.

[0034] Embodiment 2

[0035] In some embodiments, such as Figures 1-5As shown, as a preferred embodiment of the present utility model, the main body 1 of the mold device includes a substrate 11, an upper plate 12, support rods 13, a support base 14, and a workpiece placement groove 15. Four support rods 13 are respectively and fixedly installed around the lower end of the upper plate 12. The side walls of the four support rods 13 are respectively slidably connected to the four sides of the substrate 11. A plurality of support bases 14 are equidistantly arranged and are all fixedly installed on the upper end of the substrate 11. Two groups of support bases 14 are provided and are symmetrically arranged on the front and rear sides of the upper end of the substrate 11 respectively. A plurality of workpiece placement grooves 15 are equidistantly arranged and are all formed on the upper end of the upper plate 12. Two groups of workpiece placement grooves 15 are provided and are symmetrically arranged on the front and rear sides of the upper plate 12 respectively.

[0036] The substrate 11 is connected to the height adjustment assembly 21.

[0037] The upper plate 12 is connected to both the height calibration assembly 22 and the clamping mechanism 3, and the workpiece placement groove 15 is connected to the clamping mechanism 3.

[0038] The height adjustment assembly 21 includes a first connecting rod 212, a second connecting rod 213, and a hollow single-piston cylinder 214. The lower end of the first connecting rod 212 is hinged to the upper end of the substrate 11. The upper end of the first connecting rod 212 is hinged to one end of the second connecting rod 213. The other end of the second connecting rod 213 is hinged to the lower end of the upper plate 12. Two first connecting rods 212 and two second connecting rods 213 are provided and are respectively located on the left and right sides of the upper end of the substrate 11. The hollow single-piston cylinder 214 is fixedly installed in the middle of the upper end of the substrate 11. The upper end of the piston rod of the hollow single-piston cylinder 214 is fixedly connected to the lower end of the upper plate 12. Two hollow single-piston cylinders 214 are provided and are respectively located on the front and rear sides of the upper end of the substrate 11.

[0039] The height adjustment assembly 21 further includes a first double-acting synchronous cylinder 211. The first double-acting synchronous cylinder 211 is located between the substrate 11 and the upper plate 12. The left output end of the first double-acting synchronous cylinder 211 is hinged to the connection point of the left first connecting rod 212 and the second connecting rod 213. The right output end of the first double-acting synchronous cylinder 211 is hinged to the connection point of the right first connecting rod 212 and the second connecting rod 213.

[0040] The height calibration assembly 22 includes a mounting base 221 and a cylinder 222. The mounting base 221 is fixedly installed on the upper end of the upper plate 12. The cylinder 222 is fixedly installed on the upper end of the mounting base 221.

[0041] The cylinder 222 is used for calibrating the height of the workpiece.

[0042] Two mounting bases 221 and two cylinders 222 are provided and are centrally symmetrically arranged on the upper plate 12.

[0043] When the utility model is in use, after the feeding mechanism places the workpiece to be processed in the workpiece placement groove 15, the lower end of the workpiece is supported by the support base 14. Then, the air cylinder 222 is started. Initially, the uppermost end of the workpiece is lower than the height of the output end of the air cylinder 222. Then, the first bidirectional synchronous air cylinder 211 and the hollow single-piston air cylinder 214 are started, so that the connection parts of the first connecting rods 212 and the second connecting rods 213 on the left and right sides are driven by the two output ends of the first bidirectional synchronous air cylinder 211 to move inwards. The first connecting rods 212 on the left and right sides thus drive the substrate 11 to slide upwards on the support rods 13. The piston rod of the hollow single-piston air cylinder 214 descends as the substrate 11 rises, so as to hold the upper plate 12 firmly to maintain the stability of the upper plate 12 and prevent the upper plate 12 from shaking when the first bidirectional synchronous air cylinder 211 drives the substrate 11 to adjust the position, thereby damaging the workpiece. When the first bidirectional synchronous air cylinder 211 controls the substrate 11 to rise to an appropriate height, the support base 14 drives the workpiece to an appropriate position, and the upper end of the workpiece just contacts the lower end of the output end of the air cylinder 222, and the processing part of the workpiece is exposed, realizing the height calibration of the workpiece. Through the height adjustment of the substrate 11 by the first bidirectional synchronous air cylinder 211 and the height calibration of the workpiece by the air cylinder 222, the precise positioning of the workpiece processing position is realized, ensuring the precision of the workpiece processing.
