[0027] See also Figures 1 to 4 The utility model discloses an upper jig, which includes a base 1, a support plate 2 and a cylinder 3. The base 1 is configured as a plate body with a flat top surface, the cylinder 3 is disposed on the top surface of the base 1, and the output end of the cylinder 3 extends away from the base and toward the top side of the base; the support plate 2 is disposed on the top side of the cylinder 3, and the bottom surface of the support plate 2 is connected to the output end of the cylinder 3, so that the cylinder 3 can push the support plate 2 to rise and fall relative to the base 1. In actual applications, when the top surface of the workpiece needs to be machined, the upper jig is installed on the bottom side of the output end of the processing equipment, the workpiece is placed on the top surface of the support plate 2, and is positioned and fixed; at this time, the cylinder 3 drives the workpiece to rise to a preset height toward the output end of the processing equipment by lifting the support plate 2, and then the output end of the processing equipment can process the top surface of the workpiece. Compared with traditional fixtures, the upper fixture of the utility model positions and clamps the workpiece by supporting the workpiece from the bottom side. While ensuring that the workpiece is stably supported, it can more accurately control the distance between the workpiece and the output end of the processing equipment, thereby improving the processing accuracy of the processing equipment on the top side surface of the workpiece.
[0028] Furthermore, the upper fixture also includes two guide plates 4, which are arranged on the top side surface of the base 1, and the bottom end of each guide plate 4 is connected to the top side surface of the base 1, and the top end of each guide plate 4 extends to a preset height away from the base 1. Specifically, the support plate 2 and the cylinder 3 are arranged between the two guide plates 4, and the two ends of the support plate 2 are respectively matched with and slidably connected to the inner wall of the two guide plates 4 facing each other, so that the cylinder 3 can drive the support plate 2 to rise and fall along the two guide plates 4. During the lifting process of the support plate 2, the two guide plates 4 can limit the lifting direction of the support plate 2 and effectively improve the lifting stability of the support plate 2 and its support stability for the workpiece.
[0029] Furthermore, the two guide plates 4 are arranged parallel to each other, thereby forming a rectangular receiving space. In this embodiment, the support plate 2 is arranged as a rectangular plate, so that the two parallel ends of the support plate 2 can be matched and connected with the inner walls of the two guide plates 4, thereby limiting the lifting direction of the support plate 2.
[0030] Furthermore, the upper fixture also includes two limiting end plates 5, which correspond to the two guide plates 4 one by one and are respectively arranged at the top ends of the two guide plates 4; wherein each limiting end plate 5 extends toward one side edge of the opposite limiting end plate 5 by a preset distance, thereby forming a blockage for the two ends of the support plate 2, thereby limiting the lifting and lowering range of the support plate 2 between the two guide plates 4, thereby preventing the support plate 2 from being excessively lifted and falling out from between the two guide plates 4.
[0031] Furthermore, the upper fixture is provided with a plurality of cylinders 3, which are correspondingly arranged on the bottom side of the support plate 2, so that the plurality of cylinders 3 can cooperatively drive the support plate 2 to rise and fall, thereby improving the stability of the lifting of the support plate 2 and the stability of its support for the workpiece. In this embodiment, four cylinders 3 are arranged on the bottom side of the support plate 2, and the four cylinders 3 are respectively arranged at the four top corners of the rectangular support plate 2, thereby further improving the stability of the lifting of the support plate 2 and the stability of its support for the workpiece.
[0032] Furthermore, the upper fixture is provided with a plurality of support plates 2, and four cylinders 3 are provided on the bottom side of each support plate 2; wherein, the plurality of support plates 2 are arranged in parallel in pairs, and are extended along the length direction of the two guide plates 4 and arranged between the two guide plates 4; the two ends of each support plate 2 are respectively matched with the inner walls of the two guide plates 4 facing each other and are slidably connected. In practical applications, the plurality of support plates 2 can collaboratively lift the workpiece, thereby increasing the contact area between the upper fixture and the workpiece, so as to enhance the support stability of the upper fixture on the workpiece; the plurality of support plates 2 can also lift multiple workpieces separately, thereby increasing the workpiece fixing amount of the upper fixture, and realizing batch processing of the workpiece by the processing equipment.
[0033] Furthermore, each pallet 2 is also provided with a partition 21, which is arranged on the top side surface of the pallet 2, and the partition 21 is arranged in the middle of the pallet 2, so as to separate the pallet 2 into two adjacent receiving spaces. Specifically, when a number of pallets 2 are arranged in parallel and equidistantly, a number of partitions 21 corresponding to the pallets 2 are arranged in a straight line, so that a number of pallets 2 can be combined to form a larger receiving space, and a number of partitions 21 combined can divide the receiving space formed by the combination of a number of pallets 2 as a whole. In practical applications, each pallet 2 has two unit receiving spaces, and a number of pallets 2 combined can promote the combination of unit receiving spaces to form receiving spaces of various sizes, thereby improving the versatility of the top fixture to accommodate workpieces of various sizes.
[0034] In summary, the upper jig disclosed in the utility model sets the support plate on the top side of the cylinder, and the bottom surface of the support plate is connected to the output end of the cylinder, so that the cylinder can push the support plate to rise and fall relative to the base. When the top surface of the workpiece needs to be machined, the upper jig is installed on the bottom side of the output end of the processing equipment, and the workpiece is placed on the top surface of the support plate and positioned and fixed; at this time, the cylinder drives the workpiece to rise to a preset height toward the output end of the processing equipment by lifting the support plate, so that the output end of the processing equipment can process the top surface of the workpiece. Compared with the traditional jig, the upper jig of the utility model positions and clamps the workpiece by lifting the workpiece from the bottom side. While ensuring that the workpiece is stably supported, it can more accurately control the distance between the workpiece and the output end of the processing equipment, thereby improving the processing accuracy of the processing equipment on the top surface of the workpiece.
