Description

Technical Field

[0001] The utility model relates to training equipment, in particular to a workbench for mechanical design, manufacturing and automation training. Background Art

[0002] In the teaching process of mechanical design, manufacturing and automation major, metalworking training is an indispensable practical teaching link. Metalworking training includes turning, milling, special processing (wire cutting, laser processing), CNC turning, CNC milling, benchwork, sand casting and other projects, which can effectively cultivate students' hands-on ability and enable students to understand traditional mechanical manufacturing processes and modern mechanical manufacturing technologies.

[0003] When conducting bench training, students need to use a bench vise on the training workbench to fix the workpiece, and then use tools such as hacksaws and files to manually process the workpiece. However, the existing training workbench cannot adjust the table height during use. Due to the different heights of students and the large height difference between boys and girls, taller and shorter students have more inconveniences when using the training workbench.

[0004] After searching, the patent with announcement number CN221020926U discloses a new type of multifunctional benchwork training workbench that can be raised and lowered. Through the designed connecting grooves, connecting rods, fixing rods, screws, bearings and hand wheels, the height of the workbench can be quickly and conveniently raised and lowered according to usage requirements. At the same time, with the designed positioning holes and positioning rods, the screws can be firmly limited after adjustment to avoid looseness. Compared with the existing technology, the lifting and lowering adjustment of the multifunctional benchwork training workbench is greatly facilitated.

[0005] Although the above scheme can adjust the table height of the training workbench, since the two screws are threadedly connected to the crossbeam and the top ends of the screws are rotatably connected to the table top through bearings, the two screws need to be rotated at the same speed at the same time to achieve the lifting and lowering of the table top. In addition, the hand-cranked wheel for operating the screws is located under the table top and at a relatively low height, so the operation is very inconvenient and needs to be improved.

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] See also Figures 1 to 4In the embodiment of the utility model, a workbench for mechanical design, manufacturing and automation training includes a table top 1, a U-shaped transmission box 2 is fixedly installed at the bottom of the table top 1, and a plurality of sleeves 3 are fixedly installed at the bottom of the U-shaped transmission box 2, and the bottom ends of the sleeves 3 are slidably penetrated with support tubes 4, and the bottom ends of the support tubes 4 are all installed with support plates 5, and the adjacent support tubes 4 are fixedly connected to each other through a second connecting rod 21. A linear drive mechanism for driving the support tubes 4 is installed in the sleeve 3, and the top of the linear drive mechanism is inserted into the U-shaped transmission box 2 and then connected to each other in transmission, and the outer wall of the U-shaped transmission box 2 is rotatably penetrated with a transmission shaft 15, and one end of the transmission shaft 15 is located in the U-shaped transmission box 2 and is transmission-connected to a linear drive mechanism, and the other end of the transmission shaft 15 is detachably connected with a handwheel 18, a drawer 22 is installed at the bottom of the table top 1, and a bench vise 23 is installed at the top of the table top 1.

[0024] By adopting the above scheme, the utility model can, when in use, use the bench vise 23 to clamp and fix the workpiece to be processed, and the drawer 22 can store tools such as hacksaws, saw blades, brushes and various files used in practical training. Before doing practical training, students of different heights can rotate the transmission shaft 15 through the handwheel 18, and then drive each linear drive mechanism to rotate, so as to adjust the length of the support tube 4 extending out of the sleeve 3, thereby adjusting the height of the table 1, so that the height of the bench vise 23 meets the students' own usage requirements, and the operation is simple and convenient. After completing the height adjustment of the table 1, the handwheel 18 can be removed from the transmission shaft 15 and stored in the drawer 22, so as to avoid the handwheel 18 interfering with the students' activities, and at the same time, it can avoid the height of the table 1 changing due to accidental touching of the handwheel 18.

[0033] Specific combination Figure 1 In one embodiment of the present invention, the adjacent sleeves 3 are fixedly connected to each other via a first connecting rod 20 to improve the stability of the support for the table plate 1.

[0034] Specific combination Figure 1 and Figure 2 In one embodiment of the utility model, a second screw 6 is penetrated through the bottom end of the support tube 4 through a threaded hole, and the bottom end of the second screw 6 is rotatably connected to the support plate 5 through a bearing seat, and a second nut 7 is fixedly sleeved on the outer wall of the second screw 6 located below the support tube 4, and a plurality of through holes 8 are penetrated through the top surface of the support plate 5.

[0035] Through the cooperation between the second screw 6 and the threaded hole, the distance between the support plate 5 and the support tube 4 can be adjusted by operating the second nut 7 with a wrench to rotate the second screw 6, so that when the ground is uneven, it can ensure that each support plate 5 is in stable contact with the ground.
