Description

Technical Field

[0001] This utility model relates to presses, and more particularly to a gantry press with a tensioner. Background Technology

[0002] An automotive repair press is a piece of equipment used for automotive repair and maintenance, mainly for stamping, riveting, stretching and other operations on automotive parts.

[0003] Currently, the main structure of an automotive parts press includes a frame, a worktable mounted on the frame for positioning automotive parts, and a hydraulic cylinder assembly mounted on the frame for processing the parts on the worktable. When different parts are positioned on the worktable, the height of the worktable needs to be adjusted due to the different sizes of the parts. In existing technology, when adjusting the vertical position of the worktable, two workers are required to move the worktable up and down on the frame, and then use positioning pins to position the worktable. This operation method is time-consuming and labor-intensive. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a gantry-type press with a tensioner, which is time-saving and labor-saving in use.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A gantry-type press with a wire tensioner includes a frame, a lifting worktable mounted on the frame, a pin for positioning the worktable, and a hydraulic cylinder assembly mounted on the frame. The press further includes a wire tensioner comprising a guide wheel assembly, a pull rope, and a winding wheel mounted on the frame for winding the pull rope.

[0007] Both the winding wheel and the guide wheel assembly are mounted on the frame.

[0008] The pull rope is arranged on the frame through a guide wheel assembly and connected to the worktable. One end of the pull rope is wound around a winding wheel. The rotation of the winding wheel can retract and extend the pull rope, thereby driving the worktable to rise or fall.

[0009] Preferably, the winding reel is mounted on the side of the frame and is connected to a handle.

[0010] Preferably, the guide wheel assembly has four guide wheels: a first guide wheel located at the upper left of the workbench, a second guide wheel located at the lower left of the workbench, a third guide wheel located at the lower right of the workbench, and a fourth guide wheel located at the upper right of the workbench. The other end of the pull rope passes through the first guide wheel, the second guide wheel, the third guide wheel, and the fourth guide wheel in sequence and is connected to the right side of the workbench. The pull rope also passes through the first guide wheel and is connected to the left side of the workbench.

[0011] Preferably, the workbench includes a lifting frame and a positioning platform connected to the top of the lifting frame, and the left and right sides of the lifting frame have guide grooves that cooperate with the left and right sides of the frame.

[0012] Preferably, the frame has multiple vertically arranged first positioning holes on its left and right sides, and the lifting frame has second positioning holes on its left and right sides that can mate with the first positioning holes, and the pin is inserted into the first positioning holes and the second positioning holes.

[0013] The advantages of this utility model are: rotating the winding wheel can retract and extend the pull rope, and through the principle of labor-saving lever, it can drive the workbench to rise and fall on the frame, which significantly improves the convenience of adjusting the height of the workbench.

[0016] Combination Figures 1 to 2 The present invention provides a further description of the gantry-type press with a tensioner.

[0017] A gantry-type press with a wire tensioner includes a frame 1, a worktable 7 mounted on the frame 1, a pin 12 for positioning the worktable 7, and a hydraulic cylinder assembly 2 mounted on the frame 1. It is characterized by further including a wire tensioner, which comprises a guide wheel assembly, a pull rope 6, and a winding wheel 4 mounted on the frame 1 for winding the pull rope 6. Both the winding wheel 4 and the guide wheel assembly are mounted on the frame 1. The pull rope 6 is arranged on the frame 1 via the guide wheel assembly and connected to the worktable 7. One end of the pull rope 6 is wound around the winding wheel 4. Rotation of the winding wheel 4 can retract or release the pull rope 6, causing the worktable 7 to rise or fall.

[0018] Specifically, the winding wheel 4 is mounted on the left side of the frame 1 via a mounting base 3 and is connected to a handle 5. The handle 5 allows the winding wheel 4 to be rotated easily, thereby facilitating the winding and unwinding of the pull rope 6.

[0019] The guide wheel assembly has four guide wheels, which are respectively installed on the left and right sides of the frame 1. The four guide wheels are the first guide wheel 8 located on the upper left of the worktable 7, the second guide wheel 9 located on the lower left of the worktable 7, the third guide wheel 10 located on the lower right of the worktable 7, and the fourth guide wheel 11 located on the upper right of the worktable 7. The other end of the pull rope 6, that is, the end away from the winding wheel 4, passes through the first guide wheel 8, the second guide wheel 9, the third guide wheel 10, and the fourth guide wheel 11 in sequence before connecting to the right side of the worktable 7, and the pull rope 6 passes through the first guide wheel 8 before connecting to the left side of the worktable 7. That is, the other end of the pull rope 6 extends downward through the first guide wheel 8, passes through the left side of the worktable 7, and is connected to the left side of the worktable 7 by fasteners or binding, then continues downward through the second guide wheel 9, extends to the right through the third guide wheel 10, extends upward through the fourth guide wheel 11, and then extends downward through the locking member 13 to connect and fix it to the right side of the worktable 7. With this structure, the pull rope 6 can drive the worktable 7 to rise or fall when it is retracted and extended on the winding wheel 4.

[0020] The workbench 7 includes a lifting frame 71 and a positioning platform 72 connected to the top of the lifting frame 71. The left and right sides of the lifting frame 71 have guide grooves 713 that cooperate with the left and right sides of the frame 1. The positioning platform is used for positioning automotive parts.

[0021] The specific structure of the lifting frame 71 includes a front plate 711, a rear plate 712, and two connecting plates located between the front plate 711 and the rear plate 712. The guide grooves 713 on both sides of the lifting frame 71 are formed by the cooperation of the front plate 711, the rear plate 712 and the connecting plates, and are used to cooperate with the left and right sides of the frame 1 so that the lifting frame 71 can move stably up and down relative to the frame 1.

[0022] The frame 1 has multiple vertically arranged first positioning holes 14 on its left and right sides, and the lifting frame 71 has second positioning holes on its left and right sides that can mate with the first positioning holes 14. The pin 12 is inserted into the first positioning holes and the second positioning holes to position the worktable 7.

[0023] In use, when the height of the worktable 7 needs to be adjusted, pull out the pin 12, then rotate the winding wheel 4, and the worktable 7 will be moved to the desired height via the pull rope 6. Then, insert the pin 12 to fix the worktable 7. In this process, the pull rope 6 and the guide wheel work together to drive the worktable 7 to rise and fall on the frame 1 through the principle of effort-saving lever, which significantly improves the convenience of adjusting the height of the worktable 7.
