Movable clamping fixture for profile machining

Abstract

The utility model discloses a movable clamping fixture for profile machining. Comprising a clamp main plate, a moving mechanism fixed to the clamp main plate, a supporting plate fixed to the side face of the upper end of the clamp main plate, an upper pressing plate vertically and movably arranged at the upper end of the clamp main plate, a first air cylinder connected between the upper pressing plate and the clamp main plate, and a horizontal guide rail horizontally fixed to the side face of the clamp main plate. Compared with the prior art, the sectional material clamping device has the advantages that by arranging the moving mechanism, the sectional material can be dragged and moved after being clamped. Due to the fact that a plurality of clamps are arranged, when the section bar is fixed through some clamps, other clamps can release the section bar and allow the section bar to move freely. In this way, the position, needing to be machined, of the profile does not need to be manually adjusted, and therefore the operation process is greatly simplified.

Description

Technical Field

[0001] The utility model relates to the technical field of profile clamps, and particularly relates to a movable clamping fixture for profile processing. Background Technique

[0002] Profile processing is a common industrial manufacturing process, mainly used for mass production of various mechanical parts, furniture parts, etc. This processing method usually involves multiple process steps such as shearing, bending, and welding. However, in the actual processing process, profiles often need to go through multiple fixed links to ensure their accuracy and consistency in subsequent process steps.

[0003] Currently, the commonly adopted method in the industry is to use a fixed fixture for temporary positioning and fixing during profile processing. The main advantages of this method are simple and easy to implement, and it can ensure the stability and consistency of the profile during the entire processing process. However, this fixed method also has some obvious limitations:

[0004] 1. The profile cannot be easily moved. Since the fixture is permanently installed on the processing equipment, when the profile is processed in different processes, it often needs to be fixed at a specific position manually, which is both time-consuming and prone to introducing human errors.

[0005] 2. The contact part between the profile and the fixture cannot be directly processed. Since the profile needs to be positioned and fixed by the fixture, the contact part is often restricted to a certain extent, which makes it difficult to perform subsequent processing such as welding and turning at this part.

[0006] The existence of these limitations undoubtedly poses challenges to the precision and efficiency of profile processing and also has a negative impact on the operating cost of the production line. Therefore, we need to find a more effective method to solve this problem. Content of the Utility Model

[0007] In view of the above situation, to overcome the defects of the prior art, the utility model provides a movable clamping fixture for profile processing to solve the above problems.

[0008] To achieve the above purpose, a movable clamping fixture for profile processing of the utility model includes a fixture main board, a moving mechanism fixed to the fixture main board, a support board fixed to the upper side of the fixture main board, an upper pressure plate vertically movably arranged on the upper end of the fixture main board, a first cylinder connected between the upper pressure plate and the fixture main board, a horizontal guide rail horizontally fixed to the side of the fixture main board, a side pusher slidably connected to the horizontal guide rail, and a second cylinder connected between the side pusher and the horizontal guide rail.

[0009] The utility model has the following advantages compared with the prior art: By setting the moving mechanism, the utility model can realize the dragging movement of the profile after clamping the profile. Thanks to the fact that there are multiple clamps, when the profile is fixed by some of the clamps, other clamps can release the profile and allow it to move freely. This makes it unnecessary to manually adjust the position where the profile needs to be processed, thus greatly simplifying the operation process. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following will further describe in detail Figure 1-2 the specific embodiments of the utility model.

[0014] As Figure 1-2 given, a movable clamping fixture for profile processing of the utility model includes a fixture main board 10, a moving mechanism 80 fixed to the fixture main board 10, a support board 20 fixed to the upper side of the fixture main board 10 for supporting the profile from the bottom, an upper pressing plate 30 vertically movably arranged on the upper end of the fixture main board 10 for clamping the profile from above, a first cylinder 40 connected between the upper pressing plate 30 and the fixture main board 10 for driving the upper pressing plate 30 to move in the vertical direction, a horizontal guide rail 50 horizontally fixed on the side of the fixture main board 10, a side pushing member 60 slidably connected to the horizontal guide rail 50 for pushing the profile from the side, and a second cylinder 70 connected between the side pushing member 60 and the horizontal guide rail 50 for driving the side pushing member 60 to move horizontally.

[0015] The above structure will be described in detail below:

[0016] The fixture is movably mounted on the machine tool through a moving mechanism 80 and there are multiple fixtures. During use, the profile is placed on the support plate 20 of the fixture. By the telescopic movement of the second cylinder 70, the profile can be pushed from the side, causing the profile to traverse on the support plate 20 and then abut against the surface of the main fixture board 10. Then, by the contraction of the first cylinder 40, the upper pressing plate 30 is driven to move downward to clamp the profile. Through the setting of the moving mechanism 80, the fixture can drag the profile to move after clamping the profile. Since there are multiple fixtures, after some fixtures fix the profile, the other fixtures can release the profile and move freely, so as to make way for the position of the profile that needs to be processed. In addition, through the staggered clamping and movement of the fixtures, the profile can move continuously in the machine tool without manual adjustment of the position of the profile.

[0017] A bottom connecting plate 11 is fixed at the lower end of the main fixture board 10. The lower end of the first cylinder 40 is fixedly connected to the bottom connecting plate 11. The bottom connecting plate 11 is fixed with a vertically arranged moving plate 12. The moving plate 12 is fixed with a moving block 13. The moving block 13 can be slidably connected to the guide rail fixed on the machine tool, so as to realize the moving guidance of the fixture. In some embodiments, the moving mechanism 80 includes a servo motor 81 fixed on the moving plate 12 and the bottom connecting plate 11. The output shaft of the servo motor 81 is connected with a helical gear 82. The helical gear 82 can cooperate with the rack fixed on the machine tool. By driving the rotation of the helical gear 82 by the servo motor 81, the fixture is driven to move on the machine tool.

[0018] The first cylinder 40 is located between the main fixture board 10 and the moving plate 12. A dust-proof plate 16 is connected between the main fixture board 10 and the moving plate 12. The setting of the dust-proof plate 16 can play a role in dust-proofing the telescopic part of the first cylinder 40 and extend the service life of the first cylinder 40.

[0019] Specifically, the upper end of the first cylinder 40 is fixed with a main pressure rod 31 through a floating joint 41. The main pressure rod 31 is fixedly connected to the upper pressing plate 30. The main pressure rod 31 is fixed with a slider 32. The main fixture board 10 is fixed with a linear guide rail 17. The slider 32 is slidably connected to the linear guide rail 17. Through the setting of the slider 32 and the linear guide rail 17, the movement of the main pressure rod 31 can be guided, and the stability of the up and down movement of the upper pressing plate 30 can be improved.

[0020] The telescopic end of the second cylinder 70 is fixedly connected to the lower end of the side pusher 60 through a connecting piece 61. The connecting piece 61 is slidably connected to the horizontal guide rail 50. Through the setting of the connecting piece 61 and the horizontal guide rail 50, the horizontal movement of the side pusher 60 can be guided.

[0021] The upper end of the side pusher 60 is fixed with a side pushing block 62.

[0022] In some embodiments, a wire passing plate 80 is fixed to the telescopic end of the second cylinder 70, and a solenoid valve 90 is fixed to the wire passing plate 80. The solenoid valve 90 is connected to the hydraulic oil circuits of the first cylinder 40 and the second cylinder 70.

[0023] When the movable clamping fixture for profile processing of the present utility model is in use, first, the profile is placed on the support plate 20 of the fixture. Then, the contraction of the second cylinder 70 drives the side pusher 60 to move, pushing the profile to move horizontally and abut against the main fixture board 10. Next, the contraction of the first cylinder 40 drives the upper pressing plate 30 to move downward to complete the clamping of the profile. The setting of the moving mechanism 80 enables the fixture to drag the profile to move after clamping the profile. And since multiple fixtures are provided, after the profile is fixed by some fixtures, the other fixtures can release the profile and move freely, so as to make way for the position where the profile needs to be processed, without manual adjustment of the position, greatly simplifying the operation process.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
