Description

Technical Field

[0001] The utility model relates to the technical field of drilling machines, in particular to a guardrail edge strip punching machine. Background Art

[0002] Punching holes is a common operation for processing profiles such as guardrail edge strips. After punching, the edge strips can be assembled into guardrails by bolts. In order to prevent the profile from moving during drilling, a clamp is generally used to clamp the profile.

[0003] After searching, the Chinese utility model patent with application number 202322085561.3 discloses an automatic punching machine for aluminum profiles, which clamps the aluminum profiles by two sets of clamps and drills holes by moving the drill downward. When the aluminum profile needs to be punched multiple times, the external power supply of the first motor is connected, and the first motor is started to drive the incomplete gear to rotate, so that the incomplete gear can drive the rack plate to drive the aluminum profile to move. After the incomplete gear rotates to a certain angle, it no longer engages with the rack plate, so that the moving distance of the rack plate is fixed. At the same time, the force of the drill bit on the aluminum profile is from top to bottom, so the position of the rack plate will not move.

[0004] The inventor believes that in the above patent technology, the movement of the clamping device can drive the automatic feeding of the profile, but when drilling, the drill bit of the drill must exert a certain pressure on the profile in order to drill smoothly into the profile. In the above patent technology, the clamping device cannot be kept under the drill, so that when drilling, the bottom of the profile is prone to tilting due to the lack of support. In addition, in the field of drilling holes in the profile, drill chips will splash everywhere, which is a common problem.

[0005] Therefore, the present application proposes a guardrail edge strip punching machine that is more stable when drilling. Utility Model Content

[0006] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a guardrail edge strip punching machine to solve the above problem.

[0007] To achieve the above-mentioned purpose, the utility model provides a guardrail edge punching machine, comprising a drilling platform, a clamp arranged on the surface of the drilling platform and a drilling rig arranged above the drilling platform, the clamp comprising three groups of clamping mechanisms arranged in sequence on the drilling platform, the two clamping mechanisms located on the outer side move synchronously in the length direction of the profile to form a moving pair for moving the profile, the clamping mechanism located in the middle position constitutes a fixed pair for fixing the profile, and the three groups of clamping mechanisms are specifically configured as follows: the clamping mechanism comprises a base plate, a fixed baffle is fixed to one side of the base plate, a cylinder is fixed to the other side of the base plate, the cylinder is connected to a clamping plate, the base plate of the clamping mechanism in the middle position is fixed to the surface of the drilling platform, and the base plates of the two clamping mechanisms on the outer side are slidably arranged on the surface of the drilling platform.

[0008] Compared with the prior art, the utility model has the following benefits: 1) The guardrail edge strip punching machine of the utility model realizes automatic loading by moving the profile through the moving pair. When punching, the support rollers on the moving pair are used to support from both sides of the bottom of the profile, and the fixed pair is used to support the punching position at the bottom of the profile. The three-point support method makes the punching more stable; 2) When punching, the top and both sides of the telescopic cover are combined with the fixed baffle and the clamping block to form a relatively closed space, and then the drill bit of the drilling rig moves downward and drills holes to prevent drill chips from splashing, thereby solving the common problem that drill chips are easily splashed when drilling with existing punching machines.

Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings:

[0011] Figure 2 It is a front view structural schematic diagram of the utility model.

[0012] Figure 3 For this utility model Figure 1 Enlarged structural diagram at A in the middle. DETAILED DESCRIPTION

[0013] The following is combined with Figure 1-3 The specific implementation modes of the present utility model are further described in detail.

[0014] Depend on Figure 1-3The guardrail edge punching machine of the utility model comprises a drilling platform 10, a fixture arranged on the surface of the drilling platform 10 for clamping the profile, and a drilling machine 20 arranged above the drilling platform 10 for punching holes in the fixture. The above constitutes a basic punching machine structure, which will not be described in detail here. The main improvements of the utility model are:

[0015] The fixture includes three groups of clamping mechanisms 30 arranged in sequence on the drilling platform 10. The two clamping mechanisms 30 located on the outside move synchronously in the length direction of the profile to form a moving pair for moving the profile. The clamping mechanism 30 located in the middle position is fixed in position to form a fixed pair for fixing the profile. When in use, the moving pair clamps the profile for movement, stops when it moves below the drilling position of the puncher, and then the fixed pair fixes the profile, and drilling is performed through the drilling machine 20. During the drilling process, the moving pair releases the profile and returns to its original position. After drilling is completed, the fixed pair releases the profile, and the moving pair clamps the profile again and moves it below the drilling position. The above actions are repeated until drilling is completed. The profile is moved by the two clamping mechanisms 30 to realize automatic loading. When drilling, the fixed pair used to support the profile is always supported directly below the drilling position, so that the profile has better stability when drilling.

[0016] It is understandable that when the profile needs to be completely punched through, a punching groove should be provided on the bottom plate 31 of the fixing pair.

[0017] The three groups of clamping mechanisms 30 are specifically configured as follows: the clamping mechanism 30 includes a base plate 31, a fixed baffle 32 is fixed to one side of the base plate 31, a cylinder 33 is fixed to the other side of the base plate 31, and the cylinder 33 is connected to a clamping block 34. The base plate 31 of the clamping mechanism 30 in the middle position is fixed to the surface of the drilling platform 10, and the base plates 31 of the two clamping mechanisms 30 on the outside are slidably set on the surface of the drilling platform 10. When in use, the profile is first sent into the gap between the fixed baffle 32 and the clamping block 34 of the moving pair, and the cylinder 33 of the moving pair is extended to clamp the profile, and then the moving pair drives the profile to move to the drilling position, and the cylinder 33 of the fixed pair is extended to drive the clamping block 34 to clamp the profile, and the drilling rig 20 is used to drill a hole. During the drilling process, the moving pair returns to its original position and clamps the profile. After the drilling rig 20 completes the drilling, the moving pair moves the profile to the drilling position again, and the above actions are repeated until the drilling is completed.

[0018] The surface height of the bottom plate 31 of the clamping mechanism 30 located in the middle position is higher than the height of the bottom plates 31 of the two clamping mechanisms 30 located at the outer positions. In this way, when drilling, the profile is fixed in position by the fixed pair, and the movable pair can first move to the original position and clamp the profile. After the drilling rig 20 completes one drilling, the profile can be quickly moved a distance over.

[0019] In order to prevent drill cuttings from splashing during the drilling process, a telescopic cover 50 is vertically slidably installed on the head of the drill rig 20. The telescopic cover 50 is specifically a U-shaped structure, and a spring 51 is connected between the telescopic cover 50 and the head of the drill rig 20. In this way, when the drill rig 20 moves downward and drills, the lower end of the telescopic cover 50 will first contact the bottom plate 31, so that the top and both sides of the telescopic cover 50 are surrounded by the fixed baffle 32 and the clamping block 34 to form a relatively closed space, and then the drill bit of the drill rig 20 moves downward and drills to prevent drill cuttings from splashing. The spring 51 will be compressed during the drilling process. After the drilling is completed, the drill bit of the drill rig 20 moves upward. Under the action of the spring 51, the telescopic cover 50 moves downward relative to the drill bit and returns to the initial position.

[0020] In order to facilitate the collection of drill cuttings, a vacuum cleaner 53 is connected to the side of the telescopic cover 50 through a connecting pipe 52. The vacuum cleaner 53 is fixed to the surface of the drilling platform 10. When drilling, the drill cuttings are blocked in the space surrounded by the telescopic cover 50, the fixed baffle 32 and the clamping block 34. The drill cuttings are extracted by the vacuum cleaner 53, which facilitates the timely cleaning of the drill cuttings and prevents the drill cuttings from falling into the gaps on the surface of the drilling platform 10 and becoming difficult to clean.

[0021] In order to support the bottom of the profile from both sides of the punching position and solve the problem of instability in the profile caused by only one supporting point during the punching process mentioned in the background technology, support rollers 35 are provided on the surface of the bottom plate 31 of the two clamping mechanisms 30 located on the outside. In this way, the profile can be supported from the bottom by the support rollers 35. When drilling, the profile is kept in a fixed position by the action of the fixed pair. When the movable pair moves, the support rollers 32 on the bottom plate 31 roll on the bottom surface of the profile, which can also play a supporting role.

[0022] A slide rail 11 is fixed on the surface of the drilling platform 10 , a bottom plate 31 of the fixed pair is fixed on the top of the slide rail 11 , and a bottom plate 31 of the movable pair is slidably disposed at both ends of the slide rail 11 .

[0023] A motor screw mechanism 40 is installed on the surface of the drilling platform 10, and the motor screw mechanism 40 drives the bottom plate 31 of the moving pair to move.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
