Best mode of the present application

[0034] In order to further understand the features, technical means and specific purposes and functions of the present application, the present application will be described in further detail below in combination with the drawings and specific embodiments.

[0035] Referring to Figures 1-3, a positioning and clamping device for luggage lock stamping includes a machine shell 1, a punch station 2 arranged on the machine shell 1 to punch the workpiece, a punch cylinder 3 mounted on the machine shell 1 to drive the punch station 2 to rise and fall vertically, a pair of limiting plates 31 to place the workpiece, and a self-adaptive clamping mechanism 4 arranged on the machine shell 1 to automatically clamp and limit the workpiece, the self-adaptive clamping mechanism 4 including a moving block 41, a moving roller abutting plate 42 arranged in the moving block 41 in a horizontal straight line sliding direction and used to contact the workpiece, and a connecting driving mechanism 5 used to drive the moving block 41 and the moving roller abutting plate 42 to slide in a horizontal straight line direction, the positioning and clamping device for luggage lock stamping further includes a burr prevention mechanism 6 arranged on the machine shell 1 to lubricate the punch station 2 after punching, the machine shell 1 is provided with a punching slot for the punch station 2 to punch the workpiece, the punching slot is used to discharge the waste after punching, the machine shell 1 is provided with a limiting and fixing block to abut the workpiece, a plurality of rubber sliding wheels are arranged on the moving roller abutting plate 42 in a rotating manner to contact the workpiece, so as to avoid direct contact with the workpiece and cause extrusion damage to the workpiece.

[0036] When the workpiece on the shell 1 needs to be clamped, first, the punch cylinder 3 is started, and then the punch table 2 is driven to descend vertically until the punch table 2 contacts the workpiece on the shell 1. During the vertical descent of the punch table 2, the moving block 41 and the moving roller contact plate can be driven to contact the workpiece by the connecting drive mechanism 5. During sliding, the moving roller abutting plate 42 can first contact the workpiece, and after contact, the moving block 41 can continue to slide horizontally and linearly. After the moving roller abutting plate 42 contacts the workpiece, it stops moving. At this time, the workpiece can be abutted on the moving roller abutting plate 42 and the fixed block, so as not to affect the continued descending and punching movement of the punch table 2, so that the moving roller abutting plate 42 can always contact the workpiece and automatically clamp and fix the workpiece, and can clamp and limit workpieces of different widths without disassembling and replacing the clamp to adaptively clamp the workpiece.

[0037] Referring to FIGS. 4 and 5, the adaptive clamping mechanism 4 further includes a moving chamber 43, a telescopic spring 44, and a connecting piece 45. The moving chamber 43 is opened in the moving block 41, and the moving chamber 43 is used for the horizontal and linear sliding of the moving roller abutting plate 42. The telescopic spring 44 is arranged in the moving chamber 43, and the two ends of the telescopic spring 44 are fixed with the end of the moving chamber 43 and the moving roller abutting plate 42, respectively. The connecting piece 45 is arranged on the moving block 41, and the connecting piece 45 is fixedly connected with the moving block 41.

[0038] When the moving block 41 and the moving roller abutting plate 42 contact the workpiece, the moving roller abutting plate 42 is limited by the workpiece and moves to the horizontal and linear sliding in the moving block 41 along the moving chamber 43 opened in the moving plate, and in this process, the telescopic spring 44 is compressed. The opening of the moving chamber 43 can slide the moving roller abutting plate 42 after contacting the workpiece, so that the movement of the moving block 41 does not always push the moving roller abutting plate 42 to abut against the workpiece, avoiding damage to the workpiece caused by extrusion force after contacting the workpiece.

[0039] Referring to FIGS. 3-8, the connecting drive mechanism 5 includes a mounting seat 51, a horizontal and linear slot 52, a sliding displacement block 53, and a hinged rod 54. The mounting seat 51 is arranged on the limiting plate and has a pair of two sides close to the punch table 2. The horizontal and linear slot 52 is opened in the mounting seat 51. The sliding displacement block 53 is arranged horizontally and linearly on the horizontal and linear slot 52, and the sliding displacement block 53 is fixedly connected with the connecting piece 45. The hinged rod 54 is rotatably arranged on the sliding displacement block 53 and the punch table 2, respectively.

[0040] When the stamping table 2 is vertically lowered, the articulated rod 54 drives the rotationally connected sliding displacement block 53 to slide horizontally along the horizontal linear groove 52 on the mounting base 51. When the sliding block slides, the connecting piece 45 and the sliding displacement block 53 fixedly connected thereto move, so that when the stamping table 2 is lowered, the sliding displacement block 53 and the moving roller abutting plate 42 are automatically moved by the articulated rod 54, and the moving roller abutting plate 42 automatically clamps and fixes the workpiece when the stamping table 2 is lowered, without the need for manual clamping of the workpiece, and the workpiece is prevented from shifting or loosening when being stamped.

[0041] Referring to FIG. 8, the connecting driving mechanism 5 further comprises abutting blocks 55, cooperating blocks 56 and displacement grooves 57. The abutting blocks 55 are arranged on the stamping table 2 and have a plurality of abutting blocks. The cooperating blocks 56 are arranged on the abutting blocks 55. The displacement grooves 57 are arranged on the articulated rod 54, and the cooperating blocks 56 are in sliding cooperation with the displacement grooves 57. The displacement grooves 57 are used to limit the sliding of the cooperating blocks 56.

[0042] During the vertical lowering of the stamping table 2, the cooperating blocks 56 on the abutting blocks 55 slide along the displacement grooves 57 on the articulated rod 54, so that the articulated rod 54 is not directly driven to swing by the cooperating blocks 56 at the first time when the stamping table 2 is lowered, but the sliding displacement block 53 and the moving roller abutting plate 42 are moved by the articulated rod 54 and the sliding block after the cooperating blocks 56 slide along the displacement grooves 57 and contact, achieving the horizontal linear sliding effect of the sliding displacement block 53 and the moving roller abutting plate 42.

[0043] Referring to FIGS. 3-7, the burr prevention mechanism 6 comprises a toothed plate 61, a damping rod 62, a contact gear 63 and a swing arm 64. The toothed plate 61 is arranged on the stamping table 2 and has a pair of toothed plates. The damping rod 62 is rotationally arranged on the casing 1 and is close to one side of the toothed plate 61. The contact gear 63 has a pair of contact gears and is arranged on the damping rod 62. The contact gear 63 is in meshing cooperation with the toothed plate 61. The swing arm 64 is arranged on the damping rod 62 and is coaxially fixed with the damping rod 62.

[0044] When the stamping table 2 is vertically lowered, the toothed plate 61 contacts the contact gear 63, which swings along the coaxially fixed damping rod 62 when contacting the toothed plate 61, and drives the swing wall to swing away from the side of the stamping table 2. When the stamping table 2 is raised, the contact gear 63 and the swing arm 64 are inclined to swing towards the stamping table 2.

[0045] Referring to FIGS. 6 and 7, the deburring mechanism 6 further comprises a lubricating swing block 65, an oil hole 66, a recovery tank 67 and an oil storage pump 68; the lubricating swing block 65 is arranged on the swing arm 64, and is used to contact and lubricate the stamping table 2; the oil hole 66 is arranged on the swing arm 64, and is used to supplement the lubricating oil for the lubricating swing block 65; the recovery tank 67 is arranged on the swing arm 64 and below the oil hole 66, and the oil storage pump 68 is arranged on the swing arm 64, and is used to supplement the lubricating oil to the lubricating swing block 65 through the recovery tank 67 and the oil hole 66.

[0046] When the swing arm 64 contacts the stamping table 2, the lubricating swing block 65 can contact and lubricate the stamping table 2, and when the swing arm 64 swings away from the stamping table 2, the excess lubricating oil in the recovery tank 67 can flow back to the oil storage pump 68, thereby achieving automatic lubrication of the stamping table 2. The lubricated stamping table 2 can reduce the friction between the stamping table 2 and the workpiece when the workpiece is stamped, so that the workpiece is more smooth when it is separated, thereby avoiding burrs, and the lubricating oil can be automatically recovered.

[0047] Referring to FIGS. 6 and 7, the deburring mechanism 6 further comprises an oil tank 691, a sliding contact block 692 and a return spring 693; the oil tank 691 is arranged on the swing arm 64, and is used to supply oil to the oil storage pump 68; the sliding contact block 692 is vertically arranged in the oil storage pump 68, and is used to contact the stamping table 2; and the return spring 693 is arranged in the oil storage pump 68, and both ends of the return spring 693 are fixed to the sliding contact block 692 and the end of the oil storage pump 68.

[0048] When the oil storage pump 68 contacts the stamping table 2, the sliding contact block 692 can vertically slide downwards in the oil storage pump 68, and the return spring 693 is compressed. In this process, the sliding contact block 692 can lose the shielding of the connection between the oil storage pump 68 and the oil tank 691, so that the lubricating oil in the oil tank 691 can be supplemented into the oil storage pump 68. In this way, the lubricating oil stored in the oil storage pump 68 can be squeezed by the sliding contact block 692 and flow into the recovery tank 67, and the lubricating oil in the recovery tank 67 can flow to the lubricating swing block 65 through the oil hole 66. When the swing arm 64 is reset by tilting, the return spring 693 lifts the sliding contact block 692, and the oil storage pump 68 can recover the excess lubricating oil in the recovery tank 67 and supplement it into the oil storage pump 68.

[0049] As shown in FIG. 6 and FIG. 7, the deburring mechanism 6 further comprises an oil inlet pipe 694 and an oil outlet pipe 695; the oil inlet pipe 694 is arranged at the oil outlet end of the oil tank 691, and the oil outlet end of the oil inlet pipe 694 is connected with the oil inlet end of the oil storage pump 68; the oil outlet pipe 695 is arranged at the oil outlet end of the oil storage pump 68, and the oil outlet pipe 695 is connected with the oil inlet end of the recovery tank 67.

[0052] When the stamping table 2 rises, the rotary driver 72 is started, thereby driving the rotating roller 73 and the rotating abutting roller 74 to rotate; when the rotating abutting roller 74 contacts the workpiece and rotates, the workpiece after stamping can slide in a horizontal straight line direction, which is convenient for the next stamping work; after the stamping is completed, the rotating abutting roller 74 can automatically transport the workpiece, and manual feeding is not required.
