Description

Technical Field

[0001] The utility model relates to lock processing equipment, in particular to a drilling machine for processing magnetic locks. Background Art

[0002] Magnetic locks, also known as magnetic locks or electromagnetic locks, are intelligent electronic locks with high security and convenience. Magnetic locks are mainly composed of a lock body and a lock core. During the manufacturing process of the lock, it is necessary to make several holes in the lock body to facilitate the placement of the lock core. When the existing drilling machine is punching holes in the lock body, the front and back sides need to be processed step by step, that is, after punching the holes on one side, the lock body is removed from the tooling, and then the lock body is turned over to perform the punching operation on the other side. However, during the punching process, the lock body is repeatedly clamped, which is very likely to cause the problem of inaccurate positioning of the punching positions on the front and back sides due to the incorrect clamping position. For this reason, it is urgently necessary to design a punching machine that can punch holes on both sides of the lock body in one step, so as to reduce the problem of inaccurate punching position caused by repeated clamping of the lock body.

DETAILED DESCRIPTION

[0027] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0028] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figures 1-2 The drilling machine for processing magnetic locks shown in the figure comprises a workbench 100, the upper part of which has a cavity in the shape of a "mouth", in which a group of clamping devices 600 for clamping the lock body are arranged. It should be noted that the design purpose of this scheme is to realize the punching operation on the front and back sides of the lock body by one clamping. In order to realize the above operation, two rotating cylinders 800 are relatively arranged in the cavity on the workbench. The two rotating cylinders are coaxially arranged opposite to each other, and the rotating shafts of the rotating cylinders are fixedly connected to the two sides of the clamping device to drive the clamping device to turn over synchronously when the rotating cylinders rotate. It should be noted that in this scheme, after the clamping device is turned over, in order to expose the other side of the clamped lock body to facilitate the punching device on the upper part to punch holes, the main body of the clamping device 600 is in the shape of a frame that can clamp the edge of the lock body. Then the part in the middle of the lock body that needs to be punched can be exposed even after the clamping device is turned over.

[0031] In addition, it should be noted that in this solution, in order to ensure that the surface of the lock body can remain horizontal after being turned over, and that the lock body will not tilt and turn over due to the pressure of the punching device 500 when punching, two sets of locking devices 700 are relatively arranged in the chamber of the workbench. Specifically, the locking device includes a telescopic cylinder 710 that is horizontally arranged and facing the edge of the clamping device 600, and a tenon 720 is connected to the end of the telescopic cylinder. At the same time, if Figure 2 As shown, a positioning groove 611 is also provided at the edge of the clamping device, and the positioning groove is directly opposite to the tenon, and after the clamping device is flipped into place, the tenon part in the locking device 700 is inserted into the positioning groove 611 under the drive of the extended telescopic cylinder. It should be noted that in this solution, in order to facilitate the insertion of the tenon and to guide the clamping device which may be tilted to a certain extent after flipping. The tenon is in a state of a prism with a small front end and a gradually enlarged rear end, and the positioning groove on the clamping device is adapted to the shape of the tenon and has a structure that expands directly from the inside to the outside, so as to ensure that after the tenon is inserted therein, the four side walls of the tenon can respectively and smoothly abut against the groove wall of the positioning groove.

[0032] In addition, it should be noted that in this solution, in order to facilitate the fixing and clamping of the lock body, the clamping device 600 implements two fixed positioning and two-side movable clamping fixing methods. Specifically, the clamping device includes a frame-shaped clamping claw 610, the two sides of the clamping platform are respectively connected to the rotating cylinder, and positioning grooves are provided on the other two sides. At the same time, two fixed clamping strips 620 are also provided on the surface of the clamping platform. The two fixed clamping strips are arranged in parallel along the edge of the clamping platform and intersect vertically at one end. At the same time, on the frame surface of the clamping platform opposite to the side where the two fixed clamping strips 620 are located, a number of guide grooves 612 perpendicular to the corresponding fixed clamping strips are also provided at equal intervals. A movable clamping plate 650 is slidably provided in the guide groove. It should be noted that a plunger cylinder 630 is connected to the rear end of the movable clamping plate, and the plunger cylinder is connected in parallel with a pressure pump 660 installed on the clamping platform through a conduit, so that the pressure of each movable clamping plate pressing on the edge of the lock body is kept the same. It should be noted that hydraulic oil is stored in the pressure pump of the present embodiment so that the hydraulic oil can be pumped into or sucked out of the plunger cylinder when the pressure pump is running.

[0033] like Figure 2 As shown, in the present embodiment, in order to prevent relative displacement between the clamped lock body and the surface of the clamping platform, the fixed clamp bar 620 and the movable clamp plate 650 both have a bent blocking structure, that is, when the lock body is clamped, its upper and lower surfaces are clamped by the clamping platform and the fixed clamp bar and the movable clamp bar.

[0034] In addition, in this solution, the clamping of the movable clamping plate on the lock body can be adjusted. Specifically, Figure 2 As shown, a valve 640 is also provided on the entry end of the plunger cylinder. The motion state of the movable clamping plate during clamping is controlled by opening and closing the valve.

[0035] In addition, it should be noted that in this solution, the lock body has multiple punching positions, and the positions are different. In order to achieve the punching operation at each position, the punching device 500 has the ability to adjust the space. Specifically, the punching device is realized by the X-direction walking device 200, the Y-direction walking device 300 and the lifting device 400 connected thereto.

[0036] Specifically, Figure 1 The X-direction walking device includes two rotatable screw rods 210 mounted above the workbench, the two screw rods extend along the x direction, and a first motor 220 is coaxially connected to one end of the screw rod to drive the screw rod to rotate. At the same time, a screw sleeve 230 is screwed on the screw rod, and as the screw rod rotates, the screw sleeve moves axially on the screw rod. It should be noted that the Y-direction walking device is connected to the two screw sleeves to move along the x direction with the screw sleeves.

[0037] like Figure 1As shown, in the present embodiment, the Y-axis running device 300 includes a guide rail 310 straddling the top of the workbench, and the two ends of the guide rail are respectively connected to two screw sleeves. A running mechanism 320 that runs along the length direction of the guide rail is installed on the guide rail. It should be noted that the running mechanism adopted in the present embodiment adopts a basic roller structure, which has the advantages of simple structure and low cost. A lifting device 400 is installed on the running mechanism, and the lifting end of the lifting device is connected to the punching device 500 of the present embodiment, so that the drilling operation can be performed at different positions on the surface of the lock body under the drive of the X-axis running device 200, the Y-axis running device 300 and the lifting device 400. It should be noted that, as Figure 2 As shown, the drilling device in this solution is mainly composed of a second motor 500 connected to the lifting device and a drill bit 520 connected to the output shaft of the second motor.

[0038] Working principle: When it is necessary to punch holes on both sides of the lock body, the staff will place the lock body on the clamping table of the clamping device. Then the pressure pump is driven to work. After the pressure pump pumps the liquid into the plunger cylinder, the movable clamping plate pushes the lock body to the side where the fixed clamping plate on the clamping table is located under the drive of the plunger cylinder, and finally clamps the lock body with the same pressure. It should be noted that in the process of driving the movable clamping plate to extend, the staff can adjust the required movable pressure plate action by opening or closing the valve according to the shape of the edge of the lock body to achieve stable clamping of the edge of the lock body. After the above steps are completed, the staff mechanism drives the X-axis walking device 200, the Y-axis walking device 300 and the lifting device 400 to move, so that the punching device moves to the required punching position, and then drives the punching device to punch the lock body. It should be noted that when the punching of one side of the lock body is completed, the telescopic cylinder is driven to retract, the tenon of the locking device withdraws from the positioning groove of the clamping device, and then the rotary cylinder is driven to rotate so that the side of the lock body that has not been punched is flipped to the top. After the tenon is driven to be inserted into the positioning groove, the above punching steps are repeated, which is convenient and quick. In this solution, only one clamping is required for punching holes on both sides of the lock body, which avoids the problem that the original punching machine needs to be clamped twice when punching holes, and the problem of inaccurate positioning of the lock body during the secondary clamping process is avoided.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
