Description

Technical Field

[0001] The present application relates to the field of plate processing, and in particular to a lubrication and cooling device for punching holes in end plates. Background Art

[0002] Punching is currently a common processing technology, which is used to process holes in metal sheet workpieces. During the punching process, a large amount of heat is generated due to high-speed impact and plastic deformation of the metal, causing the temperature of the drill bit to rise, which can easily damage the drill bit. Therefore, a cooling device is usually set on the machine body to cool the drill bit.

[0003] The existing cooling device usually uses lubricating coolant for cooling, and a nozzle is externally connected to the machine body, and the nozzle is used to spray the coolant onto the drill bit.

[0004] The above-mentioned prior art solutions have the following defects: the position of the nozzle is fixed, and when the machine body processes workpieces with different thicknesses and different drilling positions, the nozzle cannot accurately correspond to the drill position, resulting in poor lubricating coolant spraying effect. Utility Model Content

[0005] In order to improve the spraying effect of the lubricating coolant in the nozzle on the drill bit when punching different workpieces, the present application provides a lubricating and cooling device for punching an end plate.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A lubrication and cooling device for punching an end plate comprises a nozzle and an adjusting device arranged on a working surface of a machine body, wherein the adjusting device is fixedly connected to the machine body, the adjusting device is fixedly connected to the nozzle, and the adjusting device is used to adjust the relative position of the nozzle and a drill bit on the machine body; the adjusting device comprises a telescopic device, and the telescopic device is used to control the relative position relationship between the nozzle and the drill bit, the telescopic device comprises a sleeve, an inner rod and a locking structure, one end of the sleeve is fixedly connected to the working surface, the other end of the sleeve is sleeved outside the inner rod, the inner rod is slidably connected to the sleeve, the end of the inner rod away from the working surface is fixedly connected to the nozzle, and the locking structure is used to lock the relative position between the inner rod and the sleeve.

[0008] By adopting the above scheme, a sleeve is fixedly connected to the working surface, and an inner rod is inserted into the end of the sleeve away from the working surface, so that the inner rod is slidably connected in the sleeve, and the end of the inner rod away from the working surface is used to clamp the nozzle. When the drill bit punches the workpiece, the position of the drill bit is different due to the different positions of the punching holes. At this time, the inner rod is adjusted, and the inner rod slides along the sleeve, and the inner rod drives the nozzle to move until the nozzle and the drill bit are adjusted to correspond to each other. Then the locking structure is pushed, and the locking structure locks the inner rod and the outer rod. Through the above settings, the spraying effect of the nozzle on the drill bit is improved when punching different workpieces.

[0009] Furthermore, the locking structure includes a locking block and an elastic member, a groove is provided on the inner rod, one end of the elastic member is fixedly connected to the bottom wall of the groove, and the end of the elastic member away from the groove is fixedly connected to the locking block; a plurality of locking grooves are provided on the sleeve, and when the locking block is plugged into the locking groove, the relative position relationship between the inner rod and the sleeve is locked.

[0010] By adopting the above scheme, when adjusting the position relationship between the drill bit and the nozzle, the inner rod is pulled and the inner rod slides along the sleeve. In the process of the inner rod sliding along the inside of the sleeve, the elastic part is subjected to the pressure of the sleeve wall, and the elastic part is forced to shrink. When the locking block corresponds to the position of the locking groove, the force on the elastic part disappears, and the elastic part rebounds under its own elastic action. The elastic part pushes the locking block to engage with the locking groove, thereby completing the locking of the relative position of the inner rod and the sleeve.

[0011] Furthermore, a slide groove is provided on the inner rod, and the sleeve is provided with the same slide groove corresponding to the inner rod. A pulling rod is fixedly connected to one end of the locking block close to the spring, and the other end of the pulling rod passes through two slide grooves. The pulling rod is used to control the positional relationship between the locking block and the groove.

[0012] By adopting the above scheme, a pulling rod is fixedly connected to one end of the locking block, and sliding grooves are provided on the inner rod and the sleeve. When adjusting the relative position between the inner rod and the sleeve, the pulling rod is pulled toward the end close to the elastic member, and the elastic member contracts due to the pressure of the locking rod. The locking block moves into the groove due to the contraction force of the elastic member. At this time, when the inner rod slides relatively along the sleeve, the pulling rod moves along the sliding groove. When the positions of the inner rod and the sleeve are relatively determined, the pulling rod is released, the force on the elastic member disappears, and the elastic member rebounds under the action of its own elasticity. The elastic member drives the locking block to move in the direction away from the groove until the locking block is engaged with the locking groove.

[0013] Furthermore, a pulling ring is fixedly connected to one end of the pulling rod away from the locking block, and the pulling ring is fixedly connected to the pulling rod.

[0014] By adopting the above solution, a pulling ring is fixedly connected to the side of the pulling rod away from the locking block. When the pulling rod is pulled, the setting of the pulling ring facilitates pulling the pulling rod.

[0015] Furthermore, the adjusting device also includes a lifting device, which includes a fixed rod, a lifting rod and a stop rod, one end of the fixed rod is fixedly connected to the working surface, and a lifting groove is opened at the end of the fixed rod away from the working surface. One end of the lifting rod is inserted into the lifting groove, the lifting rod is slidingly connected to the lifting groove, and the end of the lifting rod away from the working surface is fixedly connected to the telescopic device, the stop rod passes through the side wall of the lifting groove and abuts against the lifting rod, and the stop rod is threadedly connected to the sleeve.

[0016] By adopting the above scheme, when the machine body processes workpieces of different thicknesses, the position of the drill bit is different, so a lifting device is set up. By adjusting the lifting rod, the lifting rod slides along the lifting groove until the lifting member drives the telescopic rod to a height corresponding to the drill bit position, and the telescopic rod drives the nozzle to correspond to the drill bit position. At this time, the setting rod is rotated until the stop rod abuts against the lifting rod, thereby completing the locking of the relative position of the lifting rod and the sleeve.

[0017] Furthermore, the adjusting device also includes an articulation device, which includes an articulation ball, an articulation block and a top screw. The articulation block is rotatably connected to the end of the lifting rod away from the working surface. The side wall of the articulation block is provided with an articulation groove. The articulation ball is articulated in the articulation groove. The articulation ball is fixedly connected to the end of the sleeve away from the nozzle. The top screw is threadedly connected to the side wall of the articulation groove. When the relative position of the articulation ball and the articulation groove is determined, the top screw passes through the side wall of the articulation groove and abuts against the articulation ball.

[0018] By adopting the above scheme, an articulated block is rotatably connected to the end of the lifting rod away from the working surface, and then an articulated groove is opened on the side wall of the articulated block. An articulated ball is articulated in the articulated groove. Since the articulated ball is fixedly connected to one end of the sleeve, the articulated ball rotates in the articulated groove, driving the position of the sleeve until the sleeve is displaced, driving the position of the inner rod. The displacement of the inner rod drives the position of the nozzle clamped by the inner rod until the positions of the nozzle and the drill bit correspond. The top screw is rotated, and the top screw passes through the side wall of the articulated groove and abuts against the articulated ball, thereby completing the locking of the nozzle position.

[0019] Furthermore, one end of the inner rod away from the working surface is fixedly connected to a clamping structure, and the clamping structure is used to clamp the nozzle.

[0020] Furthermore, the clamping structure includes a first clamping member, a second clamping member and a spring. The first clamping member and the second clamping member are hingedly arranged, the hinge shaft is fixedly connected to the inner rod, the spring is arranged between the first clamping member and the second clamping member, the two ends of the spring are respectively fixedly connected to the tail ends of the first clamping member and the second clamping member, and the end of the first clamping member and the second clamping member away from the spring is used to clamp the nozzle.

[0021] By adopting the above scheme, when using the clamping structure, the tail ends of the first clamping member and the second clamping member are pressed against each other, the nozzle is placed on the end of the first clamping member and the second clamping member away from the spring, and the first clamping member and the second clamping member are released. The spring rebounds under the action of its own elasticity, driving the end of the first clamping member and the second clamping member away from the spring to approach each other, thereby clamping the nozzle.

[0022] In summary, this application has the following technical effects:

[0023] 1. By setting an adjustment device, a sleeve is fixedly connected to the working surface, and an inner rod is inserted into the end of the sleeve away from the working surface, so that the inner rod is slidably connected in the sleeve, and the end of the inner rod away from the working surface is used to clamp the nozzle. When the drill bit punches the workpiece, the position of the drill bit is different due to the different positions of the punching holes. At this time, the inner rod is adjusted, and the inner rod slides along the sleeve, and the inner rod drives the nozzle to move until the nozzle and the drill bit are adjusted to correspond to each other, and then the locking structure is pushed, and the locking structure locks the inner rod and the outer rod. Through the above settings, the spraying effect of the nozzle on the drill bit is improved when punching different workpieces;

[0024] 2. By setting a lifting device, when the machine body processes workpieces of different thicknesses, the position of the drill bit is different, so a lifting device is set, and by adjusting the lifting rod, the lifting rod slides along the lifting slot until the height of the lifting member drives the telescopic rod to correspond to the position of the drill bit, and the telescopic rod drives the nozzle to correspond to the position of the drill bit. At this time, the setting rod is rotated until the stop rod abuts against the lifting rod, thereby completing the locking of the relative position of the lifting rod and the sleeve;

[0025] 3. A pulling rod is provided, a pulling rod is fixedly connected to one end of the locking block, and sliding grooves are provided on the inner rod and the sleeve. When adjusting the relative position between the inner rod and the sleeve, the pulling rod is pulled toward the end close to the elastic member, and the elastic member contracts due to the pressure of the locking rod. The locking block moves into the groove due to the contraction force of the elastic member. At this time, when the inner rod slides relatively along the sleeve, the pulling rod moves along the sliding groove. When the positions of the inner rod and the sleeve are relatively determined, the pulling rod is released, the force on the elastic member disappears, and the elastic member rebounds under its own elastic action. The elastic member drives the locking block to move in the direction away from the groove until the locking block is engaged with the locking groove. BRIEF DESCRIPTION OF THE DRAWINGS
