Description

Technical Field

[0001] The utility model belongs to the technical field of drilling of drive shaft parts, and specifically relates to a drilling tooling for drive shaft parts of a radial drilling machine. Background Art

[0002] A radial drilling machine is a drilling machine whose rocker arm can rotate and lift around a column, and usually the spindle box moves horizontally on the rocker arm. During the processing of drive shaft parts, a radial drilling machine is usually used to drill a plurality of holes equidistant from the axis in a direction parallel to the axis at positions where the cross-sectional dimensions change, such as the shaft shoulder, shaft collar on the shaft, or the flange connected to the shaft end, etc.

[0003] The Chinese patent document with the authorization announcement number CN220971437U discloses a drilling positioning tooling for a radial drilling machine, which drives a first moving block and a second moving plate to move through a first motor, and drives a second moving block and a placing plate to move through a second motor, so as to realize the movement of the placing plate on which the workpiece is clamped, so as to conveniently adjust the position of the workpiece subsequently, and thus drill holes at multiple positions of the workpiece.

[0004] However, in the prior art, although the workpiece can move, each time the workpiece is moved, it takes time to adjust the relative position between the drill hole and the workpiece to avoid deviation of the drill hole position. Therefore, a drilling tooling for drive shaft parts of a radial drilling machine is proposed. Content of the Utility Model

A clamping component is arranged on the base, which can vertically clamp the drive shaft part to be drilled and enable it to rotate horizontally. Limiting components are arranged on both sides of the clamping component, which can limit the rotation of the clamped drive shaft part during drilling.

[0008] The clamping component includes a rotating part that can place the drive shaft part to be drilled and enable it to rotate horizontally, a positioning part that can enable the operator to quickly find the drilling position, and a pressing part that can prevent the drive shaft part from moving during drilling.

[0009] Preferably: The rotating part includes a rotating frame movably installed on the base. A limiting frame is arranged between the base and the rotating frame.

[0013] Preferably, the anti-rotation rod is slidably connected to the drilling template.

[0014] Preferably, the screw rod is slidably connected to the pressing plate. Both the first nut and the second nut are threadedly connected to the screw rod.

[0015] The beneficial effects of the present utility model are as follows: By means of the rotatable rotating member and positioning member, it is convenient to vertically clamp the driving shaft part to be drilled, and the position to be drilled of the driving shaft part can be located between the rotating member and the positioning member. Subsequently, with the cooperation of the limiting assembly, the driving shaft part can be horizontally rotated by a fixed angle and subjected to drilling processing, so that it is not necessary to frequently adjust the position of the drill bit of the radial drill press, and the drilling requirements of multiple positions of the variable cross-sectional dimension part of the driving shaft part can be met.

[0025] The present invention will be further described below through embodiments in conjunction with the drawings.

[0026] As Figures 1-4 shown, a drilling tool for a drive shaft part of a radial drill press includes a base 1 that can provide an installation position for each component. A clamping assembly 2 is arranged on the base 1, which can vertically clamp the drive shaft part to be drilled and enable it to rotate horizontally. Limiting assemblies 3 are arranged on both sides of the clamping assembly 2, which can limit the rotation of the clamped drive shaft part during drilling.

[0027] In this embodiment: The clamping assembly 2 includes a rotating member for placing the drive shaft part to be drilled and enabling it to rotate horizontally, a positioning member for enabling the staff to quickly find the drilling position, and a pressing member for preventing the drive shaft part from moving during drilling. The rotating member includes a rotating frame 201 movably installed on the base 1. A limiting frame 202 is provided between the base 1 and the rotating frame 201. A lever 203 is fixedly connected to the outer side of the rotating frame 201. A jack 204 is integrally formed on the outer side of the rotating frame 201. First screw holes 205 are provided on both the base 1 and the limiting frame 202. A rotation-stopping rod 206 is fixedly connected to the upper side of the rotating frame 201. The positioning member includes a drilling template 207 provided above the rotating frame 201. A handle 208 is fixedly connected to the outer side of the drilling template 207. Positioning holes 209 are integrally formed on both the inside of the rotating frame 201 and the drilling template 207. The pressing member includes supports 210 fixedly connected to both sides of the rotating frame 201. A screw 211 is fixedly connected to the supports 210. A pressing plate 212 is movably connected to the outer side of the screw 211. A first nut 213 is provided above the pressing plate 212. A second nut 214 is provided above the first nut 213;

[0028] Both the base 1 and the limiting frame 202 are rotationally connected to the rotating frame 201. The rotation-stopping rod 206 is slidably connected to the drilling template 207. The screw 211 is slidably connected to the pressing plate 212. Both the first nut 213 and the second nut 214 are threadedly connected to the screw 211;

[0029] Place the drive shaft part to be drilled through the rotating frame 201. Limit the movable range of the rotating frame 201 on the base 1 through the limiting frame 202 to improve the stability of the horizontal rotation of the rotating frame 201. Conveniently rotate the rotating frame 201 through the lever 203. Enable the limiting assembly 3 to limit the rotation of the rotating frame 201 through the jack 204. Install bolts of the corresponding model through the first screw holes 205 to stably install the limiting frame 202 on the base 1. Limit the horizontal rotation of the drilling template 207 relative to the rotating frame 201 through the rotation-stopping rod 206. Make the drilling template 207 easy to pick up and place through the handle 208. Enable the drill bit of the radial drill to smoothly pass through the drilling template 207 and the drive shaft part located between the rotating frame 201 and the drilling template 207 through the positioning holes 209. Install the screw 211 on both sides of the rotating frame 201 through the supports 210. Jointly limit the height of the pressing plate 212 on the screw 211 through the first nut 213 and the second nut 214. Press on the rotating frame 201 and the drilling template 207 through the pressing plate 212 to improve the contact effect between the rotating frame 201 and the drilling template 207.

[0030] In this embodiment, the limit assembly 3 includes a guide plate 301 fixedly connected to the upper side of the base 1. A cylinder 302 is fixedly installed on the guide plate 301. The telescopic end of the cylinder 302 is fixedly connected to a slider 303. One side of the slider 303 is fixedly connected to a plug rod 304. Second screw holes 305 are provided on both the base 1 and the guide plate 301. The guide plate 301 is slidably connected to the slider 303. The guide plate 301 provides an installation position for the cylinder 302 and limits the movable range of the slider 303. The cylinder 302 drives the slider 303 to slide relative to the guide plate 301, so that the plug rod 304 is driven by the slider 303 to approach or move away from the insertion hole 204 on the outer side of the rotating frame 201. The plug rod 304 is inserted into the insertion hole 204 to limit the horizontal rotation of the rotating frame 201. Bolts of corresponding models are installed through the second screw holes 305 to stably install the guide plate 301 on the base 1.

[0031] Working principle: When this tooling is installed and used for drilling the drive shaft parts of a radial drill press, the drive shaft parts to be drilled are vertically placed into the rotating frame 201, and the position where the cross-sectional dimension of the drive shaft parts changes is located above the position of the positioning hole 209 integrally formed in the rotating frame 201. Then, the operator holds the handle 208 and places the drilling template 207 on the rotating frame 201 after aligning it with the anti-rotation rod 206. After placement, the pressing plate 212 is moved relative to the screw rod 211. After the pressing plate 212 is aligned with the edges of the rotating frame 201 and the drilling template 207, the first nut 213 and the second nut 214 can be rotated to apply appropriate pressure to the pressing plate 212, so that the rotating frame 201 and the drilling template 207 stably clamp the drive shaft parts.

[0032] After clamping is completed, after the cylinder 302 pushes the plug rod 304 to insert into the corresponding insertion hole 204, the operator adjusts the position of the drill bit of the radial drill press so that the drill bit can be aligned with the positioning hole 209 on one of the drilling templates 207. Then, the height of the rotating drill bit can be adjusted to drill the drive shaft parts. After drilling one hole, the cylinder 302 can be operated to separate the plug rod 304 from the rotating frame 201. Then, according to the drilling requirements, with the horizontal position of the drill bit unchanged, it is reset to a position higher than the drilling template 207. Then, the operator rotates the rotating frame 201 by a certain angle through the lever 203. After rotation is completed, the cylinder 302 is operated again to make the plug rod 304 insert into the corresponding insertion hole 204. Then, the drill bit can be lowered again to drill the drive shaft parts.

[0033] Similarly, later, with only the height of the drill bit changing, the positions where the cross-sectional dimensions of the drive shaft parts between the rotating frame 201 and the drilling template 207 change can be drilled at equal angles and equal distances in sequence.

[0034] The preferred embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those skilled in the relevant technical field.
