The current technology uses a positioning cylinder, a positioning groove, and a clamping block to achieve rapid positioning in four directions, tight clamping and better clamping effect. It does not require manual operation and achieves rapid positioning without deviation during drilling. In order to meet the drilling needs of some workpieces, the operator needs to operate the drilling equipment to tilt the workpiece for drilling. However, the device does not have a tool angle adjustment function, which limits the operator's ability to drill the workpiece.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a workpiece drilling fixture for a lathe tool post, comprising a lathe body, a drive assembly provided on one side of the top end of the lathe body, and a mounting base provided on one side of the top end of the lathe body, and an electric retraction rod provided inside the drive assembly; an adjustment mechanism is provided at the output end of the electric retraction rod, and a clamping assembly is provided on one side of the mounting base;
[0008] The adjustment mechanism includes a tool holder body located at the output end of the electric retraction rod. An installation plate is provided inside the tool holder body, and rotating rods are symmetrically installed on both sides of the installation plate. The two ends of the rotating rods are rotatably connected inside the installation plate. A housing is installed on one side of the installation plate, and a servo motor is installed inside the housing. A drill bit is installed at the output end of the servo motor. Limit boxes are symmetrically installed on the outer side of the rotating rods. A fixing tube is installed inside one end of the limit box, and a sliding rod is slidably connected inside the fixing tube. A retraction spring is sleeved on the outer side of the sliding rod, and a sliding plate is installed at one end of the sliding rod. Insert blocks are installed on one side of each sliding plate, and slots are opened on one side of each tool holder body, with the insert blocks interlocking with the slots.
[0009] Preferably, a ring-shaped scale is installed inside one side of the tool holder body, and a pointer is installed on the outer side of one end of the rotating rod.
[0010] Preferably, the clamping assembly includes a connecting plate mounted on one side of the mounting base, and a sliding box symmetrically mounted on one side of the connecting plate.

A pressing frame is installed between the movable sleeves. A worm gear is rotatably connected inside the sliding box, and a worm wheel is mounted on the outer center of the bidirectional screw. A forward and reverse motor is mounted on one end of the worm gear, and a rotating wheel is mounted on one end of the bidirectional screw. A belt is sleeved between the outer sides of the rotating wheels, and a rubber pad is mounted on the inner side of the pressing frame.
[0011] Preferably, the output end of the electric retractable rod is equipped with a fixed plate, and a rotating shaft is installed on one side of the fixed plate.

[0013] Preferably, the worm and the worm wheel are meshed together.
[0014] Preferably, one end of the drill bit cutter passes through the housing and is rotatably connected to the housing.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: A workpiece drilling fixture for a lathe tool post, specifically, involves the operator rotating a mounting plate inside the tool post body. This rotation causes changes in the angle of the mounting plate, the servo motor, and the drill bit. The operator then pulls two sets of sliding rods inside the fixed tube, causing the sliding plate to slide within the limit box. Through the restoring property of the spring, multiple sets of inserts can be engaged with the slots, enabling rapid adjustment of the fixed drill bit angle. The operator then activates the servo motor to drive the drill bit to perform tilted drilling on the workpiece. This significantly improves the flexibility of the device during use and meets the needs of various tasks. This device allows for drilling various sizes of inclined holes in workpieces without requiring workers to transfer the workpieces to other drilling equipment. The rotation of the worm gear drives the worm wheel, and the rotation of the bidirectional screw drives the rotating wheel. Through the cooperation of the rotating wheel and belt, the two sets of bidirectional screws rotate synchronously in the same direction. The movement of the moving sleeve causes the extrusion frames to move closer together. The extrusion frames then use rubber pads to press against the outer side of the workpiece, achieving rapid adjustment and fixation of the workpiece. This makes the workpiece more stable during drilling, reducing the likelihood of displacement or detachment. Compared to existing technologies using multiple cylinder drives, this method has lower operating costs and meets the needs of small workshops.
[0016] 1. The operator rotates the mounting plate inside the tool holder body. This causes the angles of the housing, servo motor, and drill bit to change. After the drill bit angle is adjusted, the operator pulls two sets of sliding rods to slide inside the fixed tube. The sliding plate slides inside the limit box, causing the spring to contract. By releasing the sliding rods and utilizing the spring's reset property, multiple sets of inserts can be inserted into the slots, achieving rapid adjustment of the drill bit angle. The operator then activates the servo motor to drive the drill bit to perform tilted drilling on the workpiece. This greatly improves the flexibility of the device and allows for drilling various sizes of tilted holes on the workpiece, eliminating the need to transfer the workpiece to other drilling devices. This enhances the device's practicality. When the operator rotates the mounting plate, the rotating rod drives the pointer to rotate. By observing the pointer and the circular scale, the operator can precisely adjust the drill bit angle, improving the drilling accuracy.
[0017] 2. The operator starts the forward and reverse motors, which drive the worm gear to rotate. The rotation of the worm gear drives the rotation of the worm wheel, which in turn drives the rotation of the bidirectional screw. The rotation of the bidirectional screw drives the rotation of the rotating wheel and the belt, thus driving the two sets of bidirectional screws to rotate synchronously in the same direction. The rotation of the bidirectional screws causes the moving sleeve to move in a convergence and unfolding trajectory. At this time, the movement of the moving sleeve causes the extrusion frames to move closer together. The extrusion frames then drive the rubber pads to press against the outside of the workpiece, thereby achieving the effect of quickly adjusting and fixing the workpiece. This makes the workpiece more stable during drilling operations and less prone to displacement or falling off. Compared with the existing technology that uses multiple sets of cylinders for driving, the operating cost is lower, meeting the needs of small workshops and bringing convenience to the operators.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-5 The present invention provides a technical solution: a workpiece drilling fixture for a lathe tool post, comprising a lathe body 1, a drive assembly 101 provided on one side of the top end of the lathe body 1, and a mounting base 102 provided on one side of the top end of the lathe body 1, and an electric retraction rod 103 provided inside the drive assembly 101; an adjustment mechanism 2 is provided at the output end of the electric retraction rod 103, and a clamping assembly 3 is provided on one side of the mounting base 102;
[0026] The adjustment mechanism 2 includes a tool holder body 201 disposed at the output end of the electric retraction rod 103. A mounting plate 202 is disposed inside the tool holder body 201, and rotating rods 203 are symmetrically mounted on both sides of the mounting plate 202. The two ends of the rotating rods 203 are rotatably connected inside the mounting plate 202. A housing 204 is mounted on one side of the mounting plate 202, and a servo motor 205 is disposed inside the housing 204. A drill rod cutter 206 is mounted at the output end of the servo motor 205, with one end of the drill rod cutter 206 penetrating through the housing 204 and rotatably connected to it. Limit boxes 207 are symmetrically mounted on the outer side of the rotating rods 203, and a fixing tube 208 is installed inside one end of the limit box 207. The fixing tube 208 has a sliding mechanism inside. The device is connected to a slide rod 209, with a retraction spring 210 sleeved on the outside of the slide rod 209. A slide plate 211 is installed at one end of the slide rod 209, and a plug block 212 is installed on one side of the slide plate 211. A slot 213 is opened on one side of the tool holder body 201, and the plug block 212 is inserted into the slot 213. This allows for quick adjustment of the angle of the fixed drill rod tool 206. At this time, the operator starts the servo motor 205 to drive the drill rod tool 206 to perform tilted drilling on the workpiece. This greatly improves the flexibility of the device during use and enables the operator to perform various sizes of tilted holes on the workpiece. It avoids the need for the operator to transfer the workpiece to other drilling devices for operation, thus bringing practicality to the operator.
[0027] An annular scale 214 is installed inside one side of the tool holder body 201, and a pointer 215 is installed on the outer side of one end of the rotating rod 203. When the operator rotates the mounting plate 202, the rotating rod 203 drives the pointer 215 to rotate. The operator can then observe the pointer 215 and the annular scale 214 to precisely adjust the angle of the drill rod tool 206, thereby improving the drilling accuracy of the workpiece. A fixing plate 216 is installed at the output end of the electric retraction rod 103, and a rotating shaft 217 is installed on one side of the fixing plate 216. The tool holder body 201 is fixedly connected to the turntable 218 via a rotatable connection. The turntable 218 and the fixed plate 216 are both threadedly connected with bolts 219. When the operator rotates the tool holder body 201, the turntable 218 rotates. At this time, the turntable 218 rotates outside the rotating shaft 217. The operator then tightens multiple sets of bolts 219, which further improves the angle adjustment range of the drill pipe tool 206, thereby making the drill pipe tool 206 more widely applicable and bringing convenience to the operator during use.
[0028] The clamping assembly 3 includes a connecting plate 301 mounted on one side of the mounting base 102, and a sliding box 302 symmetrically mounted on one side of the connecting plate 301. A bidirectional screw 303 is rotatably connected inside the sliding box 302, and movable sleeves 304 are symmetrically threaded to the outer ends of both ends of the bidirectional screw 303. A pressing frame 305 is installed between the movable sleeves 304. A worm gear 306 is rotatably connected inside the sliding box 302, and a worm wheel 307 is mounted on the outer center of the bidirectional screw 303. The worm gear 306 and the worm wheel 307 are meshed together. One end of the worm gear 306 is equipped with a forward and reverse motor 308, and one end of the bidirectional screw 303 is equipped with a rotating wheel 309. A belt 310 is sleeved between the outer sides of the rotating wheel 309, and a rubber pad 311 is installed on the inner side of the extrusion frame 305. This enables the workpiece to be quickly adjusted and fixed, making the workpiece more stable during drilling operations and less prone to displacement or falling off. Compared with the existing technology that uses multiple sets of cylinders for driving, this method has lower operating costs, meets the needs of small workshops, and brings convenience to workers.
[0029] Working principle: Before using this type of lathe tool post workpiece drilling fixture, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, the operator rotates the mounting plate 202 inside the tool holder body 201. This causes the mounting plate 202 to change the angles of the housing 204, servo motor 205, and drill bit 206. After the drill bit 206 angle is adjusted, the operator pulls two sets of sliding rods 209 to slide inside the fixed tube 208. At this time, the sliding plate 211 slides inside the limit box 207, causing the compression spring 210 to contract. By releasing the sliding rods 209 and utilizing the reset property of the compression spring 210, multiple sets of insert blocks 212 can be inserted into the slots 213, thus achieving rapid adjustment of the fixed drill bit 206 angle. The operator then activates the servo motor 205 to drive the drill bit 206 to perform tilted drilling on the workpiece, greatly improving the flexibility of the device during use and meeting the needs of the workers. This device allows operators to drill various sizes of inclined holes in workpieces, eliminating the need to transfer the workpiece to other drilling devices. This enhances practicality for operators. When the operator rotates the mounting plate 202, the rotating rod 203 drives the pointer 215 to rotate. By observing the pointer 215 and the circular scale 214, the operator can precisely adjust the angle of the drill bit 206, improving drilling accuracy. Rotating the tool holder body 201 drives the turntable 218 to rotate. The turntable 218 rotates outside the rotating shaft 217. Tightening multiple bolts 219 further expands the angle adjustment range of the drill bit 206, making its application more widespread and convenient for operators.
[0030] The operator starts the forward and reverse motor 308, which drives the worm gear 306 to rotate. The rotation of the worm gear 306 drives the worm wheel 307 to rotate, which in turn drives the bidirectional screw 303 to rotate. The rotation of the bidirectional screw 303 drives the rotating wheel 309 to rotate. Through the cooperation between the rotating wheel 309 and the belt 310, the two sets of bidirectional screws 303 rotate synchronously in the same direction. The rotation of the bidirectional screws 303 causes the moving sleeve 304 to move in a convergence and unfolding trajectory. At this time, the movement of the moving sleeve 304 causes the extrusion frame 305 to move closer together. The extrusion frame 305 then drives the rubber pad 311 to extrude on the outside of the workpiece, thereby achieving the effect of quickly adjusting and fixing the workpiece. This makes the workpiece more stable during drilling operations and less prone to displacement and falling off. Compared with the existing technology that uses multiple sets of cylinders for driving, the operating cost is lower, meeting the needs of small workshops and bringing convenience to the operators.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
