Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to an instrument lathe capable of precision machining. Background Technology

[0002] An instrument lathe is a small horizontal lathe primarily used for machining workpieces with a diameter of less than 250mm. It is typically mounted on a wooden or iron worktable and uses a small three-jaw chuck or spring collet to hold the workpiece. Instrument lathes are characterized by their small size and light weight. Furthermore, they can be automated by adding automatic feeding mechanisms or pneumatic feeding and clamping mechanisms. Widely used in the hardware and machinery processing industry, instrument lathes can machine parts of various shapes, including external diameters, internal diameters, cut-off sections, and end faces.

[0003] Currently, a type of workpiece such as Figure 1 As shown, the device includes a sleeve and a connecting part located at the bottom of the sleeve. When an existing instrument lathe needs to process a workpiece, it is necessary to first clamp and fix the workpiece with a three-jaw chuck before processing the workpiece.

[0004] In the above solution, since the workpiece is hollow and has a thin wall, directly using a three-jaw chuck to clamp and fix the workpiece can easily damage it, thus affecting the quality of the workpiece. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an instrument lathe that can be precisely machined. By providing a fixing component, it ensures that the workpiece will not be damaged when it is fixed, thus solving the problem that the workpiece is easily damaged when it is clamped and fixed in the prior art, and thus not affecting the quality of the workpiece.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A precision-machining instrument lathe includes a frame, a drive unit inside the frame, a transmission box and a transverse moving device at the upper end of the frame, a three-jaw chuck mounted on the side wall of the transmission box, a forward and backward moving device on the transverse moving device, a worktable on the forward and backward moving device, an adjustable block that can move up and down at the upper end of the worktable, a rotatable grinding wheel on the side wall of the adjustable block, and a fixing component for fixing the workpiece inside the three-jaw chuck.

[0008] When a workpiece needs to be processed, the fixing component is placed in the three-jaw chuck, and then the three-jaw chuck is activated to clamp and fix the fixing component. The workpiece is then placed in the fixing component, which positions and fixes the workpiece in the required position, ensuring that the workpiece is not damaged during fixing and thus ensuring that the quality of the workpiece is not affected. Then, the drive device is activated, which drives the three-jaw chuck to rotate through the transmission box. The rotation of the three-jaw chuck drives the fixing component to rotate, and the rotation of the fixing component drives the workpiece to rotate. Then, the transverse moving device is activated, which drives the forward and backward moving device and the worktable to move to the left, so that the grinding wheel is against the end of the workpiece. Since the grinding wheel is rotatable, when the grinding wheel is against the end of the workpiece, it will drive the grinding wheel to rotate together. There is a certain speed difference between the grinding wheel and the workpiece during the rotation, so the workpiece can be ground by the grinding wheel. Then, the forward and backward moving device drives the worktable to move back and forth, which drives the adjusting block to move back and forth, and then moves the adjusting block up and down to the required position as needed, so that the workpiece can be ground at the required position.

[0009] By incorporating a fixing component, the workpiece is protected from damage during clamping, thus solving the problem of workpiece injury during clamping and fixing in existing technologies and ensuring that the quality of the workpiece is not affected.

[0010] The utility model is further configured such that: the adjustable block that can move up and down includes a guide rod fixed to the upper end of the worktable, the adjustable block is inserted into the side wall of the guide rod, a screw is screwed into the adjustable block, the screw passes through the protruding end of the adjustable block and is rotatably connected to the upper end of the worktable, and a pressing component is provided at the upper end of the screw.

[0011] With the above technical solution, when it is necessary to move the adjusting block up and down, the screw is rotated, which can move the adjusting block up and down. After the adjusting block is moved up and down to the required position, the screw is fixed by the pressing component, so that the screw cannot rotate. This can fix the adjusting block in the required position and ensure that the adjusting block will not deviate during the processing of the workpiece.

[0012] The utility model is further configured such that: the pressing component includes a connecting rod fixed to the upper end of the screw, a screw is screwed into the connecting rod, and the screw passes through the protruding end of the connecting rod and presses against the upper end of the worktable.

[0013] With the above technical solution, when it is necessary to fix the screw, rotate the screw so that the end of the screw presses against the upper end of the worktable, thereby fixing the screw.

[0014] The utility model is further configured such that: the rotatable grinding wheel includes a rotating shaft rotatably connected to the side wall of the worktable, a support rod is screwed to the end of the rotating shaft, the grinding wheel is inserted into the side wall of the support rod, and a nut is screwed to the end of the support rod.

[0015] With the above technical solution, when it is necessary to install a grinding wheel of the required specifications, the support rod of the required specifications is screwed to the end of the rotating shaft, the grinding wheel of the required specifications is inserted into the side wall of the support rod, and then the nut is screwed to the end of the support rod, so that one end of the grinding wheel abuts against the end of the rotating shaft and the other end of the grinding wheel abuts against the side wall of the nut, thereby fixing the grinding wheel.

[0016] The utility model is further configured such that: the fixing component includes a clamping column, a positioning column is fixed at the end of the clamping column, a positioning groove that mates with the workpiece is formed on the side wall of the positioning column, and a bolt is screwed to the bottom of the positioning groove.

[0017] With the above technical solution, when it is necessary to fix the workpiece in the required position, the workpiece is inserted into the positioning groove and the end of the workpiece abuts against the side wall of the positioning column, thereby positioning the workpiece. Then, the bolt is inserted into the workpiece and screwed through the protruding end of the workpiece to the bottom of the positioning groove, while the end of the bolt is pressed against the bottom of the workpiece, thereby fixing the workpiece in the required position.

[0018] The beneficial effects of this utility model are:

[0019] Compared with existing technologies, by incorporating a fixing component, the workpiece is protected from damage during clamping, thus solving the problem that existing technologies easily damage workpieces when clamping and fixing them, and therefore does not affect the quality of the workpiece.

Detailed Implementation

[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0026] The following is for reference Figures 1 to 4 This utility model will now be described.

[0027] A precision-machining instrument lathe includes a frame 1, a drive unit 2 inside the frame 1, a transmission box 3 and a transverse moving device 4 at the upper end of the frame 1, a three-jaw chuck 5 mounted on the side wall of the transmission box 3, a front-rear moving device 6 mounted on the transverse moving device 4, a worktable 7 mounted on the front-rear moving device 6, an adjustable block 8 that can move up and down at the upper end of the worktable 7, a rotatable grinding wheel 9 mounted on the side wall of the adjustable block 8, and a fixing component for fixing the workpiece inside the three-jaw chuck 5.

[0028] When processing a workpiece, the fixing component is placed in the three-jaw chuck 5, and then the three-jaw chuck 5 is activated to clamp and fix the fixing component. The workpiece is then placed inside the fixing component, thus positioning and fixing it in the desired position while ensuring that the workpiece is not damaged during fixing, thereby ensuring that the workpiece quality is not affected. Next, the drive device 2 is activated, which drives the three-jaw chuck 5 to rotate via the transmission box 3. The rotation of the three-jaw chuck 5 drives the fixing component to rotate, which in turn drives the workpiece to rotate. Finally, the lateral movement device 4 is activated, carrying... The forward and backward moving device 6 and the worktable 7 move to the left, so that the grinding wheel 9 abuts against the end of the workpiece. Since the grinding wheel 9 is rotatable, when the grinding wheel 9 abuts against the end of the workpiece, it will drive the grinding wheel 9 to rotate together. There is a certain speed difference between the grinding wheel 9 and the workpiece during the rotation. Thus, the workpiece can be ground by the grinding wheel 9. Then, the forward and backward moving device 6 drives the worktable 7 to move back and forth. The forward and backward moving of the worktable 7 drives the adjusting block 8 to move back and forth. As needed, the adjusting block 8 moves up and down to the required position, so that the workpiece can be ground at the required position.

[0029] By incorporating a fixing component, the workpiece is protected from damage during clamping, thus solving the problem of workpiece injury during clamping and fixing in existing technologies and ensuring that the quality of the workpiece is not affected.

[0030] The adjustable block 8 that can move up and down includes a guide rod 10 fixed to the upper end of the worktable 7. The adjustable block 8 is inserted into the side wall of the guide rod 10. A screw rod 11 is screwed into the adjustable block 8. The screw rod 11 passes through the protruding end of the adjustable block 8 and is rotatably connected to the upper end of the worktable 7. A pressing component is provided at the upper end of the screw rod 11.

[0031] When it is necessary to move the adjusting block 8 up and down, rotate the screw 11 to move the adjusting block 8 up and down. After the adjusting block 8 is moved up and down to the required position, the screw 11 is fixed by the pressing component so that the screw 11 cannot rotate. This fixes the adjusting block 8 in the required position and ensures that the adjusting block 8 will not deviate during the processing of the workpiece.

[0032] The pressing assembly includes a connecting rod 12 fixed to the upper end of the screw 11, and a screw 13 is screwed into the connecting rod 12. The screw 13 passes through the protruding end of the connecting rod 12 and presses against the upper end of the worktable 7.

[0033] When it is necessary to fix the screw 11, rotate the screw 13 so that the end of the screw 13 presses against the upper end of the worktable 7, thereby fixing the screw 11.

[0034] The rotatable grinding wheel 9 includes a rotating shaft 14 rotatably connected to the side wall of the worktable 7. A support rod 15 is screwed to the end of the rotating shaft 14. The grinding wheel 9 is inserted into the side wall of the support rod 15. A nut 16 is screwed to the end of the support rod 15.

[0035] When the required size of the grinding wheel 9 needs to be installed, screw the required size of the support rod 15 to the end of the rotating shaft 14, insert the required size of the grinding wheel 9 into the side wall of the support rod 15, and then screw the nut 16 to the end of the support rod 15, so that one end of the grinding wheel 9 abuts against the end of the rotating shaft 14 and the other end of the grinding wheel 9 abuts against the side wall of the nut 16, thereby fixing the grinding wheel 9.

[0036] The fixing assembly includes a clamping post 17, a positioning post 18 is fixed to the end of the clamping post 17, a positioning groove 1801 that mates with the workpiece is formed on the side wall of the positioning post 18, and a bolt 19 is screwed to the bottom of the positioning groove 1801.

[0037] When it is necessary to fix the workpiece in the required position, insert the workpiece into the positioning groove 1801 and make the end of the workpiece abut against the side wall of the positioning post 18 to position the workpiece. Then, insert the bolt 19 into the workpiece and make the bolt 19 pass through the protruding end of the workpiece and screw it into the bottom of the positioning groove 1801. At the same time, make the end of the bolt 19 press against the bottom of the workpiece to fix the workpiece in the required position.

[0038] Working principle:

[0039] When machining a workpiece is required, the clamping column 17 is placed in the three-jaw chuck 5, and then the three-jaw chuck 5 is activated to clamp and fix the clamping column 17. The workpiece is then inserted into the positioning slot 1801, with its end abutting against the side wall of the positioning column 1801, thus positioning the workpiece. Next, the bolt 19 is inserted into the workpiece, passing through the protruding end of the workpiece and screwed into the bottom of the positioning slot 1801, with the end of the bolt 19 pressing against the bottom of the workpiece, thus fixing the workpiece in the desired position. Then, the drive device 2 is activated, driving the three-jaw chuck 5 to rotate via the transmission box 3. The rotation of the three-jaw chuck 5 causes the clamping column 17 to rotate, which in turn causes the workpiece to rotate. Finally, the transverse movement device 4 is activated. The forward and backward moving device 6 and the worktable 7 are moved to the left, so that the grinding wheel 9 abuts against the end of the workpiece. Since the grinding wheel 9 is rotatable, when the grinding wheel 9 abuts against the end of the workpiece, it will rotate together with the workpiece. There is a certain speed difference between the grinding wheel 9 and the workpiece during the rotation, so the workpiece can be ground by the grinding wheel 9. Then, the forward and backward moving device 6 drives the worktable 7 to move back and forth. The forward and backward moving of the worktable 7 drives the adjusting block 8 to move back and forth. Then, the screw 11 is rotated, so that the adjusting block 8 can move up and down. After the adjusting block 8 is moved up and down to the desired position, the screw 13 is rotated, so that the end of the screw 13 presses against the upper end of the worktable 7, thereby fixing the screw 11, so that the workpiece can be ground at the desired position.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
