Based on the embodiments in 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.

[0025] like Figure 1-Figure 3 As shown, the technical solution adopted by the utility model is as follows: a keyway machine tool for parts processing includes a frame 1, and a platform 5 is arranged on the frame 1. A cylinder 4 is fixedly connected between the bottom of the frame 1 and the platform 5, the bottom end of the cylinder 4 is fixedly connected to the frame 1, and the top of the piston rod at the output end of the cylinder 4 is fixedly connected to the platform 5.

[0026] Four telescopic rods 2 are fixedly connected between the bottom of the frame 1 and the platform 5. The bottom ends of the telescopic rods 2 are fixedly connected to the frame 1 through bolts 3, and the telescopic ends of the telescopic rods 2 are fixedly connected to the bottom surface of the platform 5. The four telescopic rods 2 are respectively located at the four corners of the bottom of the platform 5.

[0027] The platform 5 is provided with a clamping assembly for clamping parts.

[0028] The clamping assembly includes two clamping plates 8. A receiving groove 22 is provided inside the platform 5, and two slide grooves 21 are provided on the upper surface of the platform 5, and the slide grooves 21 are both connected to the receiving groove 22. The two slide grooves 21 are respectively located at the two ends of the receiving groove 22, and the middle parts of the two clamping plates 8 slide through the corresponding slide grooves 21, and the bottom ends of the clamping plates 8 are both rotatably connected to the inside of the receiving groove 22. The top end of the clamping plate 8 is located above the platform 5, so that the parts can be clamped by the top end of the clamping plate 8.

[0029] The first motor 6 is fixedly connected to the middle of the receiving groove 22. The first motor 6 is arranged horizontally and is a double-output shaft motor. The two output shafts at the left and right ends of the first motor 6 are fixedly connected to the screw rods 7, and the other end of the screw rods 7 is rotatably connected to the side wall of the corresponding receiving groove 22. The threaded sections on the two screw rods 7 have opposite rotation directions, and the bottom ends of the clamping plates 8 are respectively threadedly sleeved on the corresponding screw rods 7.

[0030] The two screw rods 7 are driven to rotate synchronously by the first motor 6 , so that the clamping plates 8 slide toward or away from each other on the receiving groove 22 .

[0031] A dust collecting box 17 is fixedly connected to the frame 1, and connecting pipes 19 are fixedly connected to the corresponding two sides of the dust collecting box 17. One end of the connecting pipe 19 is fixedly connected to a dust collecting plate 20, and the two dust collecting plates 20 are symmetrically fixedly connected to the top of the platform 5. The two dust collecting plates 20 correspond to each other front and back, and the two clamping plates 8 correspond to each other left and right.

[0032] The connecting pipe 19 is a hose, and buckles 9 are fixedly connected to both sides of the platform 5, and the connecting pipe 19 is respectively clamped on the corresponding buckles 9. It is convenient for the connecting pipe 19 to move with the platform 5.

[0033] The drill bit 16 and the connecting rod 14 are arranged on the top of the platform 5 in a rotational manner from left to right. The first motor 6 and the drill bit 16 correspond to each other up and down. Since the first motor 6 is located in the middle of the receiving groove 22, the clamping plate 8 will fix the parts just above the first motor 6, so that the drill bit 16 can process the parts.

[0034] The front and rear cross-section of the frame 1 is C-shaped, and the frame 1 is composed of an upper horizontal plate, a vertical plate, and a lower horizontal plate. The upper horizontal plate is fixedly connected to one side of the top of the vertical plate, and the lower horizontal plate is fixedly connected to one side of the bottom of the vertical plate, and the upper horizontal plate and the lower horizontal plate correspond to each other up and down.

[0035] The top end of the drill bit 16 rotates and penetrates the upper horizontal plate, the top of the upper horizontal plate is fixedly connected to the second motor 10 , and the top end of the drill bit 16 is fixedly connected to the output end of the second motor 10 .

[0036] The drill bit 16 is provided with a transmission assembly, and the transmission assembly drives the connecting rod 14 to rotate.

[0037] The transmission assembly includes a belt 12. The top of the connecting rod 14 is rotatably connected to the bottom surface of the upper horizontal plate, and a second pulley 13 is fixedly sleeved on the outer surface of the connecting rod 14. A first pulley 11 is fixedly sleeved on the outer surface of the drill bit 16, and the belt 12 is transmission sleeved on the first pulley 11 and the second pulley 13.

[0039] A filter screen is fixedly connected to the inside of the exhaust hole, and the connecting rod 14 rotates to penetrate the filter screen. After the dust generated during the processing is sucked into the inside of the dust collecting box 17, the gas will be discharged through the exhaust hole, and the filter screen will filter the dust and collect the dust in the dust collecting box 17.

[0040] The dust box 17 is fixedly passed through the vertical plate, and a through hole is provided at one end of the dust box 17 connected to the vertical plate, and a baffle 18 is detachably installed inside the through hole. After the dust box 17 is used for a period of time, the baffle 18 can be disassembled to clean the dust in the dust box 17.

[0041] Working principle:

[0042] When in use, the parts to be processed are placed on the top of the platform 5 , between the two clamping plates 8 , and between the two dust collecting plates 20 .

[0043] The first motor 6 is started, and the output shaft of the first motor 6 rotates forward, causing the two screws 7 to rotate. Since the threaded sections on the two screws 7 rotate in opposite directions, the bottom ends of the two clamping plates 8 slide inside the receiving groove 22 toward the side close to the first motor 6. The middle of the clamping plates 8 slides in the corresponding sliding groove 21, causing the two clamping plates 8 to approach each other until the parts are clamped.

[0044] The second motor 10 is started to drive the drill bit 16 to rotate. The first pulley 11 is rotated, and the second pulley 13 is rotated through the belt 12, so that the connecting rod 14 is rotated. The fan blades 15 are driven to rotate, and the fan blades 15 generate suction at the exhaust hole. The external air enters the dust box 17 through the dust suction plate 20 and the connecting pipe 19. The gas in the dust box 17 is discharged through the exhaust hole, and the filter screen will filter the gas, leaving dust and other impurities in the dust box 17.

[0045] When the cylinder 4 is started, the piston rod at the output end of the cylinder 4 pushes the platform 5 upward, so that the telescopic rod 2 is extended, and the parts are driven to move upward, so that the parts gradually come into contact with the drill bit 16 for processing, and during the processing, the dust box 17 will absorb the dust generated by the processing into the dust box 17 through the connecting pipe 19 and the dust suction plate 20.

[0046] After the processing is completed, the second motor 10 is turned off, the drill bit 16 and the fan blade 15 stop rotating, and the piston rod at the output end of the cylinder 4 pulls the platform 5 downward to shorten the telescopic rod 2. The parts leave the drill bit 16.

[0047] The first motor 6 is started, and the output shaft of the first motor 6 is reversed, so that the two clamping plates 8 move away from each other until the clamping plates 8 leave the parts, and the parts can be taken out.

[0048] After using for a period of time, the baffle 18 can be opened to clean the dust inside the dust box 17.

[0049] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
