Description

Technical Field

[0001] This invention relates to the field of deburring machine technology, and in particular to a deburring machine for deburring workpieces by drilling holes. Background Technology

[0002] Some workpieces require the machining of round holes and oblong holes during processing. After the round holes and oblong holes are stamped, burrs will remain in them. Therefore, a deburring machine is needed to remove the burrs. Currently, in the deburring process, the round holes and oblong holes are deburred by two deburring machines, which is a two-step process. After the round holes are deburred, they are sent to another deburring machine to remove the burrs from the oblong holes. This makes the deburring efficiency low. There is an urgent need for a deburring machine that can remove burrs from oblong holes and round holes at the same time. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a deburring machine for deburring workpieces by drilling holes. This invention solves the technical problem that it is currently impossible to use a single machine to remove burrs from both oblong and round holes at the same time.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a deburring machine for deburring workpieces by drilling, comprising a base, a turntable rotatably disposed on the base, a plurality of workstations circumferentially disposed on the turntable, each workstation being provided with a tooling fixture for clamping the workpiece, a first deburring device for deburring round holes on the workpiece and a second deburring device for deburring oblong holes on the workpiece disposed on the base, the first deburring device comprising a first mounting seat disposed on the base, a first driving member disposed on the first mounting seat, and a first cutting tool disposed at the output end of the first driving member and adapted to the round hole; the second deburring device comprising a second mounting seat disposed on the base, a mounting shaft disposed on the second mounting seat, a driving device mounted on the mounting shaft via a mounting plate, and a second cutting tool disposed at the output end of the driving device, the second cutting tool being adapted to the oblong hole;

[0005] The tooling fixture includes a clamping seat mounted on a base, a fixed seat detachably mounted in the clamping seat, a positioning plate detachably mounted on the fixed seat and used for workpiece positioning, and a first clamping assembly mounted on the base for workpiece clamping.

[0006] The second cutter is a hollow tubular structure with an internal groove. A first and second receiving cavity are slidably disposed within the groove, forming a burr collection chamber. A sliding rod is disposed within the groove, with one end extending upwards outside the second cutter and the other end extending into the receiving groove. Connecting springs for connecting to the first and second receiving cavities are provided at both the upper and lower ends of the sliding rod. The surface of the second cutter has a connecting groove through which the sliding rod passes and slides. A cylinder is connected to the outer end of the sliding rod to drive its movement. A rotating shaft is rotatably disposed within the sliding rod, with one end connected to a motor driving its rotation and the other end connected to two connecting ropes. One connecting rope passes through the sliding rod and connects to the first receiving cavity, and the other connecting rope passes through the sliding rod and connects to the second receiving cavity. Sliding plates are detachably mounted on the inner walls of both the first and second receiving cavities, and these sliding plates are connected to the connecting springs and connecting ropes.

[0007] Preferably, the first clamping assembly includes a cylinder mounted on a base, a support rod mounted on the housing of the cylinder, and a pressure rod rotatably connected to the support rod. One end of the pressure rod is movably connected to the output end of the cylinder, and the bottom of the other end is provided with a pressure block for clamping the workpiece.

[0008] Preferably, the bottom of the positioning plate is provided with a positioning protrusion, and the fixing seat is provided with a positioning groove that matches the positioning protrusion.

[0009] Preferably, the top corners of the fixing base are all rounded, and at least two rounded corner structures have different radii.

[0010] Preferably, a guide rod is detachably mounted on the clamp, and the guide rod is provided with a guide hole through which the first tool can pass.

[0011] Preferably, the mounting shaft is provided with a second clamping assembly for clamping the workpiece. The second clamping assembly includes a clamp on the mounting shaft, a rodless cylinder connected to the clamp, and a pressure plate at the lower end of the rodless cylinder.

[0012] Preferably, the driving device includes a cylinder, an output shaft disposed on the cylinder and passing through the mounting shaft, and a slide connected to the output shaft. The second tool is disposed on the slide, and the mounting shaft is provided with a waist-shaped groove through which the output shaft can pass.

[0013] Preferably, the base is further provided with a power supply device, which includes a connecting rod on the base and a connecting column located in the middle of the turntable and connected to the connecting rod at its top. The connecting rod has a connecting groove, and the connecting column has a mounting groove communicating with the connecting groove. The connecting groove contains a power cord, an air inlet pipe, and an air outlet pipe. The mounting groove is further divided into a power supply groove, an air inlet groove, and an air outlet groove. The connecting column has multiple wire holes circumferentially connected to the power supply groove. The power cord passes through the connecting groove, the power supply groove, and the wire holes in sequence. The connecting column also has multiple air inlets communicating with the air inlet groove and air outlets communicating with the air outlet groove. The air inlet pipe passes through the connecting groove and communicates with the air inlet groove, and the air outlet pipe passes through the connecting groove and communicates with the air outlet groove.

[0014] In summary, the advantages of this invention compared to the prior art are as follows: the workpiece is clamped on the turntable station by a tooling fixture. First, the turntable is started, and the workpiece is moved to the first deburring position. The burrs in the round hole of the workpiece are removed by the first deburring device. Then, the turntable rotates and moves the workpiece to the second deburring device position. The burrs in the waist-shaped hole of the workpiece are removed by the second deburring position. This allows the removal of burrs from waist-shaped holes and round holes to be achieved on one machine, improving the deburring efficiency of the workpiece. Attached Figure Description

[0027] In the description of this invention, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 1This embodiment discloses a deburring machine for drilling and deburring workpiece 6, including a base 1, a turntable 2 rotatably mounted on the base 1, and multiple stations arranged circumferentially on the turntable 2. Each station is equipped with a tooling fixture 3 for clamping the workpiece 6. The base 1 is equipped with a first deburring device 4 for deburring the round hole 61 on the workpiece 6 and a second deburring device 5 for deburring the oblong hole 62 on the workpiece 6. The first deburring device 4 includes a first mounting base 41 mounted on the base 1, a first driving member mounted on the first mounting base 41, and a first cutting tool 43 mounted at the output end of the first driving member and adapted to the round hole 61. The second deburring device 5 includes a second mounting base 51 mounted on the base 1, a mounting shaft 52 mounted on the second mounting base 51, a driving device 53 mounted on the mounting shaft 52 via a mounting plate, and a second cutting tool 54 mounted at the output end of the driving device 53. The second cutting tool 54 is adapted to the oblong hole 62.

[0030] The rotation of turntable 2 is driven by a motor and belt. During the rotation, deburring of the round hole 61 and the oblong hole 62 on the workpiece 6 is performed simultaneously. The first driving component mainly drives the first cutter 43 to rotate and move, causing the first cutter 43 to insert into the round hole 61 of the workpiece 6 and remove the burrs in the round hole 61. The driving device 53 includes a cylinder, an output shaft 531 mounted on the cylinder and passing through the mounting shaft 52, and a slide 532 connected to the output shaft 531. The second cutter 54 is mounted on the slide 532. The mounting shaft 52 is provided with an oblong groove 521 through which the output shaft 531 can pass. The cylinder and the output shaft 531 drive the second cutter 54 to move, so that the second cutter 54 inserts into the oblong hole 62 of the workpiece 6 and removes the burrs in the oblong hole 62. The number of second cutters 54 is set according to the actual situation. Three first deburring devices 4 and one second deburring device 5 are provided on the entire base 1. The function of the oblong groove 521 is to facilitate the adjustment of the height of the output shaft 531 to accommodate workpieces 6 of different heights.

[0031] Reference Figures 2-5The tooling fixture 3 includes a clamping seat 31 disposed on the base 1, a fixed seat 32 detachably disposed in the clamping seat 31, a positioning plate 33 detachably disposed on the fixed seat 32 and used for positioning the workpiece 6, and a first clamping assembly 34 disposed on the base 1 for clamping the workpiece 6. The first clamping assembly 34 is used to fix the workpiece 6 on the clamping seat 31. Specifically, the first clamping assembly 34 includes a cylinder mounted on the base 1, a support rod 341 mounted on the housing of the cylinder, and a pressure rod 342 rotatably connected to the support rod 341. One end of the pressure rod 342 is movably connected to the output end of the cylinder, and the bottom of the other end is provided with a pressure block 343 for clamping the workpiece 6. After the workpiece 6 is positioned on the positioning plate 33, the cylinder drives one end of the pressure rod 342 to move upward. Under the action of the support rod 341, the other end of the pressure rod 342 drives the pressure block 343 to move downward, fixing the workpiece 6 on the positioning plate 33. The surface of the positioning plate 33 is irregularly shaped, the same as the shape of the bottom of the workpiece 6, to prevent the workpiece 6 from moving or rotating on the positioning plate 33.

[0032] The positioning plate 33 has a positioning protrusion 331 at its bottom, and the fixing seat 32 has a positioning groove 321 that matches the positioning protrusion 331. The cooperation between the positioning groove 321 and the positioning protrusion 331 prevents relative rotation between the positioning plate 33 and the fixing seat 32. The positioning plate 33, the fixing seat 32, and the clamping seat 31 are all detachable, allowing for the replacement of fixing seats 32 and positioning plates 33 of different shapes or specifications when processing different workpieces 6. The top corners of the fixing seat 32 are all rounded, and at least two of the rounded corners have different radii, ensuring that the worker will not install the fixing seat 32 in reverse during assembly (because if installed in reverse, the different sizes of the rounded corners would prevent the fixing seat 32 from fitting).

[0033] The clamp 31 is detachably equipped with a guide rod 7, which has a guide hole 71 through which the first tool 43 can pass. When the first tool 43 is working, it will pass through the guide hole 71, making the movement of the first tool 43 more stable.

[0034] Reference Figure 6 Since the first clamping device does not have a very good clamping effect during the deburring process of workpiece 6, a second clamping assembly 8 is provided on the mounting shaft 52 to clamp workpiece 6. The second clamping assembly 8 includes a clamp 81 on the mounting shaft 52, a rodless cylinder connected to the clamp 81, and a pressure plate 82 at the lower end of the rodless cylinder. The pressure plate 82 is pressed down by the rodless cylinder to clamp workpiece 6, so that workpiece 6 can be stably fixed on the positioning plate 33 during the deburring process.

[0035] Reference Figure 7 , Figure 8The base 1 is also equipped with a power supply device 9, which includes a connecting rod 91 on the base 1 and a connecting post 92 located in the middle of the turntable 2 and connected to the connecting rod 91 at its top. The connecting rod 91 has a connecting groove 911, and the connecting post 92 has a mounting groove communicating with the connecting groove 911. The connecting groove 911 contains a power cord, an air inlet pipe, and an air outlet pipe. The mounting groove is further divided into a power supply groove 921, an air inlet groove 922, and an air outlet groove 923. The connecting post 92 has multiple wire holes 9211 circumferentially arranged, communicating with the power supply groove 921. The power cord passes through the connecting groove 911, the power supply groove 921, and the wire holes 9211 in sequence. Furthermore, the connecting column 92 is also circumferentially provided with multiple air inlets 9221 communicating with the air inlet slot 922 and air outlets 9231 communicating with the air outlet slot 923. The air inlet pipe passes through the connecting slot 911 and communicates with the air inlet slot 922, and the air outlet pipe passes through the connecting slot 911 and communicates with the air outlet slot 923. The power cord, air inlet pipe, and air outlet pipe can enter the power inlet slot 921, air inlet slot 922, and air outlet slot 923 respectively from the connecting slot 911. The power cord can pass through the wire hole 9211 to supply power to the electrical equipment. The air inlet pipe and air outlet pipe are mainly used for the air intake and exhaust of the cylinder. The entire power supply device 9 realizes integrated electrical and multi-station power supply, which is convenient to use and saves the surface space of the turntable 2.

[0036] Reference Figures 9-11The second cutter 54 is a hollow tubular structure with an internal groove 541. A first receiving cavity 10 and a second receiving cavity 11 are slidably disposed within the groove 541, forming a receiving cavity for collecting burrs. A sliding rod 12 is disposed within the groove 541, with one end extending upwards outside the second cutter 54 and the other end extending into the receiving groove. Connecting springs 13 are provided at both the upper and lower ends of the sliding rod 12 for connecting to the first receiving cavity and the second receiving cavity 11. The surface of the second cutter 54 has a connecting groove 542 through which the sliding rod 12 passes and slides. 2. An external cylinder is connected to drive its movement. A rotating shaft 14 is rotatably installed inside the slide rod 12. One end of the rotating shaft 14 is connected to a motor that drives its rotation, and the other end is connected to two connecting ropes 15. One connecting rope 15 passes through the slide rod 12 and is connected to the first receiving cavity 10, and the other connecting rope 15 passes through the slide rod 12 and is connected to the second receiving cavity 11. The inner walls of both the first receiving cavity 10 and the second receiving cavity 11 are slidably and detachably equipped with sliding plates 16. The sliding plates 16 are connected to the connecting spring 13 and the connecting ropes 15. Because there are many burrs in the waist-shaped hole 62, after the second cutter 54 removes the burrs in the waist-shaped hole 62, the burrs will enter the workpiece 6 and fall onto the positioning plate 33. Because it is difficult to clean, when the second workpiece 6 moves to the designated position towards the oblong hole 62, before the second cutter 54 enters the oblong hole 62, the cylinder will first drive the slide rod 12 to move, and then drive the first receiving cavity 10 and the second receiving cavity 11 to slide out of the slide groove 541 and slide into the inside of the oblong hole 62. Then the motor drives the rotating shaft 14 to rotate, so that the two connecting ropes 15 are released. Under the action of the connecting spring 13, the first receiving cavity 10 and the second receiving cavity 11 expand to both sides, wrapping the oblong hole 62 (at this time, the sides of the first receiving groove and the second receiving groove are against the inner wall of the workpiece 6, so the left side of the first receiving cavity 10 and the second receiving cavity 11 is made of sponge or other materials, so that...). The first receiving cavity 10 and the second receiving cavity 11 can abut against the inner wall of the workpiece 6. When the second cutter 54 enters the waist-shaped hole 62, the removed burrs will be collected in the receiving cavity. After the burrs are removed, the motor rotates in the opposite direction, and then the cylinder pulls back, causing the first receiving cavity 10 and the second receiving cavity 11 to retract and slide into the slide groove 541. Then the second cutter 54 resets, completing the removal and collection of burrs, which is convenient for cleaning burrs. When it is necessary to remove the burrs in the receiving cavity, the slider can be directly slid down from the first receiving cavity 10 and the second receiving cavity 11. In this way, the first receiving cavity 10 and the second receiving cavity 11 can be disassembled and the burrs inside can be cleaned, which is very convenient to use.

[0037] Working principle: The workpiece 6 to be deburred is placed on the positioning plate 33 of the tooling fixture 3 and clamped and fixed by the pressure rod 342 and the pressure block 343. Then, the turntable 2 is driven to rotate, moving the workpiece 6 to the designated position. Then, the rodless cylinder drives the pressure plate 82 to clamp the workpiece 6 again. Then, the first deburring device 4 and the second deburring device 5 are started simultaneously. The first cutter 43 removes the burrs in the round hole 61, and the second cutter 54 removes the burrs in the oblong hole 62. This allows the removal of burrs from the oblong hole 62 and the round hole 61 to be achieved on one machine, improving the deburring efficiency of the workpiece 6. During the process of the second cutter 54 removing burrs, the burrs in the oblong hole 62 are collected by the collection cavity for easy cleaning.
