Description

Technical Field

[0001] The utility model relates to the technical field of tool processing, in particular to a tool edge processing device. Background Technique

[0002] When the cutting deformation and cutting force of a tool decrease, in order to enhance the strength of the cutting edge, a chamfered edge is usually ground on the rake face with a positive rake angle of the tool. The chamfered edge improves the distribution of the cutting force, increases the rigidity of the tool edge, and improves the cutting performance of the tool; at the same time, it reduces the wear and damage of the tool and prolongs the service life of the tool. Therefore, it is particularly necessary to improve the processing quality of the tool chamfered edge.

[0003] The tool mounting table of the existing tool edge processing device is used for clamping the tool. However, limited by the existing technical level, the existing tool mounting table adopts a vertical design, the center line of the tool rest is perpendicular to the workbench, and the grinding wheel is placed above the tool mounting table. It is difficult to machine all the chamfered edges in one clamping. During the processing, the tool needs to be manually clamped on the tool mounting table multiple times, and the grinding wheel can grind out all the chamfered edges through multiple discontinuous processes, resulting in a joint printing problem for the chamfered edges machined after each clamping. Moreover, frequently clamping the tool also takes time and effort, seriously affecting the processing quality and efficiency of the tool chamfered edge. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tool edge processing device, which adopts a horizontal design and solves the technical problems of low processing quality and low processing efficiency of the existing tool chamfered edge.

[0024] A longitudinal distance measuring assembly, which is fixedly disposed on the support table and is used to measure the longitudinal distance between the tool and the grinding wheel along the third direction;

[0025] A control assembly, which is respectively connected to the longitudinal distance measuring assembly and the pitching driving member, and is used to control the pitching driving member to drive the grinding wheel to act along the third direction to adjust the longitudinal distance when the longitudinal distance between the grinding wheel and the tool is inconsistent with a preset distance according to the signal fed back by the longitudinal distance measuring assembly.

A tool slide is added to the support table, and the clamping component can slide on the tool slide, so that the clamping component can not only drive the tool to move parallel to the support table, but also drive the tool to rotate parallel to the support table. In this way, the clamping component is changed from the original vertical design to a horizontal design; at the same time, a fixed support is also added to the support table, and the grinding component can be lifted and lowered on the fixed support, so that the grinding component can be lifted and lowered perpendicular to the support table.

The processing quality and processing efficiency of the tool chamfered edge are both improved. Description of the Drawings

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] In order to enable those skilled in the art in this technical field to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0046] An embodiment of the present invention discloses a tool edge processing device, as shown in the attached Figures 1 to 5 figure, which includes a support platform 1. A threaded pipe is fixedly installed at the center of the bottom of the support platform 1 for discharging cooling water during the grinding process. The top of the support platform 1 is a plane. Based on this plane, a clamping assembly 4 and a grinding assembly 5 are arranged on the support platform 1.

[0047] A tool slide 2 and a fixed support 3 are fixedly arranged on a support table 1. The support table 1 is rectangular. The tool slide 2 is arranged along the length direction of the support table 1, and the fixed support 3 is arranged along the width direction of the support table 1. An I-shaped support is fixedly arranged at the bottom of the tool slide 2, and the I-shaped support is fixed on the support table 1 by bolts, so that the tool slide 2 is fixed relative to the support table 1. The fixed support 3 is in an inverted T shape, and its bottom end is fixed on the support table 1 by bolts.

[0048] A clamping assembly 4 is slidably arranged on the tool slide 2 along a first direction. The clamping assembly 4 can drive the tool to rotate around a third direction. Both the first direction and the third direction are parallel to the support table 1, so that the clamping assembly 4 can drive the tool to move parallel to the support table 1 and also drive the tool to rotate parallel to the support table 1. In this way, the clamping assembly 4 is changed from the original vertical design to a horizontal design, which is convenient for the discharge of water flow during the grinding process and avoids large-area falling on the slide table.

[0049] A grinding assembly 5 is arranged on the fixed support 3 so as to be able to lift and lower along a second direction, so that the grinding assembly 5 lifts and lowers perpendicular to the support table 1. When the tool rotates one circle along with the clamping assembly 4, all the surfaces to be machined of the tool can be aligned with the grinding assembly 5 in turn. The grinding assembly 5 moves towards the opposite surfaces to be machined to grind chamfered edges on the surfaces to be machined.

[0050] By optimizing the structure of the tool edge processing equipment, the clamping assembly 4 is changed from a vertical design to a horizontal design, and the layout mode between the clamping assembly 4 and the grinding assembly 5 is changed. The clamping assembly 4 only needs to clamp the tool once, and the grinding assembly 5 can grind all the chamfered edges of the tool, so that all the chamfered edges of the tool are continuously machined, the problem of joint marks caused by discontinuous machining is eliminated, and a large amount of ineffective time occupied by frequent tool clamping is saved. The machining quality and machining efficiency of the chamfered edges of the tool are both improved.

[0051] It should be noted that Figure 4 Taking the coordinate system shown in the appendix as the standard, the first direction in the text refers to the direction of the X axis, the second direction refers to the direction of the Z axis, and the third direction refers to the direction of the Y axis.

[0052] As shown in the appendix Figure 4 and 5As shown in the figure, the clamping assembly 4 includes a clamping base 41, a clamping bracket 42, and a clamping turntable 43. The clamping base 41 is slidably disposed on the tool slide 2, enabling the clamping base 41 to slide relative to the tool slide 2 in the first direction. A sliding driving member 46 is mounted on the tool slide 2. The sliding driving member 46 is composed of a driving motor and a lead screw nut pair, but is not limited thereto. The tool slide 2 is provided with a first slide rail, and the clamping base 41 is provided with a first chute. The first slide rail and the first chute are slidably engaged to guide the linear sliding of the clamping base 41 along the tool slide 2. Limiting baffles 21 are integrally and vertically provided at both ends of the tool slide 2 to prevent the clamping base 41 from detaching from the tool slide 2.

[0053] The clamping bracket 42 is vertically fixed to the clamping base 41. The clamping turntable 43 is rotatably disposed on the clamping bracket 42, enabling the clamping turntable 43 to rotate relative to the clamping bracket 42 in the third direction. The clamping bracket 42 is fixedly connected to a support rotating shaft. The support rotating shaft is rotatably passed through the clamping bracket 42. A slewing bearing is provided between the support rotating shaft and the clamping bracket 42 to enable the relative rotation of the support rotating shaft and the clamping bracket 42. The support rotating shaft is connected to a rotating driving member 47 to drive the support rotating shaft to drive the clamping turntable 43 to rotate relative to the clamping bracket 42.

[0054] The clamping assembly 4 further includes a tool support 44 and an adjustment platform 45, which are connected between the clamping turntable 43 and the tool support 44 and are used to adjust the position of the tool support 44 in the first direction and the second direction, so as to finely adjust the tool in two directions of the X-axis and the Z-axis, ensure that the tool is accurately aligned with the grinding assembly 5, and improve the processing quality.

[0055] The adjustment platform 45 includes a vertical slide plate 451 slidably disposed on the clamping turntable 43 in the second direction and a horizontal slide plate 452 slidably engaged with the vertical slide plate 451 in the first direction. That is, the vertical slide plate 451 and the horizontal slide plate 452 are arranged in a cross shape. The vertical slide plate 451 is connected with a vertical driving member 453 for driving the vertical slide plate 451 to move relative to the clamping turntable 43 in the second direction. The horizontal slide plate 452 is connected with a horizontal driving member 454 for driving the horizontal slide plate 452 to move relative to the vertical slide plate 451 in the first direction. Both the vertical driving member 453 and the horizontal driving member 454 can adopt servo motors equipped with lead screw nut pairs, but are not limited thereto. For example, they can also be cylinders, etc.

[0056] The tool support 44 is vertically mounted on the adjustment platform 45 and can rotate synchronously with the clamping turntable 43 in the third direction, enabling the machined surface of the tool to be aligned with the grinding assembly 5. The tool support 44 is disc-shaped, and a number of clamping claws distributed in a circular ring shape are provided thereon. The clamping claws expand and contract radially, so that all the clamping claws clamp the tool by approaching each other.

[0057] As shown in the appendix Figure 4 and 5As shown, the grinding assembly 5 includes a grinding wheel 51, a grinding wheel driving member 52, and a swing turntable 53. The grinding wheel driving member 52 is connected to the grinding wheel 51 and is used to drive the grinding wheel 51 to rotate, so as to grind a chamfered edge on the tool. The grinding wheel driving member 52 includes a driving motor and a motor mounting seat for supporting the driving motor. The swing turntable 53 is fixedly connected to the grinding wheel driving member 52, specifically to the motor mounting seat, and is used to drive the grinding wheel 51 to swing around a third direction, so that the grinding wheel 51 swings up and down relative to the tool, adjust the distance between the grinding wheel 51 and the tool, thereby adjusting the size of the chamfered edge to meet different processing requirements, and having better adaptability. Specifically, the motor mounting seat is fixedly connected to the swing turntable 53 through a swing rotating shaft, and the swing rotating shaft is connected to a swing driving member, so that the swing driving member drives the motor mounting seat to swing around the third direction through the swing rotating shaft, enabling the grinding wheel 51 to swing up and down.

[0058] The grinding assembly 5 further includes a pitching turntable 54 and a grinding support 55. The pitching turntable 54 is fixedly connected to the swing turntable 53, so that the pitching turntable 54 drives the grinding wheel 51 to swing around a first direction through the swing turntable 53, so as to adjust the inclination angle of the grinding wheel 51, and further adjust the angle of the chamfered edge, machining chamfered edges of different specifications to meet different processing requirements, and having better adaptability. Specifically, the pitching turntable 54 is fixedly connected to the swing turntable 53 through a pitching rotating shaft. The pitching rotating shaft is perpendicular to the swing rotating shaft and is connected to a pitching driving member, so that the pitching driving member drives the pitching turntable 54 to rotate around the first direction through the pitching rotating shaft, thereby driving the swing turntable 53 to drive the grinding wheel 51 to swing around the first direction. One side of the grinding support 55 is rotatably connected to the pitching turntable 54, and the other side is slidably matched with the fixed support 3, so that the grinding support 55 can not only support the pitching turntable 54 to rotate, but also drive the grinding assembly 5 to lift along a second direction. The grinding support 55 is provided with a chute, and the fixed support 3 is provided with a slide rail. The slide rail is slidably matched with the chute and is used to guide the grinding support 55 to linearly lift along the fixed support 3. A lifting driving member is installed on the fixed support 3, and the lifting driving member is connected to the grinding support 55 and is used to drive the grinding support 55 to lift. The lifting driving member can specifically also be a servo motor configured with a lead screw nut pair, or a cylinder, etc.

[0059] A protective cover 56 is provided outside the grinding wheel 51, which can not only prevent the flying sand grains, debris and fragments generated by the splitting of the grinding wheel from scratching the operator, but also prevent the grinding fluid from splashing and affecting other moving components and detection components, ensuring that the whole set of equipment runs more reliably and the detection accuracy is higher. The protective cover 56 is provided with an avoidance hole to facilitate the detection of the grinding wheel 51.

[0060] The above-mentioned tool edge processing equipment further includes a passivation component 11. The passivation component 11 is slidably arranged on the support table 1 along the third direction and is opposite to the clamping component 4. After the grinding component 5 grinds a chamfered edge on the tool, the passivation component 11 passivates the chamfered edge of the tool clamped by the clamping component 4, and uses a brush to polish the ground chamfered edge to prevent the chamfered edge from chipping and improve the processing quality. The setting of the passivation component 11 realizes the concentration of grinding and passivation on a set of equipment. Facing two different processing technologies, the clamping step of the tool can be omitted, and continuous processing can be achieved with only one clamping, and both the processing quality and processing efficiency are relatively high. A motion slide 12 is installed between the passivation component 11 and the support table 1. The motion slide 12 is used to support the passivation component 11 to slide relative to the support table 1 along the third direction to approach or move away from the tool clamped by the clamping component 4. The motion slide 12 includes a fixed table plate fixedly connected to the support table 1 and a longitudinal slide plate fixedly connected to the passivation component. The fixed table plate and the longitudinal slide plate are slidably connected. The fixed table plate is equipped with a lead screw nut pair, and the slider of the lead screw nut pair is fixedly connected to the longitudinal slider, so that the servo motor drives the longitudinal slider to slide relative to the fixed table plate along the third direction through the lead screw nut pair. The structure and working principle of the passivation component 11 can refer to the prior art and will not be elaborated here.

[0061] The grinding component 5 further includes a pitching drive member connected to the pitching turntable 54 and used to drive the pitching turntable 54 to drive the grinding wheel 51 to swing around the first direction. The tool edge processing equipment further includes a longitudinal distance measuring component 6 and a control component. The longitudinal distance measuring component 6 is fixedly arranged on the support table 1 and is used to measure the longitudinal distance between the tool and the grinding wheel 51 along the third direction. The longitudinal distance measuring component 6 can specifically be a distance sensor, etc., but is not limited thereto.

[0062] The control component is respectively connected to the longitudinal distance measuring component 6 and the pitching drive member. When the longitudinal distance measuring component 6 detects that the longitudinal distance between the grinding wheel 51 and the tool is inconsistent with the preset distance, the longitudinal distance measuring component 6 feeds back a signal to the control component. After receiving the signal, the control component processes it and then sends a signal to the pitching drive member. The pitching drive member drives the pitching turntable 54 to drive the grinding wheel 51 to swing around the first direction, so that the grinding wheel 51 moves along the third direction to adjust the longitudinal distance between the grinding wheel 51 and the tool until it is consistent with the preset distance, realizing the automatic adjustment of the distance between the grinding wheel 51 and the tool, with high adjustment accuracy and being beneficial to improving the processing accuracy.

[0063] The cutting tool edge processing equipment further includes a path detection component 7, and the control component is respectively connected to the alarm and the path detection component 7. The path detection component 7 is fixedly arranged on the support table 1. Before the chamfering edge is ground by the grinding component 5, the path detection component 7 is used to measure the distances between the cutting tool and the grinding wheel 51 in the first direction and the second direction, and send the distance information in the two dimensions to the control component. The control component generates the actual movement path of the cutting tool, and then the control component compares whether the difference between the actual movement path and the preset movement path exceeds the preset range. If so, the control component controls the alarm to give an alarm, avoiding excessive movement deviation of the cutting tool during the processing and improving the processing accuracy. The path detection component 7 may specifically be a laser rangefinder, but is not limited thereto.

[0064] It should be noted here that the control component should include a signal receiving part, a signal judging part and a signal sending part. The signal receiving part is used to receive the electrical signals sent by detection components such as the longitudinal distance measuring component 6 or the path detection component 7. The signal judging part is electrically connected to the signal receiving part so that the signal judging part is used to judge whether the signal received by the signal receiving part is a trigger signal. The signal sending part is electrically connected to the signal judging part so that the signal sending part sends the judgment signal generated by the signal judging part to an execution part such as a pitching driving part or an alarm. The specific setting manners of the signal receiving part, the signal judging part and the signal sending part can refer to the prior art; in the present utility model, only the application scenarios of the above three are changed, and no substantial improvement is made to them. Obviously, the control component with this structure is widely applied to existing automatic control devices, such as MCU, DSP or single-chip microcomputer, etc. The key point of the present utility model is that the control component combines each detection component and each execution component in a one-to-one correspondence.

[0065] At least one detection support 8 is fixedly arranged on the support table 1. Calibration platforms 9 are arranged between the longitudinal distance measuring component 6 and the detection support 8 and between the path detection component 7 and the detection support 8. The calibration platform 9 is used to calibrate the positions of the longitudinal distance measuring component 6 or the path detection component 7, ensuring that the longitudinal distance measuring component 6 is aligned with the grinding wheel fifty-one, and the path detection component 7 is aligned with the cutting tool, making the detection result more accurate and the processing accuracy higher.

[0066] The calibration platform 9 includes a lifting table board 91 that can be lifted and lowered in the second direction, and a sliding table board 92 that is perpendicular to the lifting table board 91 and parallel to the support table 1 and can be slidably arranged on the detection support 8. Specifically, a vertical table board is provided on one side of the lifting table board 91, and the lifting table board 91 is slidably connected to the vertical table board, so that the lifting table board 91 can be lifted and lowered relative to the vertical table board in the second direction. A dovetail rail and a dovetail groove that cooperate with each other are provided between the lifting table board 91 and the vertical table board for guiding the sliding of the lifting table board 91 relative to the vertical table board. The vertical table board is fixedly connected to the sliding table board 92. The sliding table board 92 is parallel to the support table 1. A guiding table board is slidably provided at the bottom of the sliding table board 92. A rail and a groove that cooperate with each other are provided between the guiding table board and the sliding table board 92 for guiding the sliding of the sliding table board 92 relative to the guiding table board. The guiding table board is fixedly connected to the detection support 8. It should be added that locking screws are provided between the lifting table board 91 and the vertical table board and between the sliding table board 92 and the guiding slide board for locking the positions of the lifting table board 91 and the sliding table board 92, ensuring stable and reliable operation during the detection of the calibration platform 9, and more accurate detection results and higher detection accuracy.

[0067] The tool edge processing equipment further includes a waterproof baffle 10 disposed around the outer edge of the support table 1 and used to prevent the grinding fluid from splashing out. The bottom of the waterproof baffle 10 is provided with a folding edge that closely adheres to the support table 1 to ensure good sealing between the waterproof baffle 10 and the support table 1 and avoid leakage of the grinding fluid.

[0068] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0069] In this article, specific examples are used to elaborate on the principles and implementation modes of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
