Description

Technical Field

[0001] The invention relates to the technical field of crystal cutting and processing, in particular to a cylindrical crystal processing tool. Background Art

[0002] At present, when processing crystal into a cylindrical shape, it is necessary to use a machine tool to drive the cylindrical tool to descend to cut the crystal. In order to ensure the cutting effect, the cutting fluid and cutting residue inside the tool must be discharged in time, and the cutting fluid must be able to flow all the way to the cutting point. After advancing a certain distance, the tool must be retracted and then re-entered. Currently, the operation of retracting and re-entering is mostly done manually. When the staff is not skilled, it is easy for them to not master the timing of retracting the tool, which affects the cutting effect. In addition, the blade of the tool will wear out after long-term use. If the worn tool is continued to be used at this time, it is easy to reduce the cutting effect. In order to solve the above problems, the present invention provides a cylindrical crystal processing tool. Summary of the Invention

[0003] In response to the above-mentioned technical deficiencies, the purpose of the present invention is to provide a cylindrical crystal processing tool that can automatically retract after feeding a certain distance, making it convenient for staff to operate. When the blade of the tool body is worn, the number of rotations of the tool body during the feeding process does not match the feeding distance. At this time, the tool body will idle and rise, which can promptly remind staff to replace the tool body with worn blade or grind the blade of the tool body.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a cylindrical crystal processing tool, comprising: a tool body, the tool body is cylindrical with an open lower end, a cutting edge is provided at the lower opening of the tool body, and a plurality of through holes are opened on the closed end of the tool body, and further comprising: A fixing rod, the fixing rod is fixedly connected to the closed end of the cutter body, and the axis of the fixing rod and the axis of the cutter body are on the same vertical line, and the outer side surface of the fixing rod is provided with an external thread; There are two arc plates, and the two arc plates are symmetrical to each other through the axis of the fixed rod. The inner side of the arc plate is provided with an internal thread that matches the external thread of the fixed rod. Adjusting the spacing between the two arc plates can control the engagement and disengagement of the fixed rod, and then control the lifting and lowering of the fixed rod. The spacing between the two arc plates changes with the height of the fixed rod.

[0005] The transmission shaft is located above the fixed rod and is connected to the drive shaft of the external machine tool. It can drive the fixed rod to rotate, and the height of the fixed rod changes accordingly when it rotates; The mounting frame is installed on the arc plate, and the mounting frame is installed on the supporting arm of the external machine tool driving shaft.

[0006] Preferably, an elastic member is connected between the fixing rod and the transmission shaft, and the elastic member has an elastic tendency to pull the fixing rod upward.

[0007] Preferably, the two arc plates are connected to each other via a plurality of connecting components; A push rod is symmetrically installed on the upper end of the fixed rod. When the fixed rod is lowered to a specified height, the push rod presses against the connecting assembly on the lower side, causing the two arc plates to move away from each other and disengage from the fixed rod. When the fixed rod is raised to a specified height, the push rod presses against the connecting assembly on the upper side, causing the two arc plates to move toward each other and engage with the fixed rod.

[0008] Preferably, the connection assembly comprises: There are two connecting rods, the proximal ends of the two connecting rods are hinged to each other, and the distal ends are hinged to the corresponding arc plates. The angle between the upper side surfaces of the two connecting rods is a reflex angle, and the projection of the top rod coincides with the projection of the corresponding hinge point where the two connecting rods are hinged to each other.

[0009] Preferably, the push rod is fixedly connected to the swivel, and the swivel is rotatably connected to the outer side of the upper end of the fixed rod.

[0010] Preferably, a limit rod is provided on the outer side of multiple connecting rods on the same side, and the hinge points at the proximal ends of the two connecting rods at the same height are rotatably connected to the limit rod, and the outer end of the top rod extends into the limit groove opened on the limit rod and is slidably connected to the limit groove.

[0011] Preferably, the lower end of the transmission shaft is fixedly connected to a rod body; The lower end of the rod body extends to the inside of the empty slot on the fixed rod, and the transmission shaft can drive the fixed rod to rotate through the rod body when rotating, and the fixed rod can slide along the track of the rod body.

[0012] Preferably, the mounting frame comprises: Two mutually symmetrical base plates, the two base plates are symmetrical to each other through the axis of the fixed rod, and the upper ends of the base plates are connected to the support frame of the machine tool drive shaft; Multiple support rods, one end of the support rod is fixedly connected to the corresponding arc plate, the other end passes through the corresponding base plate and folds around to form a circular plate, and damping is provided between the support rod and the base plate.

[0013] Preferably, a recessed groove is provided at the closed end of the blade body, and the upper end opening of the through hole is higher than the bottom side wall of the recessed groove. A plurality of through grooves are fixedly connected to the groove wall of the recessed groove, and the lower end of the through groove extends to the blade portion at the lower end of the blade body.

[0014] The beneficial effects of the present invention are: The present invention realizes that the fixed rod descends during the rotation process to achieve the knife feed through the arrangement of the arc plate and the fixed rod, and when it descends to a specified height, the top rod presses against the connecting component on the lower side, at which time the arc plate is disengaged from the fixed rod, and under the action of the elastic member, the fixed rod drives the knife body to rise to achieve the knife retraction, and when it rises to the specified height, the top rod presses against the connecting component on the upper side, at which time the arc plate is engaged and connected with the fixed rod, and the fixed rod continues to descend, thereby achieving automatic knife retraction and facilitating the operation of the staff.

[0015] When the blade of the knife body of the present invention is worn, the number of rotations of the knife body and the feed distance will not match. At this time, the fixed rod will squeeze the two arc plates apart and no longer engage with the arc plates, so that the fixed rod will drive the knife body to rise, reminding the staff that the blade of the knife body is worn, thereby avoiding the reduction of cutting effect due to blade wear.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1: like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the present invention provides a cylindrical crystal processing tool, including a cylindrical tool body 1 with an opening at the lower end, and a plurality of through holes are provided on the upper end surface of the tool body 1, so that the tool body 1 can feed smoothly during cutting, and a fixing rod 3 is fixedly connected to the tool body 1, and the outer side surface of the fixing rod 3 is provided with an external thread, which can be engaged with two symmetrical arc plates 4, and the inner side surface of the arc plate 4 is provided with a corresponding internal thread, and the upper end of the fixing rod 3 is connected to a transmission shaft 5, and the transmission shaft 5 is interconnected with the drive shaft of an external machine tool, and the transmission shaft 5 will drive the fixing rod 3 to rotate clockwise, and the clockwise rotation of the fixing rod 3 can move downward to realize feeding, and an elastic member 14 is also connected between the transmission shaft 5 and the fixing rod 3, and the elastic member 14 has an elastic tendency to pull the fixing rod 3 upward, and the elastic member 14 can be a spring.

[0027] A connecting rod 8 is hinged on one side of the two arc plates 4 that are close to each other, and the corresponding ends of the two connecting rods 8 that are close to each other are hinged to each other, and the angle between the upper side surfaces of the corresponding two connecting rods 8 is an advantageous angle (the advantageous angle is an angle less than 360 degrees and greater than 180 degrees). The two arc plates 4 are respectively connected to the mounting brackets 6, and the spacing between the two arc plates 4 can be adjusted.

[0028] The upper end of the fixed rod 3 is symmetrically connected to the push rod 7 through the swivel 9. When the fixed rod 3 descends, it can drive the push rod 7 to descend synchronously. When the push rod 7 descends to a specified height, it can press against the two connecting rods 8 below it. At this time, the angle between the upper side surfaces of the two connecting rods 8 that are pressed together will be reduced, and the two arc plates 4 will move away from each other. The arc plate 4 will disengage from the fixed rod 3. At this time, under the action of the elastic member 14, the fixed rod 3 and the knife body 1 will move upward to achieve knife retraction.

[0029] When the fixed rod 3 rises, it will drive the top rod 7 to rise synchronously. When the top rod 7 rises to the specified height, it can press against the two connecting rods 8 above it. At this time, the angle between the upper side surfaces of the two connecting rods 8 that are pressed together will increase, and the two arc plates 4 will approach each other. The arc plates 4 will engage with the fixed rod 3. At this time, the fixed rod 3 will continue to descend if it rotates clockwise to achieve feed.

[0030] During the above process, the staff only needs to continuously operate the driving shaft of the machine tool to descend, which makes it convenient for the staff to operate.

[0031] The lower end of the transmission shaft 5 is fixedly connected to a rod body 10, which extends into a hollow groove 11 provided on the fixed rod 3 and is slidably connected to the hollow groove 11. When the transmission shaft 5 rotates, it can drive the fixed rod 3 to rotate synchronously through the rod body 10, and at the same time, the fixed rod 3 can slide up and down smoothly along the rod body 10.

[0032] The mounting frame 6 includes a plurality of support rods 602 fixedly connected to the arc plate 4 and a base plate 601 on the support frame for mounting the drive shaft of the shaft machine tool. The outer ends of the support rods 602 pass through the base plate 601 and are slidably connected to the base plate 601 (the end of the support rod 602 away from the arc plate 4 is the outer end), so that the arc plate 4 can slide in the horizontal direction. The outer ends of the support rods 602 are folded to the four sides to form a circular plate. The diameter of the circular plate is larger than the diameter of the support rods 602, which can prevent the support rods 602 from slipping off the base plate 601.

[0033] The arc plate 4 is installed on the mounting frame 6, and the mounting frame 6 is installed on the support frame of the machine tool drive shaft. When the staff operates the drive shaft to descend, the support frame will also descend synchronously. At the same time, the support frame will not rotate with the drive shaft, that is, the arc plate 4 and the fixed rod 3 rotate relative to each other.

[0034] Example 2: like Figure 3 As shown, based on the first embodiment, in order to improve the cutting stability and avoid the wear of the blade 1 causing a decrease in cutting effect, a damping is set between the support rod 602 and the base plate 601, specifically as follows: A damper is provided between the support rod 602 and the base plate 601, so that when the resistance encountered by the blade body 1 during the descent is not greater than the friction force of the damper, the blade body 1 can be smoothly lowered to perform cutting work. Moreover, after the arc plates 4 move away from or approach each other, when the external force encountered is not greater than the friction force between the dampers, the arc plates 4 will not slide at will, thereby ensuring the stability of the cutting.

[0035] When the number of revolutions of the blade body 1 does not match the distance of descent, it means that the blade of the blade body 1 is damaged (for example, the blade body 1 will drop 5mm for every 10 revolutions. When the blade of the blade body 1 is damaged, the cutting effect of the blade body 1 is reduced. At this time, the distance of descent of the blade body 1 will be less than 5mm for every 10 revolutions of the blade body 1). The fixed rod 3 will move synchronously with the blade body 1. When the number of revolutions of the fixed rod 3 does not match the distance of descent, the external thread on the fixed rod 3 will push the arc plate 4 open, so that the arc plate 4 can overcome the friction force of the damping and move away from each other. The arc plate 4 will disengage from the fixed rod 3, so that the elastic member 14 can lift the fixed rod 3 and the blade body 1, thereby preventing the blade body 1 with damaged blade from continuing to cut and affecting the cutting effect.

[0036] Example 3: like Figure 6 As shown, based on the second embodiment, in order to improve the cooling effect of the cutting fluid on the cutting edge of the cutter body 1, a through groove 13 is provided, specifically as follows: A sink 12 is provided at the closed end of the cutter body 1, and the upper end opening of the through hole 2 is higher than the bottom side wall of the sink 12. At this time, cutting fluid can be added to the inside of the sink 12. A plurality of through grooves 13 are provided on the groove wall of the sink 12. The lower end of the through groove 13 extends to the cutting edge of the cutter body 1. The cutting fluid inside the sink 12 can flow directly to the cutting edge of the cutter body 1 through the through grooves 13, thereby better cooling the cutting edge of the cutter body 1.

[0037] Example 4: like Figure 7 As shown, based on the first embodiment, in order to ensure that the projection of the top rod 7 coincides with the projection of the hinge point where the two corresponding connecting rods 8 are hinged to each other, a limiting rod 15 is provided. Specifically, it is as follows: A limit rod 15 is provided on the outer side of the multiple connecting rods 8 on the same side that are hinged to each other, and the connecting rods 8 are rotatably connected to the limit rod 15. A limit groove is provided on the limit rod 15, and the outer end of the top rod 7 extends to the inside of the limit groove. The setting of the limit rod 15 can prevent the top rod 7 from rotating with the rotation of the fixed rod 3, ensuring that the projection of the top rod 7 coincides with the projection of the hinge point where the corresponding two connecting rods 8 are hinged to each other, so that the top rod 7 can change the angle of the corresponding two connecting rods 8 when it is pressed against the corresponding connecting rod 8, and then stably adjust the distance between the two arc plates 4.

[0038] At the same time, the limiting rod 15 can connect multiple connecting rods 8 on the same side to each other, so that when the top rod 7 changes the angle of the connecting rod 8 in contact with it, the angles of all connecting rods 8 on the same side can be changed at the same time, thereby further stabilizing the adjustment of the distance between the two arc plates 4.

[0039] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
