Description

Technical Field

[0001] The utility model relates to a height tool setting instrument. Background Art

[0002] With the rapid development of industries such as automobiles, ships, and aerospace, parts processing is also developing towards personalization and complexity. Before processing, parts need to locate their reference origin. The accuracy of this positioning is directly related to the form and position tolerances of the part size and shape, affecting the processing yield. This requires a tool setter that can locate the reference. Existing height tool setters on the market have the following shortcomings during use:

[0003] 1. Traditional tool setters use a vertical mode for tool setting, that is, the spindle tool contacts the tool setter from top to bottom for tool setting. When changing parts during machine tool processing, cutting fluid is often left on the tool and the machine spindle. At this time, when setting the parts at a high level, it is inevitable that the coolant on the spindle tool will drip into the gap at the edge of the contact. The cutting fluid enters the tool setter and forms metal impurities that remain in the gap, affecting the normal use of the tool setter. In severe cases, it may even damage the internal components.

[0004] 2. Most tool setters on the market currently require the tool to move down along the axis of the tool setter during the tool setting operation. During use, the tool is often moved carefully and slowly to avoid the situation where the tool is moved quickly and instantly contacts the tool setter, which may damage the tool setter and result in low operating efficiency. Summary of the Invention

[0005] The technical problem to be solved by the utility model is: to provide a height tool setting instrument, which uses one end of a tool setting plate to contact the tool for tool setting, and the surface of the tool setting plate in contact with the tool is concave. On the one hand, it can prevent the coolant on the tool from flowing into the interior of the tool setting instrument and causing damage to the components. On the other hand, using the surface of the tool setting plate to set the tool makes observation more intuitive and the tool setting operation safer and more convenient.

[0006] The technical solution to solve the above technical problems is: a height tool setting instrument, including a tool setting plate, a spring, an adjusting nut, a circular sleeve, a conductive contact, a light-emitting body, a resistor, a battery, an end cover, a metal body and a metal base, one end of the tool setting plate is set to a step shape with the end lower than the middle part, and a counterweight block is installed at the other end of the tool setting plate, the lower end of the tool setting plate is connected to the circular sleeve, and a guide groove is provided at the lower end of the circular sleeve, the upper end of the metal body is located in the circular sleeve, and a guide key is fixed at the upper end of the metal body, and the guide key is located in the guide groove of the circular sleeve, and a vertical mounting hole is provided in the metal body, and the adjusting nut passes through the tool setting plate and extends into the vertical mounting hole of the metal body, and the adjusting nut is connected to the tool setting plate by a thread, and the vertical mounting holes are spring mounting holes, contact mounting holes, threading holes, component mounting holes and battery mounting holes from top to bottom, and the spring mounting holes, contact mounting holes and threading holes are arranged in the order of the vertical mounting holes. The diameters become smaller in sequence, and the spring is sleeved on the outside of the adjusting nut. The upper end of the spring contacts the knife plate, and the lower end of the spring is connected to the bottom surface of the spring mounting hole. The conductive contact is located directly below the adjusting nut and placed in the contact mounting hole. An insulating circular ring is interference-installed on the outside of the conductive contact, and a spring 2 is arranged between the insulating circular ring and the bottom end of the contact mounting hole. The light-emitting body and the resistor are located in the component mounting hole, and the battery is located in the battery mounting hole. An insulating sleeve is sleeved on the outside of the battery, and the bottom end of the battery is fixed by a metal end cover. The metal end cover is located in the insulating sleeve and is threadedly connected to the insulating sleeve. The conductive contact is connected to the light-emitting body, the resistor, and the battery through a wire. A horizontal light-transmitting hole connected to the component mounting hole is also provided on the metal body, and the bottom end of the metal body is mounted on the metal base; when there is no external force, there is a distance between the adjusting nut and the conductive contact, and when the adjusting nut contacts the conductive contact, the light-emitting body lights up.

[0007] Furthermore, the tool setting plate is composed of end circular plate one, end circular plate two and a middle square plate connecting the two end circular plates. The height of end circular plate one is smaller than that of the middle square plate, that is, end circular plate one and the middle square plate form a step shape, and the height of end circular plate two is the same as that of the middle square plate. The counterweight block is a cylinder, and the counterweight block is installed on end circular plate two. The adjusting nut passes through the middle of the middle square plate.

[0008] Furthermore, the metal body and the metal base are both cylindrical, and the metal body is eccentrically mounted on the metal base.

[0009] Furthermore, a lens is installed at the end of the transverse light-transmitting hole.

[0010] Furthermore, a slot is formed on the top of the adjusting nut.

[0011] Furthermore, a standard tool setting block is also provided, and the standard tool setting block is a concave block with an inner standard groove.

[0012] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0013] 1. The tool is set with one end of the tool setting plate in contact with the tool. The end face of the tool setting plate in contact with the tool has a concave step surface. Even if coolant flows out of the tool, it will remain on the concave step surface, which is easy to clean. The liquid will not flow into the gap between the tool setting plate and the adjusting nut threaded connection, thus avoiding the coolant entering the tool setting instrument and damaging the internal components, which can effectively ensure the normal use of the tool setting instrument.

[0014] 2. One end of the tool setting plate is in contact with the tool for tool setting. When observing the placement position and the entire tool setting process, the viewing angle is wider and it is easier to capture the tool setting point (the moment when the tool drives the tool setting plate to move downward to the light source); in addition, the area where the tool setting plate can contact the tool is larger, and the spring provided under the conductive contact has a buffering effect, which can avoid hard collision of the conductive contact. Therefore, the tool can move normally without slow and cautious movement, which can improve the efficiency of tool setting.

[0015] 3. The tool setting plate adopts a lever-like design, and a counterweight is designed at the other end of the tool setting plate to ensure the balance of the tool setting.

[0016] The technical features of the height tool setting instrument of the present invention will be further described below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the tool setting plate 1 (the tool setting part) is set to a step shape with the end lower than the middle part, that is, the end of the tool setting plate used for tool setting is designed as a concave step, and the other end of the tool setting plate is installed with a counterweight block 7. The lower end of the tool setting plate 1 is connected to the circular sleeve 5 by a fixing screw 2, and guide grooves 51 are symmetrically provided on both sides of the lower end of the circular sleeve 5. The upper end of the metal body 17 is located in the circular sleeve 5, and two grooves are symmetrically provided on both sides of the upper end of the metal body 17. A guide key 6 is fixed in the groove, and the guide key 6 is located in the guide groove 51 of the circular sleeve 5. The guide key 6 is clearance-matched with the guide groove 51. The guide key 6 can move up and down in the guide groove 51, and the guide key 6 plays a role in limiting circumferential rotation. The metal body 17 is provided with a vertical mounting hole. The adjusting nut 4 passes through the blade setting plate 1 and extends into the vertical mounting hole of the metal body 17. The adjusting nut 4 is connected to the blade setting plate 1 by a thread. The adjusting nut 4 can be rotated to adjust its relative position with the blade setting plate 1, thereby adjusting the height of the blade setting plate 1. The vertical mounting holes are, from top to bottom, a spring mounting hole 171, a contact mounting hole 172, a threading hole 173, a component mounting hole 174, and a battery mounting hole. The diameters of the spring mounting hole 171, the contact mounting hole 172, and the threading hole 173 decrease in size. The spring 13 is sleeved on the outside of the adjusting nut 4. The upper end of the spring 13 contacts the blade setting plate, and the lower end of the spring is connected to the bottom surface of the spring mounting hole 171. When the blade setting plate 1 is pressed downward, the spring 13 rebounds and returns to its original position. The conductive contact 8 is located directly below the adjusting nut 4 and is placed in the contact mounting hole 172. An insulating circular ring 9 is installed on the outside of the conductive contact 8 with interference fit. The insulating circular ring 9 contacts the inner wall of the contact mounting hole 172 but is not connected. A spring 2 10 is provided between the insulating circular ring 9 and the bottom end of the contact mounting hole. The lower end of the insulating circular ring 9 is fixed to the upper end of the spring 2 10, and the lower end of the spring 2 10 is fixed to the bottom end of the contact mounting hole 172. The spring 2 10 plays a buffering role to prevent the conductive contact 8 from a hard collision. The light-emitting body 12 and the resistor 13 are located in the component mounting hole, the battery 15 is located in the battery mounting hole, an insulating sleeve 14 is mounted on the outside of the battery, the bottom end of the battery is fixed by a metal end cover 16, the metal end cover is located in the insulating sleeve 14 and is threadedly connected to the insulating sleeve, the conductive contact 8 is connected to the light-emitting body 12, the resistor 13, and the battery 15 through a wire, that is, the conductive contact 8 is connected to the negative pole of the light-emitting body 12 through a wire (the wire passes through the threading hole 173), the positive pole of the light-emitting body 12 is connected to one end of the resistor 13, and the other end of the resistor 13 is connected to the positive pole of the battery 15.The metal body 17 also has a transverse light-transmitting hole 175 that communicates with the component mounting hole. The bottom end of the metal body 17 is mounted on a metal base 19. The lower end of the metal body 17 contacts the top surface of the metal base 19 and is secured with bolts 18. A sealing ring is placed in the countersunk groove of the bolt at the lower end of the metal base 19 to prevent the ingress of oil and other contaminants. The concave step surface at one end of the tool setting plate 1 of the installed height tool setting instrument is parallel to the bottom surface of the metal base 19. When there is no external force, there is a gap between the adjustment nut 4 and the conductive contact 8, and they do not touch. When the adjustment nut and the conductive contact contact contact contact, the light source 12 illuminates.

[0029] In this embodiment, the tool setting plate 1 is composed of a first end circular plate 101, a second end circular plate 102, and a middle square plate 103 connecting the two end circular plates. The first end circular plate 101 is shorter than the middle square plate 103, i.e., the first end circular plate and the middle square plate form a step-like shape, while the second end circular plate 102 is the same height as the middle square plate. The counterweight 7 is cylindrical and mounted on the second end circular plate 102. The adjusting nut 4 passes through the middle of the middle square plate 103. As an alternative, the shape of the tool setting plate 1 can also be adjusted according to actual needs.

[0030] In this embodiment, the metal body 17 and the metal base 19 are both cylindrical, and the metal body is eccentrically mounted on the metal base. A lens 11 is mounted at the end of the transverse light-transmitting hole. A slot 41 is formed at the top of the adjusting nut 4.

[0031] In this embodiment, a standard tool setting block 21 is also provided. The standard tool setting block is a concave block with an inner standard groove, such as Figure 5-Figure 6 As shown in the figure, the height D of the internal standard groove corresponds to the tool setting height of the height tool setter. In this embodiment, the height tool setter is designed for a tool setting height of 50mm. Therefore, the height D of the internal standard groove of the standard tool setter block is designed to have a tolerance range of 50±0.003mm. As an alternative, a micrometer with a fixed height of 50mm can be used instead. The measurement height of the height tool setter is designed based on the size of the part and the contact area of ​​the reference surface. If the contact area of ​​the part is small, the height of the entire height tool setter and the diameter of the metal base can be appropriately reduced to accommodate different measurement ranges.

[0032] Before using the height tool setting instrument, it must be calibrated with a standard tool setting block, such as Figure 7As shown, the concave step surface on the left side of the tool setting plate 1 of the height tool setting instrument is placed close to the top surface of the inner standard groove of the standard tool setting block, and the bottom surface of the metal base 19 is placed on the bottom surface of the inner standard groove of the standard tool setting block. The nut 4 is adjusted by the knob to move it downward. When the bottom surface of the contact adjustment nut 4 contacts the conductive contact 8, the negative pole of the battery 15 is conductively connected to the negative pole of the light-emitting body 12 through the metal body of the height tool setting instrument to form a circuit (the current is connected to the negative pole of the light-emitting body 12 through the wire through the conductive contact 8. Since the positive pole of the light-emitting body 12 is connected to the resistor 13 through the wire and then to the positive pole of the battery 15, the negative pole of the battery 15 is connected to the metal base 19, the metal body 17, the spring 13, the tool setting plate 1, the adjusting nut 4 and the conductive contact 8 to form a working circuit). At this time, the light-emitting body 12 is lit, and the light is emitted through the side hole and the lens 11. At this time, the calibration of the height tool setting instrument is completed.

[0033] Height tool setting instrument tool setting operation Figure 8-Figure 9 As shown, install the height tool setter on the reference surface of the part to be measured, move the XY coordinates of the tool on the CNC machine tool spindle (the machine tool spindle rotation stops at this time), and stop moving when the bottom surface of the tool is above the stepped surface of the concave part on the left side of the tool setting plate 1; adjust the Z axis feed rate of the CNC machine tool and move it downward slowly. When the tool contacts the concave stepped surface on the left side of the tool setting plate 1, adjust the Z axis feed rate to the X100 gear, that is, it moves 0.001mm per rotation. The tool will generate pressure on the tool setting plate 1 during the downward pressing process. In order to ensure that the entire tool setting plate 1 moves downward horizontally, a counterweight block 7 is designed on the right side of the tool setting plate 1 to ensure the balance of the tool setting (that is, the pressure of the tool pressing down on the stepped surface of the concave part on the left side of the tool setting plate 1 + the gravity of the counterweight block 7 on the right side of the tool setting plate 1 = the spring force of spring 3). The tool drives the tool setting plate 1 to move downward until the adjusting nut 4 contacts the conductive contact 8 for a moment. At this time, the light source 12 lights up and light is seen from the lens 11. At this time, the tool is stopped. The current coordinate is exactly 50mm away from the part reference surface. Note the current mechanical coordinate of the Z axis of the CNC machine tool and subtract 50mm from the tool setting instrument height. The obtained coordinate is the Z axis part origin coordinate in the CNC machine tool G54.
