Description

Technical Field

[0001] This invention relates to the field of machining, specifically to a multifunctional punching and scribing tool. Background Technology

[0002] In the current machining industry, punching and scribing are relatively common processes. In the past, when processing holes, cross lines were first drawn on the hole position, and then punching was used to make a dot at the intersection before drilling. However, with the increasing demands for quality in modern industrial manufacturing, and the fact that this method has a large error, it is gradually becoming unsuitable for punching and scribing holes on large plates and with various complex angles. Therefore, improving punching and scribing technology has become an indispensable task. Summary of the Invention

[0003] This invention provides a multifunctional tool for marking and drawing lines, which solves the above-mentioned problems and difficulties. This tool can accurately and quickly draw lines and mark points, and can also rotate at any angle to draw lines and mark points, including drawing circles.

[0004] Technical solution:

[0005] A multifunctional marking and scribing tool is provided, comprising: a marking mechanism, a rotary guide mechanism, and a positioning mechanism;

[0006] The punching mechanism is mounted on the rotary guide mechanism and can slide on the guide mechanism. The punching mechanism is used to punch downwards or to draw lines along the guide rail of the rotary guide mechanism. The punching mechanism can also rotate a certain angle on itself and read the value through the dial of the rotary guide mechanism. The positioning mechanism is used to limit the punching mechanism on the rotary guide mechanism.

[0007] Furthermore, the punching mechanism includes: a punch, a sleeve, a locating pin, a pull rod, a first pressure spring, a nut, and a handle;

[0008] The sleeve has a stepped through hole with the small end facing downwards. A punch is inserted into the small end, and a pull rod is inserted into the large end. The pull rod is a stepped cylindrical structure with the large section located on the stepped surface and fixedly connected to the punch. A pressure spring is sleeved on the small section and extends out of the stepped through hole. A nut serves as the upper end cap of the sleeve and is connected to the upper end face of the sleeve. A first pressure spring is pressed between the nut and the step. A handle is fixedly connected to the small section extending out of the stepped through hole.

[0009] The sleeve wall has a long hole in the radial direction, and a transverse groove is formed in the bottom and middle of the long hole in the radial direction to form a movement path groove for the positioning pin; a positioning pin is also connected to the side of the long section, and the positioning pin extends out from the movement path groove; the long hole in the movement path groove realizes the up and down movement of the positioning pin, and the transverse groove realizes the positioning and height direction limit.

[0010] Furthermore, the rotary guide mechanism includes: a positioning plate, a deep groove ball bearing, a guide plate, balls, an angle bracket, and a cam ring;

[0011] Two positioning plates connect to two guide plates; the two guide plates form a guide rail, and the guide rail has a V-groove on its side for guiding. The angle frame is divided into a sliding section and a dial. A V-groove is provided on the outer end face of the sliding section. The two V-grooves are opposite to each other to form a diamond-shaped cavity for accommodating the ball. A stepped hole with a deep groove ball bearing is provided inside the angle frame. The small hole of the stepped hole faces downward. The small end and the lower part of the large end are inserted into the stepped hole. A pointer is radially provided on the outer edge of the sleeve, and the lower end face of the pointer is attached to the dial.

[0012] Furthermore, the punching mechanism also includes: a rolling nut and a ejector pin;

[0013] A rolling nut is connected to the lower side of the sleeve via a ejector pin. Rotating the rolling nut can cause the ejector pin to press against the angle plate of the rotary guide mechanism or to loosen it.

[0014] Furthermore, baffles are installed at both ends of the diamond-shaped cavity to prevent the balls from slipping out.

[0015] Furthermore, a convex ring made of transparent glass with magnifying function is covered around the scale of the dial.

[0016] Furthermore, the positioning mechanism includes a cam carrier, a spring, and a push rod;

[0017] The cam holder is installed on the sliding section of the cam holder. The cam at the top of the cam holder pushes against the push rod fitted with a spring. The push rod is set along the width of the track and points to the V-groove on the side of the track. The cam has an eccentric structure. When the cam does not rotate, the push rod retracts. When the cam rotates, it pushes the push rod out to the V-groove.

[0018] Furthermore, the second cylindrical pin connects the cam holder to a groove on one side of the angle holder.

[0019] Beneficial effects:

[0020] 1. This tool integrates a compass, ruler, drawing needle, angle gauge, and punch, and can perform multiple functions during use.

[0021] 2. This tool can quickly and accurately complete the processing, avoiding the need to switch tools and improving processing efficiency.

[0022] 3. The device is inexpensive to manufacture and suitable for large, medium and small enterprises. Attached Figure Description

[0031] To make the solutions and advantages of the present invention clear and specific, the following description, in conjunction with the accompanying drawings, provides a complete and clear account of the various parts of the apparatus and the overall embodiments of the present invention.

[0032] It should be noted that the term "positioning" mentioned in this embodiment can refer to a sliding fit between parts or a tight contact between parts; "connection" refers to a rivet connection, a cylindrical pin connection or a threaded connection, and engineers can understand it according to the actual connection situation.

[0033] Combination Figure 1-8 The multifunctional marking and scribing tool includes: a marking mechanism, a rotary guide mechanism, and a positioning mechanism.

[0034] The punching mechanism includes: punch 2, sleeve 8, pull rod 10, pressure spring 11, nut 12, first cylindrical pin 13, handle 14, baffle 16, rolling nut 20, and ejector pin 21.

[0035] The rotary guide mechanism includes: positioning plate 1, deep groove ball bearing 3, ball bearing 4, guide plate 5, ball bearing 6, angle bracket 7, rivet 22, and convex ring 23.

[0036] The positioning mechanism includes: cam frame 15, second cylindrical pin 17, spring 18, and push rod 19.

[0037] In the punching mechanism, the punch 2 and the pull rod 10 are respectively positioned in the sleeve 8, and the punch 2 and the pull rod 10 are tightly connected. A positioning pin 9 is also connected to the lower side of the pull rod 10. The positioning pin 9 is positioned in the groove of the sleeve 8. A pressure spring 11 is installed on the pull rod 10. The pressure spring 11 is pressed by the nut 12 connected to the sleeve 8. A handle 14 is connected to the pull rod 10 through the first cylindrical pin 13. A rolling nut 20 is connected to the lower side of the sleeve 8 through the ejector pin 21. Rotating the rolling nut 20 can cause the ejector pin 21 to press against the angle plate 7 or to loosen it.

[0038] The rotary guide mechanism, as shown Figure 1 As shown, Figure 1 The two positioning plates 1 at the left and right ends, and the two guide plates 5 connected to the two positioning plates 1 by four rivets 22, are as follows: Figure 3 The guide plate 5 is positioned on the left and right sides by the positioning plate 1. Simultaneously, four ball bearings 4 are positioned at the lower ends of the positioning plates 1 to reduce friction between the tool and the workpiece during use. Figure 3 Three ball bearings 6 are positioned in the guide plates 5 on both sides by forming two V-shapes with the angle bracket 7 to reduce the friction of the angle bracket 7 sliding on the guide plates 5.

[0039] Next, a deep groove ball bearing 3 is installed in the center of the angle frame 7 to facilitate the rotation of the sleeve 8 in the angle frame 7. An angle is engraved on the upper surface of the angle frame 7. At the same time, a transparent glass convex ring 23 with magnification function is connected to the upper surface of the angle frame 7 to facilitate the positioning of the angle when the sleeve 8 is rotated to a certain angle.

[0040] The positioning mechanism includes Figure 2 In the middle, the second cylindrical pin 17 connects the cam frame 15 to the groove on one side of the angle frame 7, and pushes against the push rod 19 pressing on the pressure spring 18.

[0041] The specific implementation method listed here is only one type of method: drawing a cross center line and evenly distributing 6 punches around the intersection of the cross on a diameter of φ100mm. Other methods of drawing lines and punching points can be flexibly applied according to the actual situation.

[0042] First, use the multi-functional punching and scribing tool to find and mark the two center lines of the workpiece. Then, place the multi-functional punching and scribing tool on the workpiece and align the scale lines on the positioning plates 1 at both ends with the marked lines. Next, move the cam frame 15 of one positioning mechanism outward to release the positioning push rod 19. Then, push the punching mechanism along the guide plate 5 of the rotary guide mechanism towards one end of the tool. Then, rotate the handle 14 to make the positioning pin 9, which was initially located in the horizontal groove above the sleeve 8, fall down along the long groove on the sleeve 8. At this time, press the handle 14 with your palm and drag the punching mechanism along the guide plate 5 of the rotary guide mechanism towards the other end of the tool. This completes one scribing. The scribing method in the other direction is the same.

[0043] After marking all the crosshairs, align the 0 mark on the positioning plates 1 at both ends of the tool with any of the marked lines. Then, pull the handle 14 upwards and rotate it so that the positioning pin 9 is in the horizontal groove above the sleeve 8. Next, drag the punching mechanism so that the pointer at the lower end of the sleeve 8 is aligned with another marked line. Then, the cam frame 15 is pushed inwards so that the push rod 19 presses against the inner side of the guide plate 5 in a V-shape to fix the rotating guide part. Then, rotate the handle 14 to put the positioning pin 9, which was initially in the horizontal groove above the sleeve 8, into the long groove and pull it upwards to the maximum stroke. Release the handle 14, and as the positioning pin 9 falls, the crosshairs are punched on the workpiece.

[0044] Next, following the above method, move the cam holder 15 of the other rotary guide mechanism outward to release the positioned push rod 19. Then, using the coordinates on the tool at the just-punched point as the center, drag the punching mechanism along the guide plate 5 of the rotary guide mechanism by half of the φ100mm diameter. Then, move the cam holder 15 inward to make the push rod 19 press against the inner side of the guide plate 5 in a V-shape to position the rotating guide part. Next, hold the punching mechanism at the just-punched point with your hand, and drag the other punching mechanism around it as the center point. Observe the angle scale on the punching mechanism at the just-punched point. When it has just rotated to 60°, move the rolling nut 20 of the punching mechanism at the just-punched point to make the push pin 21 press against the punch. The upper end of the punching mechanism positions the rotating part of the rotary guide mechanism. Then, the handle 14 of another punching mechanism is rotated to place the positioning pin 9, which is initially in the horizontal groove above the sleeve 8, into the long groove and pull it upward to the maximum stroke. When the handle 14 is released, the positioning pin 9 falls down, and one of the 6 points evenly distributed on the φ100mm diameter is punched on the workpiece. Then, the rolling nut 20 of the punching mechanism that just punched the point is turned so that the ejector pin 21 is released and the upper end of the punching mechanism positions the rotating part of the rotary guide mechanism. Then, the handle 14 of another punching mechanism is pulled so that the positioning pin 9 is in the horizontal groove above the sleeve 8. Then, the other points are punched in the same way to complete the punching of 6 points evenly distributed on the φ100mm diameter.
