Description

Technical Field

[0001] The utility model relates to the technical field of guide rail processing and drilling equipment, and specifically relates to a hole position positioning device for guide rail processing. Background Technique

[0002] Drilling holes in the lead screw guide rail is a commonly used method in machining. One important reason is to reduce the weight of the guide rail and improve the load capacity of the equipment. At the same time, drilling holes in the guide rail also has the advantages of improving the rigidity of the equipment and facilitating the installation and upgrade of the equipment.

[0003] In the prior art, a drilling device is usually used to drill holes in the guide rail. For example, a "drilling device with a positioning mechanism for linear guide rail processing" with the national authorized patent number "CN216680352 U" is a relatively common drilling device. The patent points out that "during the drilling process, when the drilling needle descends to contact and drill the material, the positioning holes equally distributed along the inner wall of the top end of the positioning plate can limit the needle part of the drilling needle to prevent the drilling position from shifting and causing processing errors. When dealing with different drilling requirements and needs, through the threaded structure formed by the positioning plate and the screw on the carrier frame, the screw can be disassembled to separate the positioning plate from the carrier frame, and the positioning plate with different hole position spacings can be replaced according to production needs."

[0004] However, when positioning in this way, it is necessary to ensure that the drill bit is aligned with the hole position, and the operation is relatively troublesome. At the same time, when adjusting different spacings, it is also necessary to replace the positioning plate, which is cumbersome and time-consuming. In view of this, in response to the above problems, in-depth research has led to the generation of this case. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment: Please refer to Figures 1-4, A hole position positioning device for guide rail processing, including a base 1. At the middle position of the top end of the base 1, a support platform 7 is provided, and on both sides of the support platform 7, lifting platforms 2 are provided. The bottom ends of the lifting platforms 2 are fixed to the top end of the base 1. At the middle position of the top end of the base 1, a vertical frame 5 is installed, and at the top end of the vertical frame 5, a punching machine 8 is embedded. The output end of the punching machine 8 extends above the support platform 7. On both sides of the support platform 7, two mounting frames 6 are respectively provided, and the bottom end of one of the mounting frames 6 is fixed to the top end of the base 1. Inside the mounting frames 6, clamping components for fixing the guide rail are provided. Inside the base 1, a cavity 11 is opened, and inside the cavity 11, two second fixing plates 12 are provided. The top ends of the second fixing plates 12 are connected to the bottom end of the other mounting frame 6 through fixing parts. On one side inside the cavity 11, a stop bar 19 is provided, and on one side of the stop bar 19, an adjusting component for adjusting its position is provided;

[0022] At the front and rear ends of the mounting frame 6 with the second fixing plate 12 fixed at the bottom, first fixing plates 3 are provided, and the bottom ends of the first fixing plates 3 are fixed to the top end of the base 1. The connection mode between the mounting frame 6 and the first fixing plate 3 is a sliding connection;

[0023] Specifically, as Figure 1 , Figure 2 and Figure 3 shown, when the device is working, place the guide rail on the lifting platform 2, the mounting frame 6 and the support platform 7. The bottom end inside the mounting frame 6 is on the same horizontal plane as the lifting platform 2 and the support platform 7, which can make the guide rail placed stably. After the guide rail is placed, make the drilling hole position on the guide rail directly below the drill bit of the punching machine 8. Then, make the clamps on the two mounting frames 6 clamp and fix the guide rail. Then, use the punching machine 8 to perform the drilling operation. The punching machine 8 is a product in the prior art and can drive the drill bit to rotate and feed to complete the punching operation. When one punching is completed, the clamping of the right mounting frame 6 can be cancelled. Then, move the left mounting frame 6 until the second fixing plate 12 is blocked by the stop bar 19. At this time, make the right mounting frame 6 clamp the guide rail, cancel the clamping effect of the left mounting frame 6, and reset the left mounting frame 6. After the mounting frame 6 is reset, the previous clamping and punching operations can be repeated. In this way, each time after the guide rail is punched, the distance between the second fixing plate 12 and one side of the stop bar 19 can be moved, so as to complete the rapid positioning of multiple equally spaced punchings. Since the position of the stop bar 19 can be adjusted by means of the adjusting component, the punching spacing can be quickly adjusted.

[0024] The adjusting component includes a knob 16. The knob 16 is rotatably installed on one side of the base 1, and a rotating shaft 18 is fixed at the central position on one side of the knob 16. One end of the rotating shaft 18 extends into the interior of the cavity 11, and a moving strip 17 is sleeved on the outer wall of the rotating shaft 18 inside the cavity 11. Two connecting rods 20 are fixed on one side of the moving strip 17, and one end of each of the two connecting rods 20 is fixed to one side of the blocking strip 19;

[0025] The outer wall of the rotating shaft 18 is provided with external threads, and the inner wall of the moving strip 17 is provided with internal threads that match them;

[0026] Guide grooves are formed on the inner wall of the cavity 11, and guide blocks that are slidably matched with it are fixed at both ends of the moving strip 17;

[0027] Specifically, as Figure 1 and Figure 3 shown, rotating the knob 16 can drive the rotating shaft 18 to rotate. The rotating shaft 18 is in threaded cooperation with the moving strip 17. At the same time, the moving strip 17 is slidably matched with the cavity 11. Therefore, the moving strip 17 cannot rotate following the rotating shaft 18, so it can move directionally inside the cavity 11. By means of the connecting rod 20, the position of the blocking strip 19 is changed. The top of the base 1 can be embedded with a glass plate installed, and scales are marked on or near the glass plate. The user observes the position of the blocking strip 19 from the outside to judge the distance between the second fixing plate 12 and the blocking strip 19, which is convenient for adjustment.

[0028] The clamping component includes two first electric push rods 4. The two first electric push rods 4 are respectively fixed at both ends of the mounting frame 6, and the output ends of the first electric push rods 4 both extend into the interior of the mounting frame 6 and are installed with movable frames 9. The shape of the movable frame 9 is L-shaped, and second electric push rods 15 are installed at the tops of the movable frames 9. The output ends of the second electric push rods 15 extend below the movable frames 9 and are installed with pressing plates 10;

[0029] One side of the bottom end of the movable frame 9 is installed with a rotating roller 14 through a rotating shaft, and an annular groove 22 is formed at the bottom end of the outer wall of the rotating roller 14. A fixing strip 13 is fixed at the bottom of one side of the movable frame 9, and a plurality of rotating disks 21 are installed on one side of the fixing strip 13 through brackets, and one end of each of the plurality of rotating disks 21 extends into the interior of the groove 22;

[0030] Specifically, as Figure 1 and Figure 2As shown in the figure, when using the clamping assembly to clamp the guide rail, first start the first electric push rod 4 to push the movable frames 9 at both ends to move, so that the rotating rollers 14 press on the front and rear surfaces of the guide rail. While restricting the shaking of the guide rail, it can ensure that the guide rail can move relative to the clamping assembly without other restrictions. When further clamping is required, start the second electric push rod 15 to drive the pressing plate 10 to press down on the upper surface of the guide rail. It should be noted that here, the rotating disk 21 is matched with the groove 22 to ensure that the rotating roller 14 can rotate smoothly, so that the bottom end of the rotating roller 14 does not need to be connected by a shaft, and the bottom end of the movable frame 9 does not need to reserve materials for shaft matching, so that the movable frame 9 forms a perfect L shape instead of a C shape. In this way, the bottom end of the rotating roller 14 can be as close as possible to the bottom end inside the mounting frame 6 to adapt to more guide rails.

[0031] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
