Description

Technical Field

[0001] This utility model relates to the field of drilling positioning technology, and in particular to a positioning bracket for drilling assistance. Background Technology

[0002] Positioning brackets used for drilling assistance are common auxiliary tools in fields such as machining, construction, and equipment installation. Their core function is to ensure the accuracy and verticality of the drilling position through physical positioning and fixation, thereby avoiding hole position displacement caused by shaking or error during manual operation, and facilitating subsequent operations.

[0003] A drilling auxiliary positioning structure for aluminum profile processing, with announcement number CN222243751U, includes: a double-headed hydraulic push rod and a drive motor at the bottom of a support base; a positioning plate on the surface of the support base; a positioning wheel inside the positioning plate; a traction belt on the surface of the positioning wheel; a moving screw inside the support plate; and a drilling device below the moving screw. The advantages are: firstly, the double-headed hydraulic push rod can be activated to displace the two sets of positioning plates, thereby clamping and positioning the aluminum profile using the clamping action of the two sets of positioning plates. Then, the aluminum profile can be drilled using the drilling device. When drilling is required at other locations on the aluminum profile, the drive motor can be activated to rotate the positioning wheel, thereby rotating the traction belt and moving the positioned aluminum profile, thus facilitating drilling of the moved aluminum profile using the drilling device.

[0004] However, the above-mentioned drilling auxiliary positioning structure for aluminum profile processing still has the following defects when used: When the above-mentioned existing technology is used, since the drilling equipment is fixedly connected to the lifting end of the electric push rod, it can only drill a single type of hole on the workpiece, which results in low practicality and great limitations. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning bracket for drilling assistance, so as to solve the problem mentioned in the background art that the existing positioning brackets for drilling assistance are inconvenient to use when changing to different models of drilling machines.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a positioning bracket for drilling assistance, comprising a bracket platform and a support frame, wherein the support frame is welded to the top of the bracket platform;

[0007] The support frame is equipped with an adjusting motor, and an adjusting rod is fixed to one side of the adjusting motor. An adjusting block is adjusted to the outside of the adjusting rod, and a hydraulic cylinder is fixed to the bottom of the adjusting block. A fixing block is fixed to the bottom of the hydraulic cylinder, and a guide groove is opened inside the fixing block. A guide block is slidably arranged inside the guide groove. Fixing mechanisms are provided on both sides of the fixing block. A protective frame is fixed to the bottom of the guide block, and a drilling machine is installed inside the protective frame. Electric push rods are fixed to both sides of the top of the support platform, and a positioning plate is provided on one side of each electric push rod. A limit mechanism is provided inside the support platform.

[0008] When using a positioning bracket for drilling assistance according to this technical solution, the fixed mechanism facilitates the replacement of different models of drilling machines under the action of guide blocks and guide grooves, so as to drill different types of holes, thereby improving its practicality.

[0009] Furthermore, the fixing mechanism includes a mounting block, which is disposed on one side of the fixing block. A baffle is slidably disposed inside the mounting block, and a fixing rod is fixed on one side of the baffle. A pull rod is fixed on the other side of the baffle. A return spring is evenly wound around the outside of the pull rod, and one end of the return spring is fixedly connected to the baffle, while the other end of the return spring is fixedly connected to the inner wall of the mounting block.

[0010] Furthermore, two reset springs are provided, and both reset springs are in a stretched state inside the mounting block.

[0011] Furthermore, there are two fixing rods, which are symmetrically distributed, and each of the two fixing rods has a fixing groove on the outer side of one end, and the fixing groove is opened inside the guide block.

[0012] Furthermore, there are two fixing rods, which are symmetrically distributed, and each of the two fixing rods has a fixing groove on the outer side of one end, and the fixing groove is opened inside the guide block.

[0013] Furthermore, the slider slides on the slide rod, and the fixing frame is slidably connected to the support platform through the slider and the slide rod.

[0014] Furthermore, the limiting plate has a rectangular cross-section, and a protective pad is adhered to the bottom end of the limiting plate. The protective pad is made of rubber.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the positioning bracket for drilling assistance not only facilitates the replacement of different models of drilling machines, but also has the function of upper and lower limit positioning;

[0016] By pulling the lever, the fixed rod is retracted into the mounting block under the action of the baffle, which facilitates the release of the guide block's limit and pushes the protective frame so that the guide block is inside the guide groove, making it easy to disassemble and replace the protective frame, and consequently, to disassemble and replace the drilling machine. Through the above operations, different models of drilling machines can be replaced according to the actual use, thereby drilling different types of holes in the workpiece and improving its practicality.

[0017] By activating the servo motor, the moving block moves horizontally under the action of the adjusting shaft, and the fixed frame moves synchronously under the action of the slider and slide rod. This allows the position of the limiting plate to be adjusted according to the actual usage. After adjustment, the hydraulic push rod is activated to make the limiting plate move downward until one side of the limiting plate and the side of the workpiece to be drilled are in contact with each other. The above operation facilitates the upper and lower limiting of the workpiece, thereby improving the positioning firmness, preventing the workpiece from moving, and thus improving the drilling effect.

[0026] Please see Figures 1-5 An embodiment of this utility model provides a positioning bracket for drilling assistance, including a bracket platform 1 and a support frame 6. The support frame 6 is welded to the top of the bracket platform 1. An adjusting motor 11 is provided inside the support frame 6. An adjusting rod 8 is fixed to one side of the adjusting motor 11. An adjusting block 9 is adjusted to the outside of the adjusting rod 8. A hydraulic cylinder 10 is fixed to the bottom of the adjusting block 9. A fixing block 14 is fixed to the bottom of the hydraulic cylinder 10. A guide groove 15 is opened inside the fixing block 14. A guide block 12 is slidably arranged inside the guide groove 15. Fixing mechanisms 7 are provided on both sides of the fixing block 14.

[0027] The fixing mechanism 7 includes a mounting block 701, which is disposed on one side of the fixing block 14. A baffle 704 is slidably disposed inside the mounting block 701. A fixing rod 705 is fixed on one side of the baffle 704, and a pull rod 703 is fixed on the other side of the baffle 704. A return spring 702 is evenly wound around the outside of the pull rod 703. One end of the return spring 702 is fixedly connected to the baffle 704, and the other end of the return spring 702 is fixedly connected to the inner wall of the mounting block 701.

[0028] There are two reset springs 702, and both reset springs 702 are in a stretched state inside the mounting block 701;

[0029] There are two fixing rods 705, which are symmetrically distributed. Each fixing rod 705 has a fixing groove on the outer side of one end, and the fixing groove is opened inside the guide block 12.

[0030] Specifically, such as Figure 1 , Figure 3 , Figure 4 As shown, during use, by pulling the lever 703, the fixing rod 705 is retracted into the mounting block 701, so as to release the limit on the guide block 12. Through the above operation, it is convenient to replace different models of drilling machines 4 according to the actual use, thereby improving its practicality.

[0031] A protective frame 5 is fixed at the bottom of the guide block 12, and a drilling machine 4 is installed inside the protective frame 5. Electric push rods 2 are fixed on both sides of the top of the support platform 1, and a positioning plate 3 is installed on one side of each electric push rod 2. A limit mechanism 13 is installed inside the support platform 1.

[0032] The limiting mechanism 13 includes a servo motor 1307, which is located inside the support platform 1. An adjustment shaft 1303 is fixed on one side of the servo motor 1307. A moving block 1302 is sleeved on the outside of the adjustment shaft 1303. A fixed frame 1304 is fixed at the top of the moving block 1302. A hydraulic push rod 1301 is fixed at the bottom of the fixed frame 1304. A limiting plate 1308 is provided at the bottom of the hydraulic push rod 1301. A slider 1306 is fixed on one side of the bottom of the fixed frame 1304. A sliding rod 1305 passes through the inside of the slider 1306.

[0033] The slider 1306 slides on the slide rod 1305, and the fixed frame 1304 is slidably connected to the support platform 1 through the slider 1306 and the slide rod 1305;

[0034] The limit plate 1308 has a rectangular cross-section, and a protective pad is attached to the bottom of the limit plate 1308. The protective pad is made of rubber.

[0035] Specifically, such as Figure 2 , Figure 3 , Figure 5 As shown, during use, by starting the servo motor 1307, the fixed frame 1304 moves horizontally under the action of the adjusting shaft 1303 and the moving block 1302, which facilitates the adjustment of the position of the limit plate 1308. With the cooperation of the hydraulic push rod 1301, it is easy to limit the workpiece that needs to be drilled to the upper and lower positions, thereby preventing it from moving in position.

[0036] Working Principle: In use, when drilling is required, the workpiece is placed on the support platform 1. Two electric push rods 2 are activated, causing two positioning plates 3 to move horizontally relative to each other, facilitating left-right positioning of the workpiece. Simultaneously, the servo motor 1307 is activated, causing the adjusting shaft 1303 to rotate. This rotation of the adjusting shaft 1303 causes the moving block 1302 to move horizontally, resulting in synchronized movement of the fixed frame 1304. This, in turn, causes the slider 1306 to slide on the sliding rod 1305. The slider... On the one hand, 1306 can limit the movement of the fixed frame 1304 to prevent it from shifting in position. On the other hand, it can also guide the movement of the fixed frame 1304 to improve its stability during movement. When the fixed frame 1304 moves to the designated position, the hydraulic push rod 1301 is activated to make the limiting plate 1308 move downward until one side of the limiting plate 1308 and one side of the workpiece are in contact with each other. The above operation facilitates the upper and lower limit of the fixed frame 1304, thereby avoiding hole position shift caused by shaking or error during manual operation and ensuring the accuracy of the drilling position.

[0037] Then, when it is necessary to change to a different model of drilling machine 4, the pull rod 703 is pulled to make the baffle 704 move horizontally. While the baffle 704 is moving horizontally, it squeezes the return spring 702, causing the return spring 702 to be compressed by the squeezing force. At the same time, the baffle 704 drives the fixing rod 705 to move synchronously until the fixing rod 705 is retracted into the mounting block 701, thereby releasing the limit on the guide block 12, and then facilitating the push of the protective frame 5, so that the guide block 12 moves away from the guide groove 1. 5. The above operation facilitates the disassembly of the drilling machine 4, and pushes the new drilling machine 4 to insert the guide block 12 into the guide groove 15 until the guide block 12 and the guide groove 15 are fully engaged. Then, the pull rod 703 is released, so that the force of the return spring 702 is eliminated, and then the baffle 704 is pushed to move horizontally until the fixing rod 705 is inserted into the guide block 12. The above operation facilitates the replacement of different models of drilling machines 4 according to the actual use, so as to drill different types of holes in the workpiece, thereby improving its flexibility.
