Description

Technical Field

[0001] This utility model belongs to the field of automatic drilling machine technology, and specifically relates to an automatic drilling fixture. Background Technology

[0002] An automatic drilling machine is a mechanical device that can automatically complete drilling tasks. It integrates mechanical, electrical, and control technologies and can be widely used in various manufacturing fields, greatly improving the efficiency, accuracy, and consistency of drilling processes while reducing labor costs and intensity. An automatic drilling fixture is a device specifically designed to fix and guide the drill bit during drilling operations, ensuring the stability and accuracy of the drill bit during the drilling process, thereby improving processing efficiency and hole quality.

[0003] Existing automatic drilling fixtures are cumbersome to operate, requiring manual adjustment of bolt positions to accommodate different workpiece sizes. Each time a workpiece is changed, the bolts must be retightened, which is time-consuming and labor-intensive. Furthermore, they have low compatibility, only able to clamp regular-shaped workpieces, and are unstable when clamping curved or irregular-shaped workpieces, which can easily lead to drilling deviation. Therefore, we propose an automatic drilling fixture. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic drilling fixture to solve the problem mentioned in the background art that the automatic drilling fixture cannot adaptively clamp according to the workpiece.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic drilling fixture, comprising a base, a drilling mechanism fixed to the top of the base, a worktable fixed to the top of the base relative to the bottom of the drilling mechanism, an adaptive clamping mechanism provided at the top of the worktable, and a drilling anti-splash mechanism provided at the top of the base, the adaptive clamping mechanism comprising: an adaptive clamping component and an auxiliary clamping and pressing component.

[0006] Preferably, the adaptive clamping assembly includes a fixing plate symmetrically fixed to the top of the worktable and a clamping plate symmetrically arranged inside the fixing plate, with a soft pad symmetrically fixed to one side of the clamping plate.

[0007] Preferably, the inner side of the fixing plate is symmetrically provided with telescopic holes and telescopic rods symmetrically fixed on the other side of the clamping plate. The telescopic rods are slidably connected to the telescopic holes, and a telescopic spring is sleeved on the surface of the telescopic rods relative to the clamping plate and the fixing plate.

[0008] Preferably, the auxiliary clamping and pressing assembly includes auxiliary clamping side plates symmetrically arranged on the other side of the clamping plate. A sliding groove is provided on the other side of the clamping plate. A slider is fixed on one side of the auxiliary clamping side plate. The slider is slidably connected to the sliding groove. Guide grooves are symmetrically provided on the inner wall of the sliding groove. Guide blocks are symmetrically fixed on both sides of the slider. The guide blocks are engaged with the guide grooves.

[0009] Preferably, cylinders are symmetrically fixed to the top of the clamping plate, and a hydraulic rod connected to the auxiliary clamping side plate is provided inside the end of the cylinder.

[0010] Preferably, the inner side of the auxiliary clamping side plate is provided with a groove, and the inside of the auxiliary clamping side plate is provided with a clamping block embedded in the groove. A built-in spring rod passing through the end of the clamping block is fixed inside the groove.

[0011] Preferably, the drilling anti-splash mechanism includes an anti-splash frame fixed to the top of the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes a telescopic rod and a telescopic spring to form an elastic clamping assembly, allowing the clamping plate to move laterally and automatically adapt to the workpiece width. Furthermore, a designed auxiliary clamping side plate, driven by a cylinder, slides longitudinally along a hydraulic rod. Combined with a slider and a guide groove structure, it achieves adaptive clamping of the workpiece length. Finally, a pressure block, elastically reset via a built-in spring rod, utilizes a beveled surface design to automatically lift and press down to lock upon contact with the workpiece, preventing damage to the workpiece surface and thus achieving the function of assisting in workpiece clamping. Compared to existing technologies, this invention greatly facilitates workpiece clamping. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: an automatic drilling fixture, including a base 1, a drilling mechanism 2 fixed at the top of the base 1, a worktable 3 fixed at the top of the base 1 relative to the bottom of the drilling mechanism 2, an adaptive clamping mechanism at the top of the worktable 3, and a drilling anti-splash mechanism at the top of the base 1. The adaptive clamping mechanism includes an adaptive clamping component and an auxiliary clamping and pressing component.

[0021] In this embodiment, preferably, the adaptive clamping assembly includes a fixing plate 100 symmetrically fixed to the top of the workbench 3 and a clamping plate 101 symmetrically arranged inside the fixing plate 100, with a soft pad 102 symmetrically fixed on one side of the clamping plate 101.

[0022] In this embodiment, preferably, the inner side of the fixing plate 100 is symmetrically provided with telescopic holes 200 and telescopic rods 201 symmetrically fixed on the other side of the clamping plate 101. The telescopic rods 201 are slidably connected to the telescopic holes 200. A telescopic spring 202 is sleeved on the surface of the telescopic rods 201 and between the clamping plate 101 and the fixing plate 100, which can clamp the width of the workpiece.

[0023] In this embodiment, preferably, the auxiliary clamping and pressing assembly includes auxiliary clamping side plates 300 symmetrically arranged on the other side of the clamping plate 101. A sliding groove 301 is provided on the other side of the clamping plate 101. A slider 302 is fixed on one side of the auxiliary clamping side plate 300. The slider 302 is slidably connected to the sliding groove 301. A guide groove 303 is symmetrically provided on the inner wall of the sliding groove 301. Guide blocks 304 are symmetrically fixed on both sides of the slider 302. The guide blocks 304 are engaged with the guide groove 303 to facilitate clamping the length of the workpiece.

[0024] In this embodiment, preferably, cylinders 400 are symmetrically fixed at the top of the clamping plate 101, and a hydraulic rod 401 connected to the auxiliary clamping side plate 300 is provided in the end of the cylinder 400, so as to facilitate the sliding of the auxiliary clamping side plate 300.

[0025] In this embodiment, preferably, a groove 500 is provided on the inner side of the auxiliary clamping side plate 300, and a clamping block 501 is provided inside the auxiliary clamping side plate 300 and embedded in the groove 500. An internal spring rod 502 that passes through the end of the clamping block 501 is fixed inside the groove 500, which can clamp the workpiece.

[0026] In this embodiment, preferably, the drilling anti-splash mechanism includes an anti-splash frame 600 fixed to the top of the base 1. The anti-splash frame 600 directly surrounds the working area, effectively blocking the spread of flying debris and keeping the environment clean.

[0027] The working principle and usage process of this utility model are as follows: When a workpiece needs to be clamped, the clamping plate 101 is first pulled, causing the telescopic rod 201 to slide inside the telescopic hole 200, compressing the telescopic spring 202 and causing it to deform. This allows the clamping plate 101 to move towards the fixed plate 100. The workpiece is then placed at the top of the worktable 3, relative to the inner side of the two clamping plates 101. The clamping plate 101 is then released, allowing the telescopic rod 201 to return to its original position within the telescopic hole 200 under the action of the telescopic spring 202. This causes the two clamping plates 101 to return to their original position, clamping both sides of the workpiece. Then, the cylinder 400 is activated, causing the hydraulic rod 401 to retract. This simultaneously causes the auxiliary clamping side plate 300 to slide inside the clamping plate 101 and the slider 302 to slide inside the groove 301. Simultaneously, the guide block 304 slides inside the guide groove 303 to provide a guiding function. When the auxiliary clamping side plate 300 is about to fit with both ends of the workpiece, the clamping block 501 is pre-released. Through the inclined surface at the lower end of the clamping block 501, under the action of force, the clamping block 501 can be squeezed to move upward inside the groove 500, causing the built-in spring rod 502 to deform. Then, the auxiliary clamping side plate 300 can be used to clamp the two ends of the workpiece. Under the action of the built-in spring rod 502, the clamping block 501 returns to its original position and slides inside the groove 500, allowing the bottom end of the clamping block 501 to press against the top end of the workpiece. Then, the drilling mechanism 2 can be used to drill holes in the workpiece. The flying chips generated during drilling can be prevented from flying around by the anti-splash frame 600 at the top of the base 1.

[0028] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
