Description

Technical Field

[0001] This utility model relates to the field of baking pan technology, specifically a baking pan drilling device for easy positioning. Background Technology

[0002] A baking tray is a metal product used for heating food. It is usually a thin sheet with reinforced edges or handles for carrying. To facilitate the subsequent installation of handles, screw connections, or accessories, holes are often drilled in the edge area.

[0003] While most common equipment for drilling holes in the edges of baking trays has simple pressure plates or side clamps, the clamping position and clamping force still require manual adjustment. It cannot automatically adjust the position of the positioning blocks according to the edge size of the baking tray, and repeated adjustments are required before each processing. This is not only time-consuming, but also prone to problems such as inadequate clamping, uneven clamping, and stopping errors. During the drilling process, the workpiece is prone to slight slippage or warping due to vibration, resulting in deviations in the hole position. This is especially true for baking trays with narrow edges or irregular structures, where errors are more likely to occur.

[0004] Therefore, there is an urgent need for a baking pan drilling device that is easy to position, in order to solve the above-mentioned technical defects. Utility Model Content

[0005] The purpose of this invention is to provide a baking pan drilling device that is easy to position, so as to solve the problems of misalignment, uneven clamping force and stopping error caused by manual clamping mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for a baking tray that is easy to position, comprising a mounting frame and a drilling platform. A servo motor is fixedly mounted at the bottom of the drilling platform. A transmission seat is fixedly connected upwards along the output axis of the servo motor. A rotating seat is fixedly sleeved on the outside of the transmission seat. Two sets of positioning blocks are respectively abutted on both sides of the rotating seat. Two sets of fixing rods are fixedly connected to the outside of each positioning block. A connecting seat is fixedly connected to the end of each fixing rod. A pad is welded to the inner side wall of the connecting seat. Holes are machined in the pads. A cylinder is fixedly connected between the two sets of positioning blocks. Screw rails are mounted on both sides of the top of the mounting frame. Drill bits are mounted on each screw rail. A cylinder is mounted at the middle position of the top of the mounting frame. A pressure plate is fixedly connected downwards to the piston rod of the cylinder.

[0007] As a further technical solution of this utility model, track plates are fixed on both sides of the inner wall of the drilling platform, and wedge-shaped blocks are machined at the bottom of each positioning block. The wedge-shaped blocks are embedded in the guide grooves on the surface of the track plates and slide.

[0008] As a further technical solution of this utility model, the positioning block has a trapezoidal structure, and the two sets of positioning blocks are symmetrically distributed with respect to the center point of the rotating seat.

[0009] As a further technical solution of this utility model, a control panel is installed on the outer wall of the drilling platform, and clamps are welded on both sides of the drilling platform, with a chip groove engaged inside the clamp.

[0010] As a further technical solution of this utility model, wall grooves are respectively opened on both sides of the outer wall of the drilling platform, and the fixing rod passes through the wall groove and extends to the outside of the drilling platform.

[0011] As a further technical solution of this utility model, the connecting seat and the fixing rod are fixedly connected by screws.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the easy-to-position baking pan plate drilling device not only improves the stability of the baking pan plate drilling process, but also solves the problems of inaccurate position and non-perpendicular angle in traditional manual drilling.

[0013] (1) By setting up a servo motor, rotary table, positioning block, wedge block, track plate, cylinder and pad, a dual positioning structure of "edge clamping + center pressing" is realized, which improves the stability of the baking tray during drilling and avoids the problems of misalignment, uneven clamping force and stop error caused by manual clamping.

[0014] (2) By setting up a screw guide rail, drill bit, hole position and pad, the drilling position is accurate and the verticality is high, preventing the drill bit from vibrating or deviating when penetrating the metal plate, effectively avoiding the problems of burrs, deviation or slippage caused by suspended drilling. It not only solves the problems of "inaccurate position" and "non-vertical angle" in traditional manual drilling, but also avoids the problems of over-drilling and accidental injury caused by untimely manual stopping.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides an embodiment of a baking tray drilling device for easy positioning, comprising a mounting frame 1 and a drilling platform 14. A servo motor 12 is fixedly mounted at the bottom of the drilling platform 14. A transmission seat 18 is fixedly connected upwards along the output axis of the servo motor 12. A rotating seat 17 is fixedly sleeved on the outside of the transmission seat 18. Two sets of positioning blocks 11 abut against each other on both sides of the rotating seat 17. Two sets of fixing rods 8 are fixedly connected to the outside of each positioning block 11. A connecting seat 7 is fixedly connected to the end of each fixing rod 8. The connecting seat 7 has a connecting rod 7 on its inner side. The wall is welded with a pad 6, and the pad 6 has holes 5 machined in it. A cylinder 19 is fixedly connected between two sets of positioning blocks 11. Screw slide rails 2 are installed on both sides of the top of the mounting frame 1. Drill bits 3 are installed at the screw slide rails 2. A cylinder 19 is installed in the middle of the top of the mounting frame 1. A pressure plate 4 is fixedly connected downward to the piston rod of the cylinder 19. Track plates 10 are fixed on both sides of the inner wall of the drill table 14. Wedge blocks 20 are machined at the bottom of the positioning blocks 11. The wedge blocks 20 are embedded in the guide grooves on the surface of the track plates 10 and slide.

[0022] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, the servo motor 12 is a medium inertia AC servo motor, and its output shaft is connected to the transmission seat 18 to drive the rotating seat 17 to rotate. The rotating seat 17 abuts against two sets of positioning blocks 11 on both sides. When the rotating seat 17 rotates, it can drive the positioning blocks 11 to move symmetrically left and right through its eccentric guide shape, thereby completing the clamping or loosening action of the baking tray. In order to ensure that the movement trajectory of the positioning blocks 11 is accurate and controllable, wedge blocks 20 are machined at the bottom end and slide in the guide groove on the surface of the track plate 10. The entire clamping process is linear and symmetrical clamping without deviation or jamming. The positioning blocks 11 are fixedly connected to the connecting seat 7 and the pad block 6. When the clamping action is performed, the pad block 6 fits against the edge of the baking tray and firmly positions the baking tray. At the same time, a standard double-acting cylinder 19 with a cylinder diameter of 50mm and a stroke of 100mm is installed on the upper part, which drives the pressure plate 4 to press down, forming a two-way positioning structure of upper pressure and lower clamping.

[0023] The positioning block 11 has a trapezoidal structure. The two sets of positioning blocks 11 are symmetrically distributed relative to the center point of the rotating seat 17. The outer walls of the drill platform 14 are respectively provided with wall grooves 9, and the fixing rod 8 passes through the wall grooves 9 and extends to the outside of the drill platform 14.

[0024] Specifically, such as Figure 1 and Figure 4 As shown, the ball screw slide 2 adopts a ball screw slide assembly, model SGS12-300B, which is arranged along both sides of the mounting frame 1 to form a front and rear movement channel. It is equipped with a slider platform inside to support the drill bit 3. The drill bit 3 is driven to move up and down by its own built-in cylinder to drill holes in the hole position 5 below. The drill bit 3 is equipped with an integrated micro brushless motor, which provides stable power output and is suitable for high-speed drilling of thin sheet metal workpieces. The pad 6 is located below the baking tray and cooperates with the hole position 5 to serve as a support surface during the drilling process, preventing the drill bit 3 from vibrating or deviating when penetrating the metal sheet.

[0025] A control panel 13 is installed on the outer wall of the drilling platform 14. Clamps 16 are welded on both sides of the drilling platform 14. A chip groove 15 is snapped into the clamp 16. The connecting seat 7 and the fixing rod 8 are fixedly connected by screws.

[0026] Specifically, such as Figure 1 As shown, a set of chip troughs 15 is provided directly below each set of pad blocks 6. The chip troughs 15 are clamped to both sides of the drill rig 14 by clamps 16, which facilitates installation and disassembly. The metal slag generated during drilling is collected in the chip troughs 15, which makes it easy for operators to clean up during processing intervals.

[0027] The computer software involved in the control panel 13 carrier in the technical solution is software technology known to those skilled in the art; it is merely applied to the aforementioned hardware carrier. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carrier, nor is it a key technical point of the invention.

[0028] Therefore, it can be seen that the “screw guide rail 2”, “drill bit 3”, “cylinder 19”, “servo motor 12” and other components involved in this application are all physical functional modules that combine computer software programs or protocols in the prior art with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction relationship between the various physical functional modules, that is, the improvement of the overall structure of this application, in order to solve the corresponding technical problems to be solved by this application.

[0029] Working principle: In use, place the baking tray on the surface of the drill rig 14 on top of the mounting bracket 1. After centering the position, start the device via the control panel 13. The servo motor 12 starts running, driving the transmission seat 18 to rotate the rotating seat 17 clockwise. Since there are two sets of positioning blocks 11 on both sides of the rotating seat 17, as the rotating seat 17 rotates, the two sets of positioning blocks 11 move symmetrically inward along the bottom track plate 10 under the steering thrust. The bottom of the positioning block 11 is embedded in the guide groove of the track plate 10. The wedge block 20 restricts its linear displacement to ensure the synchronicity and accuracy of the clamping action. The connecting seat 7 connected to the positioning block 11 is pushed inward, so that the part with the welded pad 6 is close to the edge of the baking tray, clamping it firmly. Then, the cylinder 19 above is activated, and the piston rod pushes downward. The moving pressure plate 4 applies vertical downward pressure to the center of the baking tray. After it is stabilized, the two sets of lead screw slides 2 on the left and right drive the drill bit 3 mounted on them to move back and forth, so that the drill bit 3 is precisely aligned with the hole 5 on the pad block 6. The built-in cylinder of the drill bit 3 presses down and drives the drill bit 3 to drill vertically into the hole 5 to complete the drilling operation. During the drilling process, the built-in brushless motor of the drill bit 3 provides stable power. During the drilling process, since there is a chip groove 15 below the hole 5, metal chips can fall into the groove and be collected, avoiding the accumulation of chips in the drilling area. After the operation is completed, the servo motor 12 drives the rotary seat 17 to reset in the reverse direction, and the positioning block 11 moves outward to drive the pad block 6 to release the workpiece. At the same time, the cylinder 19 drives the pressure plate 4 to rise, and the entire drilling operation is completed. The operator can take out the drilled baking tray and place the next one.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
