Description

Technical Field

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

[0002] An engine mount, also known as an engine base or engine support frame, is a structural component used to fix and support an engine. Its function is to mount the engine on the chassis or body of vehicles such as cars, airplanes, and ships, while reducing engine vibration and noise and ensuring engine stability during operation. During the production process of engine mounts, drilling equipment is usually required to drill holes in the mount to meet the requirements.

[0003] Chinese patent discloses a drilling mechanism for automobile engine bracket production (authorization announcement number CN216758240U). This patented technology places the bracket requiring drilling between two side fixing components. The bracket is clamped and fixed by second transmission belts on both sides. Under the transmission action of the first and second transmission belts, the bracket requiring drilling moves below the drilling components, where drilling is performed. After drilling is completed, the transmission action of the first and second transmission belts disengages from the other side, thus completing the drilling process for the entire bracket. This invention, through multiple transmission devices, streamlines the drilling process of the bracket, thereby improving the efficiency of drilling.

[0004] However, most existing engine mounts use belt drive for movement, resulting in poor stability and slow adjustment during clamping. For example, the aforementioned comparative document uses a belt drive, which can cause misalignment during transport, affecting drilling. Furthermore, manual clamping adjustment is still required after reaching the drilling position, making it impractical. Therefore, those skilled in the art have provided a drilling device for engine mount production to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a drilling device for the production of engine brackets, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for engine bracket production, comprising: a base and a bracket mounted on the upper surface of the base; a first cylinder is mounted on the upper surface of the bracket; the telescopic end of the first cylinder passes through the lower surface of the bracket and is connected to a drilling mechanism; a placement plate is slidably mounted on the upper surface of the base; suction holes are symmetrically opened on the upper surface of the placement plate; a vacuum pump is mounted on the front surface of the placement plate; a second cylinder is mounted on the outer side of the base; a moving groove is opened on the upper surface of the base; a moving plate is arranged inside the moving groove on the lower surface of the placement plate; and guide rods are symmetrically arranged inside the moving groove.

[0007] As a further technical solution of this utility model, the fixed end of the second cylinder is installed on the outside of the base, and the telescopic end of the second cylinder passes through the inside of the moving groove and is connected to one side of the moving plate.

[0008] As a further technical solution of this utility model, the interior of the movable plate is provided with a guide hole for guiding the movable plate, and the movable plate is slidably mounted on the outside of the two guide rods.

[0009] As a further technical solution of this utility model, at least four adsorption holes are symmetrically opened on the upper surface of the placement plate, a vacuum hood is provided inside the placement plate below the adsorption holes, and a connecting pipe is connected to the air inlet end of the vacuum pump.

[0010] As a further technical solution of this utility model, the rear end of the connecting tube penetrates the front surface of the placement plate and communicates with the interior of the vacuum hood, and the adsorption hole is a circular hole on the upper surface of the placement plate.

[0011] As a further technical solution of this utility model, the guide rod is cylindrical and there are two symmetrically arranged inside the moving groove, and the two guide rods are the same size.

[0012] This utility model provides a drilling device for the production of engine brackets, which has the following advantages compared with the prior art:

[0013] 1. This design provides a drilling device for engine bracket production. The operation of the second cylinder causes the moving plate to move inside the moving groove, that is, the moving plate slides outside the two guide rods. This allows the engine bracket on the mounting plate to be moved to different positions for drilling. The device has a simple structure, runs smoothly, and can achieve efficient drilling.

[0014] 2. This design provides a drilling device for engine bracket production. By using a vacuum pump, air is drawn in through the suction hole and then extracted through the vacuum cover and connecting pipe. This allows the engine bracket placed on the mounting plate to be suctioned and fixed in place, ensuring its stability and preventing it from moving and affecting the drilling process.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3This utility model provides a drilling device for engine bracket production, comprising: a base 1 and a bracket 12 mounted on the upper surface of the base 1. A first cylinder 2 is mounted on the upper surface of the bracket 12. The telescopic end of the first cylinder 2 passes through the lower surface of the bracket 12 and is connected to a drilling mechanism 21. A placement plate 3 is slidably mounted on the upper surface of the base 1. Adsorption holes 31 are symmetrically opened on the upper surface of the placement plate 3. A vacuum pump 4 is mounted on the front surface of the placement plate 3. A second cylinder 5 is mounted on the outer side of the base 1. A moving groove 11 is opened on the upper surface of the base 1. A moving plate 32 is set inside the moving groove 11 on the lower surface of the placement plate 3. Guide rods 51 are symmetrically arranged inside the moving groove 11. This arrangement allows the moving plate 32 to slide inside the moving groove 11 by the operation of the second cylinder 5. This allows the position of the placement plate 3 to be adjusted to adjust the position of the engine bracket. The operation of the vacuum pump 4 allows air to be drawn through the adsorption holes 31 to adsorb and fix the engine bracket, ensuring its stability and facilitating drilling.

[0021] like Figure 2 As shown, the fixed end of the second cylinder 5 is installed on the outside of the base 1, and the telescopic end of the second cylinder 5 passes through the inner side of the moving groove 11 and is connected to one side of the moving plate 32. This arrangement utilizes the operation of the second cylinder 5 to make the moving plate 32 slide inside the moving groove 11, so that the position of the placement plate 3 can be automatically adjusted to adjust the position of the engine bracket, so as to facilitate drilling work on the engine bracket.

[0022] like Figure 2 and Figure 3 As shown, the movable plate 32 has a guide hole 321 inside for guiding the movable plate 32. The movable plate 32 is slidably mounted on the outside of two guide rods 51. The guide rods 51 are cylindrical and are symmetrically arranged inside the movable groove 11. The two guide rods 51 are the same size. This arrangement, through the opening of the guide hole 321, enables the guide rods 51 to guide the movable plate 32 to slide outside the two guide rods 51, thus ensuring the stability of the placement plate 3 when moving.

[0023] like Figure 3 As shown, at least four adsorption holes 31 are symmetrically opened on the upper surface of the placement plate 3. A vacuum hood 41 is set inside the placement plate 3 below the adsorption holes 31. The air inlet end of the vacuum pump 4 is connected to a connecting pipe 42. The rear end of the connecting pipe 42 passes through the front surface of the placement plate 3 and communicates with the interior of the vacuum hood 41. The adsorption holes 31 are circular holes on the upper surface of the placement plate 3. When the engine bracket is placed on the placement plate 3, the air inside the adsorption holes 31 can be drawn out through the vacuum hood 41 and the connecting pipe 42 and discharged to the outside by starting the vacuum pump 4. In this way, a vacuum can be drawn under the engine bracket to ensure its stability and facilitate drilling.

[0024] The working principle of this utility model is as follows: When using the drilling device for engine bracket production, the engine bracket to be drilled is first placed on the placement plate 3. After placement, the vacuum pump 4 is started, which causes the air inside the adsorption hole 31 to be extracted through the vacuum cover 41 and the connecting pipe 42 and discharged to the outside. This creates a vacuum under the engine bracket to ensure its stability and facilitate drilling. After adsorption and fixation, the operation of the second cylinder 5 causes the moving plate 32 to move inside the moving groove 11, that is, the moving plate 32 slides outside the two guide rods 51. This allows the engine bracket on the placement plate 3 to be moved to different positions. The operation of the first cylinder 2 causes the drilling mechanism 21 to move down to drill the engine bracket. The structure is simple, the operation is stable, and efficient drilling can be achieved.

[0025] The first cylinder, the second cylinder, and the vacuum pump used in this invention are all existing known electrical devices, and all can be purchased and used directly on the market. Their structure, circuit, and control principle are all existing known technologies. Therefore, the structure, circuit, and control principle of the device will not be described in detail here.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
