Description

Technical Field

[0001] This utility model relates to the field of drilling machine technology, specifically to a drilling device for processing acrylic glass. Background Technology

[0002] A drilling device for acrylic glass processing is a specialized piece of equipment used for drilling holes in acrylic glass. It is a relatively common type of drilling device. It has a fixed worktable and an adjustable drill bit. A motor drives the drill bit to rotate, and the cutting action of the drill bit creates holes in the acrylic glass.

[0003] Existing drilling devices for acrylic glass processing typically use several rubber rollers mounted on the drilling machine's platform to facilitate glass movement. However, due to the elasticity and rolling nature of these rollers, even if the glass is initially positioned accurately, the rolling action makes it difficult to maintain a fixed position during drilling. Even slight displacements can lead to positional deviations and affect processing accuracy. Furthermore, the contact between the drill bit and the glass generates impact and friction during drilling, which can cause the glass to move or wobble on the rubber rollers. This displacement is particularly noticeable when drilling deep or high-precision holes. The acrylic glass's support on the rolling rollers is less stable than a fixed platform. Uneven weight distribution and external vibrations can cause the glass to wobble, affecting not only drilling quality but also potentially leading to drill bit breakage or damage to the acrylic glass.

[0004] Therefore, it is necessary to invent a drilling device for processing plexiglass to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a drilling device for processing acrylic glass, so as to solve the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drilling device for processing plexiglass, comprising a base, an organic head fixedly mounted above the tail end of the base, a platform above the front end of the base, a pressure plate below the front end of the organic head, the pressure plate being sleeved around the drill bit below the organic head, and a support mechanism being provided on the platform.

[0007] The supporting structure includes:

[0008] Multiple support seats are disposed on the platform. At both ends of each support seat and on the outer side of both ends of the platform, a cylinder is horizontally fixedly installed. A ball bearing is rotatably installed on the upper surface of each support seat.

[0009] Each of the support bases has rollers installed at both ends of its bottom, and a wedge block is provided below each roller. The wedge blocks below the two rollers are distributed opposite to each other, and the tail end of each wedge block is fixedly connected to the output end of the corresponding cylinder.

[0010] As a preferred embodiment of this utility model, the platform is located directly below the drill bit at the front end of the machine head. Every two relative cylinders form a group, and every two relative wedge blocks form a group. Each group of wedge blocks and each group of cylinders have a corresponding support seat, and the inclined surface of each wedge block is in contact with the surface of the corresponding roller.

[0011] As a preferred embodiment of this utility model, the upper surface of the platform is provided with a guide groove, each of the support seats is respectively disposed above the corresponding guide groove, the output end of each group of cylinders penetrates the inner walls of both ends of the platform, and each group of wedge blocks is located at the inner ends of the corresponding guide groove.

[0012] As a preferred embodiment of this utility model, the bottom of the wedge block is slidably connected to the lower surface of the guide channel, both ends of the guide channel are provided with drain outlets, and drain pipes are fixedly installed at the bottom of both ends of the guide channel, and the drain pipes are connected to the corresponding drain outlets.

[0013] As a preferred embodiment of this utility model, the tail end of the pressure plate is fixedly connected to the bottom of the front end of the machine head through a connector. The middle position of the pressure plate is a circular hollow structure. A water outlet is opened inside the front end of the pressure plate. A water inlet connector is connected to one end of the front end of the pressure plate and the water outlet. The water inlet connector is connected to a water supply device through a conduit.

[0014] As a preferred embodiment of this utility model, a waterproof cover is installed on the top of the pressure plate, and multiple protrusions are fixedly installed on the bottom of the waterproof cover. The multiple protrusions are adapted to and connected with the corresponding slots on the upper surface of the pressure plate. The middle part of the waterproof cover is a hollow structure, and the waterproof cover is sleeved on the outside of the drill bit.

[0015] As a preferred embodiment of this utility model, an annular sealing ring is fixedly installed inside the lower part of the middle gap of the pressure plate, and the sealing ring, the waterproof cover and the middle part of the pressure plate do not come into contact with the drill bit.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. By setting a support mechanism in the guide groove of the table, the support seat in the support mechanism is located in the corresponding guide groove. The roller is pushed by the cylinder and wedge block to realize the lifting and lowering of the support seat. When the glass is moved, the ball bearings on the upper surface of the support seat can contact the glass for easy movement. When the glass is not moved, the support seat is lowered and the ball bearings do not contact the glass. The glass is supported by the upper surface of the table. This structure with switchable support mode greatly enhances the stability of the glass when drilling.

[0018] 2. By installing a pressure plate on the outside of the drill bit, and installing a water inlet connector and a waterproof cover on the pressure plate, cooling water can be directly supplied during the drilling process of the drill bit into the glass. This avoids the existing method of spraying cooling water with a nozzle. Combined with the waterproof cover, it effectively prevents the problem of the sprayed cooling water splashing everywhere under the high-speed rotation of the drill bit during the drilling process.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-5 The device shown is a drilling device for processing plexiglass, including a base 1, a drill head 2 fixedly installed on the upper part of the tail end of the base 1, a platform 3 provided on the upper part of the front end of the base 1, a pressure plate 5 provided on the lower part of the front end of the drill head 2, the pressure plate 5 being sleeved on the outside of the drill bit below the drill head 2, and a support mechanism 4 provided on the platform 3.

[0029] Supporting mechanism 4 includes:

[0030] Multiple support seats 41 are set on the platform 3. At both ends of each support seat 41 and at both ends of the platform 3, a cylinder 44 is horizontally fixedly installed. A ball bearing 42 is rotatably installed on the upper surface of each support seat 41.

[0031] Each support base 41 has a roller 43 installed at both ends of its bottom. Each roller 43 has a wedge block 45 below it. The wedge blocks 45 below the two rollers 43 are distributed opposite to each other. The tail end of each wedge block 45 is fixedly connected to the output end of the corresponding cylinder 44.

[0032] In this example, the base 1 serves as the fundamental support component of the entire drilling device, providing a stable mounting platform for other components such as the drill head 2 and the platform 3, ensuring the overall stability of the device. The drill head 2 is fixedly mounted above the tail end of the base 1, used to mount and fix the drill bit, and to provide a power source for the drill bit, enabling it to rotate at high speed and perform drilling operations on the acrylic glass. The platform 3 is located directly below the drill bit at the front end of the drill head 2, serving as the working platform for placing the acrylic glass. Multiple support seats 41 are mounted on the platform 3 to support the acrylic glass. Ball bearings 42 are rotatably mounted on the upper surface of the support seats 41. When the glass needs to be moved, the ball bearings 42 contact the glass; due to the low rolling friction of the ball bearings, the glass moves easily on the platform 3. When the glass is not moved, the support seats 41 are lowered by the action of the cylinder 44 and the wedge block 45, and the ball bearings 42 do not contact the glass. The upper surface of the platform 3 supports the glass, improving the stability of the glass during drilling.

[0033] Furthermore, in the above technical solution, the platform 3 is located directly below the drill bit at the front end of the head 2. Every two opposing cylinders 44 form a group, and every two opposing wedge blocks 45 form a group. Each group of wedge blocks 45 and each group of cylinders 44 corresponds to a support seat 41, and the inclined surface of each wedge block 45 is in contact with the surface of the corresponding roller 43.

[0034] In this example, the cylinder 44 controls the extension and retraction of its output end to push the wedge block 45 to move. The forward and backward movement of the wedge block 45 abuts against the rollers 43 at both ends of the bottom of the support base 41, thereby achieving the lifting and lowering control of the support base 41. The inclined surface of the wedge block 45 contacts the surface of the rollers 43. When the cylinder 44 pushes the wedge block 45 to move, the inclined surface of the wedge block 45 acts on the rollers 43, lifting the rollers 43 upward, causing the support base 41 to rise or fall, realizing the lifting and lowering function of the support base 41, and thus realizing the switching of the glass support method.

[0035] Furthermore, in the above technical solution, the upper surface of the platform 3 is provided with a guide groove 31, each support seat 41 is respectively set above the corresponding guide groove 31, the output end of each set of cylinders 44 penetrates through the inner walls of both ends of the platform 3, and each set of wedge blocks 45 is located at the inner ends of the corresponding guide groove 31.

[0036] Furthermore, in the above technical solution, the bottom of the wedge block 45 is slidably connected to the lower surface of the guide channel 31, both ends of the guide channel 31 are provided with drain ports, and both ends of the guide channel 31 are fixedly installed with drain pipes 32, and the drain pipes 32 are connected to the corresponding drain ports.

[0037] In this example, a guide channel 31 is provided on the upper surface of the table 3. The guide channel 31 is used to collect debris and coolant generated during the drilling process and discharge them through the drain outlets and drain pipes 32 at both ends, keeping the working environment clean and preventing debris and coolant from affecting glass processing. In addition, the table 3 also provides a mounting base for the support mechanism 4, which works together to support and fix the glass.

[0038] Furthermore, in the above technical solution, the tail end of the pressure plate 5 is fixedly connected to the bottom front end of the machine head 2 through a connector. The middle position of the pressure plate 5 is a circular hollow structure. The front end of the pressure plate 5 is provided with a water outlet 51. Above the front end of the pressure plate 5, and connected to one end of the water outlet 51, is a water inlet connector 52. The water inlet connector 52 is connected to a water supply device through a conduit.

[0039] Furthermore, in the above technical solution, a waterproof cover 54 is installed on the top of the pressure plate 5, and multiple protrusions 55 are fixedly installed on the bottom of the waterproof cover 54. The multiple protrusions 55 are adapted to and connected with the corresponding slots on the upper surface of the pressure plate 5. The middle position of the waterproof cover 54 is a hollow structure, and the waterproof cover 54 is sleeved on the outside of the drill bit.

[0040] In this example, the pressure plate 5 is fitted onto the outside of the drill bit below the drill head 2. The center of the pressure plate 5 has a circular hollow structure, facilitating the drill bit's passage for drilling operations. The water inlet connector 52 is connected to an external water supply device via a conduit, enabling direct delivery of cooling water during the drilling process, avoiding the use of existing spray nozzles to spray cooling water. This improves cooling efficiency and reduces water waste. A waterproof cover 54 is installed on top of the pressure plate 5. This cover effectively prevents the sprayed cooling water from splashing everywhere during the high-speed rotation of the drill bit, protecting operators and equipment.

[0041] Furthermore, in the above technical solution, an annular sealing ring 53 is fixedly installed at the lower part of the hollow position in the middle of the pressure plate 5. The sealing ring 53, the waterproof cover 54 and the middle position of the pressure plate 5 do not come into contact with the drill bit. The sealing ring 53 further enhances the sealing performance of the bottom of the pressure plate 5 and prevents cooling water from leaking from the gap between the pressure plate 5 and the upper surface of the glass.

[0042] The drilling device for processing acrylic glass provided by this utility model operates as follows:

[0043] The acrylic sheet to be processed is moved onto the table 3. The cylinder 44 is activated, causing its output end to move forward, which in turn moves the wedge block 45 closer to the roller 43. At this time, the support base 41 rises, and the ball bearings 42 on the upper surface of the support base 41 contact the acrylic sheet. Then, according to the location where a hole needs to be drilled, the operator pushes the glass, moving the drilling point directly below the drill bit. The cylinder 44 is then activated again, causing its output end to retract, which in turn moves the wedge block 45 away from the roller 43. The support base 41 descends under its own weight, and the glass slowly falls onto the upper surface of the table 3.

[0044] Subsequently, the machine head 2 drives the pressure plate 5 and the drill bit to descend. When the bottom of the pressure plate 5 presses against the upper surface of the glass, the external water supply device is turned on. Cooling water flows into the front end of the pressure plate 5 through the water inlet connector 52 and then flows out from the water outlet 51, directly cooling and lubricating the drill bit and the drilling part.

[0045] Start the drill head 2 to make the drill bit rotate at high speed and begin drilling holes in the acrylic sheet. During the drilling process, the waterproof cover 54 works in conjunction with the pressure plate 5 to effectively prevent cooling water from splashing everywhere under the high-speed rotation of the drill bit, protecting the operator and equipment. The debris and coolant generated during the drilling process will fall into the guide groove 31 on the upper surface of the table 3. As the debris and coolant in the guide groove 31 increase, they will be discharged from the device through the drain outlets at both ends and the drain pipe 32, keeping the working environment clean and preventing debris and coolant from affecting the glass processing.

[0046] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
