Description

Technical Field

[0001] This invention relates to clay model milling, specifically to a movable clay model milling machine and its moving method. Background Technology

[0002] Clay models are traditional car body models sculpted from clay in automotive design. They are primarily used to express the realistic effect of a car's shape. Currently, clay models are mainly designed using computer-aided design, followed by shaping using a three-axis milling machine. To facilitate processing, the clay is a mixture of grease, fillers, modifiers, and pigments. This makes it easy to work with, minimizes wear on milling equipment, allows for easy modification, and prevents weathering, drying, or cracking after processing. It also exhibits good dimensional stability.

[0003] For machining production lines, the design process may require multiple alternative clay models. Therefore, it's necessary to process multiple clay models in a short period for review by designers and decision-makers. In actual machining, the clay models should ideally not be moved. Often, a single clay model machining point requires a milling machine. For machining multiple clay models, the processing cost is high, and it also reduces the available space on the production line. Therefore, optimizing the structure of the milling machine and improving space utilization is a worthwhile research topic. Summary of the Invention

[0004] The purpose of this invention is to provide a portable clay model milling machine and a method for moving it, so as to improve the problem that when processing multiple clay models, each clay model needs to use a milling machine, which leads to an increased demand for milling machines, an increased space occupation, and an increase in production costs.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A portable clay model milling machine includes a base, an electromagnet, and a ejection mechanism. The base is located at the lower end of the main body and supports the main body. The electromagnet is installed at the lower end of the base and is used to attract and lock a pre-embedded steel plate at the workstation. The ejection mechanism is installed at the lower end of the base and is used to raise the base so that a transport trolley can lift it. The purpose is to facilitate the insertion and removal of the transport trolley by using the base to support the main body, the transport trolley to move the main body, the electromagnet for stable installation, and the ejection mechanism to adjust the height difference between the base and the ground.

[0007] Preferably, the aforementioned launching mechanism is a synchronous hydraulic jack. The base has a first mounting hole for mounting the synchronous hydraulic jack. The bottom of the synchronous hydraulic jack has a flange, which is fixed in the first mounting hole. The synchronous hydraulic jack is used to hang upside down in the first mounting hole. The purpose is to improve the lifting stability of the base using the synchronous hydraulic jack and prevent the body from tilting.

[0008] A further technical solution involves using two or more synchronous hydraulic jacks. These jacks are connected to an electric pump station, which drives them to work synchronously. The purpose is to achieve multi-point support for the main body through multiple synchronous hydraulic jacks, thereby ensuring the uniformity of load transfer and preventing excessive load on a single jack.

[0009] Preferably, a lifting mechanism is installed on the aforementioned transport trolley, which is used to abut the lower end of the base. The purpose is to ensure that the load of the main body is transferred to the transport trolley by having the lifting mechanism on the transport trolley contact the base, so as to facilitate the retraction of the push-out mechanism.

[0010] Preferably, there are two or more electromagnets, and the base is provided with a second mounting hole corresponding to the electromagnet. The upper end of the electromagnet is fixed in the second mounting hole, and the lower end of the electromagnet is at the same horizontal height as the lower surface of the base.

[0011] Preferably, the above-mentioned body includes a five-axis cutting machine, and the upper end of the base is provided with a guide rail, on which the five-axis cutting machine is mounted.

[0012] This invention also discloses a method for moving a milling machine. Using the aforementioned clay model milling machine, the ejection mechanism is adjusted to a released state, lifting the base; a sufficient installation gap is formed between the base and the pre-embedded steel plate; a transport trolley is placed into the installation gap; then the ejection mechanism is retracted, placing the main body on the transport trolley; the transport trolley moves the main body, completing the transport. During main body installation, the transport trolley moves the main body to the pre-embedded steel plate at the workstation; the ejection mechanism is again adjusted to a released state, detaching the base from the transport trolley; then the transport trolley is moved away; the ejection mechanism is slowly retracted until the base contacts the pre-embedded steel plate at the workstation; at this point, the electromagnet is activated, attracting the electromagnet to the pre-embedded steel plate, completing the anchoring.

[0013] Preferably, the aforementioned launching mechanism is a synchronous hydraulic jack. When releasing or retracting the synchronous hydraulic jack, it should be checked whether the synchronous hydraulic jack is connected to an electric pump station, so that the synchronous hydraulic jack can work synchronously through the electric pump station.

[0014] Preferably, the aforementioned body is placed on a transport trolley, and the transport trolley moves the body and adjusts the relative position of the base and the pre-embedded steel plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are at least one of the following:

[0016] This invention utilizes a base for support and a push-out mechanism mounted on the bottom of the base to elevate the main body to a certain extent. A transport trolley facilitates movement, and after movement, electromagnets mounted on the bottom of the base provide fixation. The method of movement depends on processing requirements. When the clay model remains stationary, a small number of milling machines can be used to process more clay models, significantly reducing equipment procurement costs. Furthermore, after the clay models are recycled, the equipment can be promptly transferred, reserving sufficient processing space for the production line. A guide rail is mounted on the base, and a five-axis cutting machine on the guide rail performs three-dimensional cutting after the base is fixed. Multiple synchronous hydraulic jacks are used for synchronized lifting and lowering, ensuring the base remains level during lifting and preventing the main body from tilting. A lifting mechanism transfers the load, ensuring the main body remains horizontal during load transfer and effectively preventing tipping during transfer. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] Example 1:

[0027] refer to Figures 1 to 3 As shown, one embodiment of the present invention is a movable clay model milling machine comprising: a base 2, an electromagnet 3, and a push-out mechanism 4. The base 2 is located at the lower end of the body 1 and serves to support the body 1. The electromagnet 3 is installed at the lower end of the base 2 and is used to attract and lock the pre-embedded steel plate G at the workstation. The push-out mechanism 4 is installed at the lower end of the base 2 and is used to raise the base 2 so that a transport trolley 5 can lift the base 2.

[0028] Among them, the base 2 serves as a platform for mineral castings, mainly used to place the main body 1 and provide good support when the main body 1 is working.

[0029] The base 2 is typically rectangular, and its length needs to be slightly greater than the movement length of the main body 1 along the X-axis. This is to ensure that the base 2 can meet the movement distance requirements of the main body 1 under external conditions when constructing the X-axis. For example, based on the dimensions of existing vehicle clay models, the length of the base 2 is usually greater than or equal to 3000 mm.

[0030] An electromagnet 3 is installed at the lower end of the base 2. The embedded steel plate G at the workstation is a pre-installed anchoring steel plate on the ground. The electromagnet 3 is a DC suction cup type electromagnet that attracts the embedded steel plate G. The DC suction cup electromagnet is positioned in the reserved space at the lower end of the base 2. When the base 2 needs to be positioned at the workstation, the electromagnet 3 is energized, causing it to attract the embedded steel plate G, thus making the base 2 firmly attached to the ground at the workstation and securing it. The base 2 needs to have pre-installed electrical wiring for the electromagnet 3 to enable locking and releasing of the base 2.

[0031] With the base 2 locked in place by an electromagnet 3, the base 2 is easily released into a movable state. Therefore, by pushing the two ends of the mechanism 4 against the ground and the base 2 respectively, a height difference is created between the base 2 and the ground. The height difference needs to be greater than the working height of the transport trolley 5. Thus, when a height difference is created between the base 2 and the ground, the transport trolley 5 can move to the lower end of the base 2. Then, the push mechanism 4 is used to retract the base 2 to reduce the height difference, so that the base 2 completely contacts the transport trolley 5. During the retraction process, the push mechanism 4 gradually lifts the base 2 off the ground. Subsequently, the base 2 is completely supported by the transport trolley 5. The transport trolley 5 is used to move the base 2 and the main body 1 on the base 2 to other workstations to complete the transport.

[0032] It is worth noting that the main body 1 uses a lightweight milling machine developed by Aipei Measurement Equipment Co., Ltd. With sufficient lightweight, the center of gravity of the main body 1 is adjusted to the initial position, and the center of gravity of the lightweight milling machine is applied to the column of the main body 1, so that it can be easily lifted by the transport trolley 5.

[0033] The Body 1 system features a fully enclosed dustproof structure, making it suitable for harsh model processing environments. During the cutting process of clay models using Body 1, large chunks of clay are typically cut off and fall onto the workstation. If the workstation itself is not contaminated, the cut clay can be recycled and reused, thus reducing material waste.

[0034] Clay models, as a design medium, are frequently used to directly represent the shape of products. Because clay is easy to process and recycle, it facilitates designers' expression of product ideas and makes product modifications easier. Clay models also serve as a bridge between two-dimensional and three-dimensional forms, aiding in styling design and helping to demonstrate the feasibility of the shape. Once the model's shape is approved, it can be measured using a coordinate measuring machine to obtain surface dimensional parameters, providing sufficient data support for drawing product outlines. It is worth noting that existing clay softens when heated, and it cannot function effectively without softening. Therefore, before milling, the clay model needs to be softened in an oven and transported to the workstation using a pallet. Before processing, the unformed clay model is easy to move, allowing for rapid assembly of the milling machine and clay model, enabling the creation of clay model processing spaces in multiple areas of the production line. At the same time, once the clay model is constructed, both the main body 1 and the clay model can be moved away to avoid occupying the limited space of the production line.

[0035] Example 2:

[0036] Based on the above embodiments, refer to Figure 2 and Figure 3 As shown, in another embodiment of the present invention, the aforementioned ejection mechanism 4 is a synchronous hydraulic jack, the aforementioned base 2 is provided with a first mounting hole 6, the aforementioned first mounting hole 6 is used to install the synchronous hydraulic jack, the aforementioned synchronous hydraulic jack is provided with a flange 601 at the bottom, the aforementioned flange 601 is fixed in the first mounting hole 6, and the aforementioned synchronous hydraulic jack is used to hang upside down in the first mounting hole 6.

[0037] Among them, the launching mechanism 4 adopts a synchronous hydraulic jack, which is an existing split hydraulic jack. The synchronous hydraulic jacks have the same specifications and are located at multiple positions on the base 2. The synchronous hydraulic jacks temporarily serve as support units for the base 2 during the transfer process.

[0038] The first mounting hole 6 is a mounting hole opened at the lower end of the base 2. The synchronous hydraulic jack is installed in the first mounting hole 6 in an inverted manner, that is, the piston part of the synchronous hydraulic jack is set facing the ground. The support part of the synchronous hydraulic jack is welded with flange 601 and fixed in the first mounting hole 6 through flange 601, so that the synchronous hydraulic jack is perpendicular to the base 2.

[0039] It is worth noting that, in order to facilitate the replacement of the synchronous hydraulic jack, the piston diameter of the synchronous hydraulic jack is smaller than the diameter of flange 601, and the diameter of the first mounting hole 6 is greater than or equal to the diameter of flange 601.

[0040] Furthermore, there are two or more synchronous hydraulic jacks, which are used to connect to an electric pump station, and the electric pump station drives the synchronous hydraulic jacks to work synchronously.

[0041] The synchronous hydraulic jacks have their inlet and outlet ports connected to an electric pump station. A pre-installed oil pump pipeline channel is provided on the base 2, allowing the oil pipes of the synchronous hydraulic jacks to extend from the base 2 and connect to the electric pump station. The electric pump station synchronously drives two or more synchronous hydraulic jacks, ensuring that the piston extension distance of the synchronous hydraulic jacks remains consistent. This avoids the risk of tilting the base 2 during lifting and lowering, and ensures that the main body 1 will not tip over during lifting or lowering.

[0042] Example 3:

[0043] Based on the above embodiments, refer to Figure 1 and Figure 5 As shown, in another embodiment of the present invention, a lifting mechanism 501 is installed on the aforementioned transport trolley 5, and the lifting mechanism 501 is used to abut the lower end of the base 2.

[0044] The lifting mechanism 501 is an existing jack. The upper end of the lifting mechanism 501 contacts the lower end of the base 2. The lifting mechanism 501 is set in a plane. The plane of the lifting mechanism 501 has a certain area, so as to ensure that when the lifting mechanism 501 contacts the base 2, the load of the base 2 can be evenly applied to the transport trolley 5.

[0045] The transport trolley 5 is equipped with a handle and pulleys. The handle facilitates the application of pulling force to the transport trolley 5, and the pulleys help to reduce the coefficient of friction between the transport trolley 5 and the ground. Thus, during the placement of the main body 1, it is easy to adjust the corresponding position of the base 1 and the pre-embedded steel plate G through the transport trolley 5.

[0046] Example 4:

[0047] Based on the above embodiments, refer to Figure 1 and Figure 4As shown, in another embodiment of the present invention, there are two or more electromagnets 3, and the base 2 is provided with a second mounting hole 7 corresponding to the electromagnet 3. The upper end of the electromagnet 3 is fixed in the second mounting hole 7, and the lower end of the electromagnet 3 is at the same horizontal height as the lower surface of the base 2.

[0048] The electromagnet 3 can be fixed in the second mounting hole 7 using existing fasteners. The electromagnet 3 is equipped with mounting bolts, and the second mounting hole 7 has bolt holes. The mounting bolts are inserted into the bolt holes of the second mounting hole 7, thus securing the electromagnet 3 in the second mounting hole 7. The dimensions of the electromagnet 3 correspond to those of the second mounting hole 7, preventing the electromagnet 3 from shaking within the second mounting hole 7. A through hole can be provided on the side wall of the second mounting hole 7 for the guide wire of the electromagnet 3. The electromagnet 3 is connected to the electrical control system via its guide wire, energizing it. The resulting magnetic attraction causes the electromagnet 3 to adhere to the embedded steel plate, thus fixing the base 2.

[0049] Example 5:

[0050] Based on the above embodiments, refer to Figure 6 As shown, in another embodiment of the present invention, the body 1 includes a five-axis cutting machine 8, the upper end of the base 2 is provided with a guide rail 201, and the five-axis cutting machine 8 is mounted on the guide rail 201.

[0051] The five-axis cutting machine 8 is equipped with a slider H, which forms a linear guide rail with the guide rail 201, so that the body 1 moves linearly on the guide rail 201. When the base 2 is fixed, the body 1 can move linearly along the guide rail 201 under the action of the slider H.

[0052] Among them, the five-axis cutting machine 8 adopts a lightweight milling machine. The main body of the five-axis cutting machine 8 adopts a high-rigidity frame structure, and the columns and cross arms adopt small cross-sectional areas to meet the lightweight requirements of the body 1, thereby satisfying the mobility of the five-axis cutting machine 8 on the guide rail 201.

[0053] Specifically, the five-axis cutting machine 8 moves along the X-axis on the guide rail 201. The column of the five-axis cutting machine 8 is equipped with a Z-axis rail, and a slide plate is provided on the Z-axis rail. The slide plate moves along the Z-axis. A horizontal arm is provided on the slide plate, and the horizontal arm moves along the Y-axis. A milling head is provided at the head of the horizontal arm. The milling head includes an AB rotating arm and a milling cutter. The milling cutter is mounted on the AB rotating arm, and the AB rotating arm drives the milling cutter to rotate on the A-axis and B-axis. Thus, the milling cutter realizes the rotation of the X-axis, Y-axis, Z-axis, and A-axis and B-axis.

[0054] Specifically, the milling head is mounted on the end of the horizontal arm of the five-axis cutting machine 8. The milling head is a special cutting head for processing foam, clay, and wood substitutes.

[0055] The AB rotary arm consists of a motorized A-axis, a motorized B-axis, and an electric spindle. Its milling cutter comprises a standard tool holder and a special-purpose tool. The standard tool holder is inserted into the AB rotary arm, and the electric spindle drives the milling cutter to rotate. The motorized A-axis and B-axis respectively tilt the milling cutter laterally and longitudinally, thus obtaining various feed angles. The repeatability error between the electric spindle and the standard tool holder is less than 0.01 mm, allowing the desired machining angle to be reused directly after a single tool setting, greatly improving efficiency.

[0056] It is worth noting that the five-axis cutting machine 8 is an electrified device. The rotation of the A and B axes can be automatically controlled by programming or direct command code, so that different machining angles can be arbitrarily selected within the range; the speed of the electric spindle can be conveniently controlled on the software interface.

[0057] Example 6:

[0058] This embodiment discloses a method for moving a milling machine. Using the clay model milling machine of the above embodiment, the ejection mechanism 4 is adjusted to the release state, and the ejection mechanism 4 lifts the base 2; a sufficient installation gap is formed between the base 2 and the pre-embedded steel plate, the transport trolley 5 is placed in the installation gap, and then the ejection mechanism 4 is retracted, so that the body 1 is placed on the transport trolley 5; the transport trolley 5 drives the body 1 to move, and the transport is completed.

[0059] During installation, the main body 1 is moved to the pre-embedded steel plate at the work station by the transport trolley 5. The push-out mechanism 4 is then adjusted to release, so that the base 2 is detached from the transport trolley 5. The transport trolley 5 is then moved away, and the push-out mechanism 4 is slowly retracted until the base 2 contacts the pre-embedded steel plate at the work station. At this time, the electromagnet 3 is turned on, so that the electromagnet is attracted to the pre-embedded steel plate, thus completing the anchoring.

[0060] Specifically, when the main body 1 needs to be moved, the synchronous hydraulic jack of the ejection mechanism 4 lifts the base 2 and the main body 1, while simultaneously moving the transport trolley 5 to the lower end of the base 2. The ejection mechanism 4 is then slowly released again until the base 2 touches the upper end of the transport trolley 5, and until the piston of the ejection mechanism 4 is removed from the ground. At this point, the base 2 and the main body 1 on the transport trolley 5 are in a movable state. The transport trolley 5 then moves the base 2 and the main body 1 to the designated position, completing the transport process.

[0061] After the transport trolley 5 moves the base 2 to the designated position, the position of the base 2 is adjusted by the transport trolley 5 so that the track 501 on the base 2 corresponds to the X-axis to be processed. At this time, the ejection mechanism 4 is released again, so that the piston of the ejection mechanism 4 contacts the ground. As the piston of the ejection mechanism 4 extends, the base 2 is separated from the upper end of the transport trolley 5. At this time, the position of the base 2 is checked again. After confirming that the base 2 has not changed in the designated position, the transport trolley 5 is removed, and the piston of the ejection mechanism 4 is retracted so that the base 2 contacts the embedded steel plate G on the ground. Then the DC electromagnet 3 is turned on, so that the electromagnet 3 is attracted to the embedded steel plate, thereby fixing the base 2 in the work position. At the same time, the main body 1 on the guide rail 201 can start working.

[0062] It is worth noting that clay, after being contaminated and re-recycled and softened, can be reused for sculpting like new clay. However, after repeated use, the properties of clay may change, such as the formation of air bubbles leading to a decrease in density and viscosity, which may affect the quality of the mold. Therefore, before moving the body 1, it is necessary to ensure that the clay at the workstation is in a stable and machinable state. After the body 1 is moved to the workstation by the transport trolley 5 and the tool is set, it can be cut according to the predetermined program to achieve the processing of the clay mold.

[0063] Furthermore, in order to ensure that there is no uneven local load distribution during the installation of the launching mechanism 4, the launching mechanism 4 is a synchronous hydraulic jack. When the synchronous hydraulic jack is released or retracted, it should be checked whether the synchronous hydraulic jack is connected to the electric pump station, so that the synchronous hydraulic jack can work synchronously through the electric pump station.

[0064] When the base 2 is located on the transport trolley 5, during the release process of the ejection mechanism 4, it is necessary to first check whether the synchronous hydraulic jack is connected to the electric pump station. After confirming that the oil inlet and outlet of the synchronous hydraulic jack are connected to the electric pump station, the piston of the ejection mechanism 4 is released synchronously. Before the piston of the ejection mechanism 4 touches the ground, the measuring tool is used to measure the length of the piston extending into the ejection mechanism 4 to ensure that the piston extension length of each ejection mechanism 4 is consistent. If the length is inconsistent, the equipment installation should be stopped, and the ejection mechanism 4 needs to be repaired or replaced.

[0065] When the ejection mechanism 4 lifts the base 2 from the ground, it needs to be lifted slowly. During the lifting process, a level can be placed on the base 2. When the level clearly indicates that the base 2 is tilted, the ejection mechanism 4 should be stopped, and the base 2 should be lifted by hoisting to facilitate the maintenance or replacement of the ejection mechanism 4.

[0066] Furthermore, the aforementioned main body 1 is on the transport trolley 5, and the transport trolley 5 moves the main body 1 and adjusts the relative position of the base 2 and the pre-embedded steel plate.

[0067] It is worth noting that its five-axis cutting machine 8 can be adapted to an electronic tool setter. Specifically, the milling cutter is replaced with a TS27R electronic tool setter from the British company RENISHAW. After the base 2 is installed, the electronic tool setter is used for tool setting and to unify the workpiece coordinate system and machine coordinate system. This allows the five-axis cutting machine 8 to quickly measure the three coordinates on the connected computer. The obtained coordinate system can be corrected by the computer for the tool length and diameter offset values. The position of the base 2 moved by its trolley 5 has a very high tolerance for error, so the installation requirements of the base 2 can be met by visual positioning alone.
