Description

Technical Field

[0001] The present invention relates to the technical field of mechanical manufacturing, and specifically to a mineral casting bed structure and a preparation method applied to a dicing machine. Background Technique

[0002] As the core basic component of a dicing machine, the dynamic and static performance of the bed structure directly affects the processing accuracy of the dicing machine and the quality of the diced products. The comprehensive performance of a high-precision dicing machine can be improved by optimizing the bed structure or materials. At present, the structural design and control system of high-precision dicing machines are gradually mature and perfect, but there are still deficiencies in material performance. Excellent materials are one of the solutions to improve the bed performance.

[0003] At present, the most widely used gantry bed structure in the market adopts cast iron. A crossbeam, two columns, and a base are connected by studs. Due to the residual stress, processing defects, poor long-term stability in the cast iron processing process, and serious pollution in the production process, it needs to be cast at high temperature, and the preparation cycle is too long. The damping vibration performance gradually fails to meet the requirements, which does not conform to the current concept of green manufacturing. Another type of bed made of artificial marble has a certain improvement in its dynamic characteristics, but the time and economic costs of this material are relatively high, the machinability is poor, and the impact resistance is poor. Therefore, we design a mineral casting bed structure and a preparation method applied to a dicing machine to solve the above technical problems. Summary of the Invention

[0008] As a further preferred solution of the present invention: A plurality of screw holes matching with the cross screws B are equidistantly opened on the top surface of the marble bed along the direction of the X-axis guide rail. The cross screw B is sleeved with a second pressing plate. The outer side surface of the second pressing plate abuts against the side surface of the X-axis guide rail.

[0009] The second aspect provides a preparation method for a mineral casting bed structure applied to a dicing machine, including the following steps:

[0010] S1.

The bed body material is a composite material formed by using natural ore crushed into aggregate particles and adding components such as epoxy resin. Compared with natural marble, the cost is greatly reduced. In the components of mineral castings, most of the aggregate system and fillers are recycled and reused industrial wastes. Compared with cast iron bed bodies, the environmental pollution is small. The whole production process of mineral castings is at room temperature, there is no waste gas emission, the mold can be reused repeatedly, and the resource utilization rate is high, which conforms to the concept of green manufacturing and no pollution. This device overcomes the disadvantages of traditional cast iron bed bodies and natural marble bed bodies, realizes the optimization of the static and dynamic performance of the machine tool bed body, lightweight design, and improvement of the vibration damping performance; and ensures accuracy and long-term stability.

[0024] 2. Through the cooperative connection of the screw, upper connecting block, lower connecting block and nut, when the two parts are combined, the requirement of ensuring the verticality of the gantry structure is achieved, avoiding the traditional multiple bolt connections, saving time and effort in operation, and being more convenient for installation. By using a manufacturing mold, the Y-axis base and the marble bed body share one mold, directly ensuring the installation verticality requirement. This integrated mold can also enable the vibrator to better compact the mixture. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1-5, in the first aspect of the present invention, a mineral casting bed structure applied to a dicing machine is provided, which includes a Y-axis base 1 and a marble bed 11. The Y-axis base 1 is integrally formed by two struts and a cross beam. The Y-axis base 1 is vertically installed on the top of the marble bed 11. The front side surface of the cross beam is provided with a Y-axis guide rail. The Y-axis guide rail includes two Y-axis driven rails 2 and a Y-axis reference rail 5 arranged in parallel with each other. The Y-axis driven rail 2 is located above the Y-axis reference rail 5. Above the Y-axis guide rail, a plurality of cross screws A3 are provided. On the top of the marble bed 11, an X-axis guide rail is provided. The X-axis guide rail includes two X-axis driven rails 15 and an X-axis reference rail 12 arranged in parallel with each other. The X-axis driven rail 15 is located on the left side of the X-axis reference rail 12. On the outside of the X-axis guide rail, a plurality of cross screws B14 are provided. At the bottom of the strut, a clamping post 16 is provided. On the top of the marble bed 11, a clamping hole 17 corresponding to the clamping post 16 is opened. A matching connecting cushion block 10 is provided between the clamping hole 17 and the clamping post 16. On the front side of the strut, a lower connecting block 9 is provided. The lower connecting block 9 is fixedly connected to the top surface of the marble bed 11 by bolts. The lower connecting block 9 is sleeved outside the screw rod 7. On the upper part of the outer side of the screw rod 7, an upper connecting block 8 is sleeved. The rear side surface of the upper connecting block 8 contacts the front side surface of the strut. The lower connecting block 9 does not contact the strut. A plurality of nuts matching with the screw rod 7 are sleeved on the screw rod 7. The plurality of nuts respectively abut against the upper and lower surfaces of the upper connecting block 8 and the top surface of the lower connecting block 9.

[0033] On the front side surface of the cross beam, a plurality of screw holes matching with the cross screws A3 are equidistantly opened along the direction of the Y-axis guide rail. The cross screw A3 is sleeved with a first pressing plate 4 matching with it. The first pressing plate 4 is of a semi-circular structure. On the side of the head of the cross screw A3 away from the cross groove, there is an outward inclined side surface with a downward closing mouth shape. On the inner side surface of the first pressing plate 4, there is an inward inclined side surface matching with the outward inclined side surface. The bottommost outer surface of the first pressing plate 4 abuts against the top surface of the Y-axis guide rail.

[0034] On the top surface of the marble bed 11, a plurality of screw holes matching with the cross screws B14 are equidistantly opened along the direction of the X-axis guide rail. The cross screw B14 is sleeved with a second pressing plate 13. The outer side surface of the second pressing plate 13 abuts against the side surface of the X-axis guide rail. Here, the structural design of the cross screw B14, the second pressing plate 13 and the X-axis guide rail is similar to the structural design of the cross screw A3, the first pressing plate 4 and the Y-axis guide rail, and will not be repeated.

[0035] Through the combined connection action of the screw rod 7, the upper connecting block 8, the lower connecting block 9 and the nuts, when the two parts are combined, the requirement of ensuring the perpendicularity of the gantry structure is realized, avoiding the traditional multiple bolt connections, saving time and effort in operation and being more convenient for installation.

[0036] In the second aspect of the present invention, a preparation method for a mineral casting bed structure applied to a dicing machine is provided, including the following steps:

[0037] S1. Prepare raw materials and pre-treat them. a) Prepare the aggregate, clean, dry, cool it, and finally weigh it according to the components for standby. b) Prepare the filler, dry and cool it, and then weigh it according to the components for standby. c) Prepare the reinforcing fiber, first clean it with absolute ethanol, then dry and cool it, and finally weigh it according to the components for standby.

[0038] S2. Stirring operation. Put the treated aggregate, filler, and reinforcing fiber in step S1 into a blender and stir and mix them.

[0039] S3. Prepare the resin system. Weigh different types of epoxy resins according to the components, mix and stir them for standby.

[0040] S4. Add the uniformly mixed epoxy resin in step S3 into the blender in step S2 and mix and stir them together.

[0041] S5. Prepare the mold. Assemble the mold and apply a release agent.

[0042] S6. Pouring. Fix the mold on a vibrating table, input the uniformly mixed mixture in step S4 into the mold, start the vibrator, and vibrate it to make it dense.

[0043] S7. Constant temperature curing. Cure the mold in step S6 at a constant temperature, then open the mold and cool it to room temperature, and place it at room temperature for curing.

[0044] S8. Machining and inspection. Machine and inspect the primary product obtained in step S7.

[0045] S9. Finished product. If the inspection is qualified, the finished product is obtained; if not, it is prepared again.

[0046] The material of the aggregate in step S1 is natural ore, and the aggregate particles are obtained after crushing.

[0047] The aggregate particles are uniform spherical particles. The aggregate is stacked in layers, and each layer is staggered. The aggregate in the upper layer just fits into the gaps between the aggregates in this layer and corresponds to the aggregate in the lower layer. This model can effectively reduce the stacking void ratio. When this stacking state is reached, its stacking void ratio is 25.95%.

[0048] After the aggregate and the reinforcing fiber in step S1 are cleaned, they need to be subjected to coupling treatment to enhance the bonding strength and improve the performance and stability of the product.

[0049] The present invention adopts a manufacturing mold. The Y-axis base 1 and the marble bed body 11 share the same mold, which directly ensures the installation perpendicularity requirement. This integrated mold can enable the vibrator in step S6 to better compact the mixture.

[0050] The present invention relies on the room-temperature forming of mineral castings, with a very small shrinkage rate. The bed body material is a composite material formed by using crushed natural ore as aggregate particles and adding components such as epoxy resin. Compared with natural marble, the cost is greatly reduced. In the components of mineral castings, most of the aggregate system and fillers are recycled industrial waste. Compared with cast iron bed bodies, it has less environmental pollution. The whole production process of mineral castings is at room temperature, without waste gas emissions, the molds can be reused repeatedly, and the resource utilization rate is high, which conforms to the concept of green manufacturing and pollution-free. This device overcomes the disadvantages of traditional cast iron bed bodies and natural marble bed bodies, realizes the optimization of the static and dynamic performance of the machine tool bed body, lightweight design and improvement of the vibration damping performance; and ensures accuracy and long-term stability.

[0051] It should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
