Description

Technical Field

[0001] This utility model relates to the field of CNC machining, and in particular to a fixture structure. Background Technology

[0002] In modern manufacturing, CNC machining technology, with its advantages of high precision and high efficiency, is widely used in the processing and production of various product parts. Currently, three-axis CNC machining centers are the most commonly used equipment for processing many product parts.

[0003] In actual machining processes, for general product parts, three-axis CNC machining centers primarily use a modular machining fixture approach to progressively complete the machining of various precision components. This method effectively meets machining requirements for parts with relatively simple structures. However, with the continuous development of the manufacturing industry, product structures are becoming increasingly complex and diverse. For machining complex structural parts, the traditional modular machining fixture approach has revealed many drawbacks. These complex structural parts often have multiple reference points, numerous relative positional dimensions, and small tolerances.

[0004] Existing fixture structures have too many machining clamping positions, and the method of splitting the machining clamping positions to process product parts is inefficient. Utility Model Content

[0005] To address the aforementioned problems, this utility model is implemented through the following technical solution.

[0006] A fixture structure includes: a connecting seat; two mold cores mounted on the connecting seat; two clamping grooves formed on the mold cores for clamping products; and two deformation grooves formed on the bottom wall of the clamping grooves for providing space for the elastic deformation of the mold cores to assist the clamping grooves in clamping the products.

[0007] Preferably, the mold core includes: a positioning bolt, which is installed in the connecting seat and passes through two deformation grooves.

[0008] Preferably, the mold core further includes: a through hole, formed between the two deformation grooves, through which the positioning bolt passes; and a threaded groove, formed on one inner wall of the deformation groove, with one end of the positioning bolt threadedly connected to the threaded groove.

[0009] Preferably, the mold core further includes two clamping heads, which are respectively installed on the inner walls of the two sides of the clamping groove.

[0010] Preferably, the connecting seat includes: a base plate, mounted on one side of the connecting seat; and a mounting seat, mounted on the base plate, with the mold core mounted on the mounting seat.

[0011] Preferably, the base plate includes: two mounting slots, which are formed on the top of the mounting base, and the mold core is installed in the mounting slots; and two fixing bolts, which are installed on the mounting base and penetrate the mold core.

[0012] Preferably, it further includes: a machine tool; a rotating base mounted on the machine tool, and the connecting seat mounted on the rotating base.

[0013] Preferably, the connecting seat includes a reinforcing rib installed at the bottom of the base plate, and the reinforcing rib is connected to one side of the connecting seat.

[0014] This utility model provides a fixture structure. Compared with the prior art, it has the following advantages: by opening several clamping slots on the mold core, multiple products can be clamped and processed simultaneously, reducing the time for clamping and disassembling products, increasing the number of products processed per unit time, and thus significantly improving the overall processing efficiency; this fixture structure adopts an integrated design concept, and achieves stable clamping of products through the elastic deformation of the mold core, avoiding the cumbersome process of using many processing clamps and frequently disassembling processing clamps in traditional fixtures, making the processing process smoother and more efficient.

[0024] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0025] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0026] Reference Figures 1-5 A fixture structure includes: a connecting seat 200; two mold cores 300 mounted on the connecting seat 200; two clamping grooves 301 formed on each mold core 300 for clamping a product; and two deformation grooves 302 formed on the bottom wall of each clamping groove 301 for providing space for the elastic deformation of the mold core 300 to assist the clamping grooves 301 in clamping the product.

[0027] In this embodiment, by creating several clamping slots 301 on the mold core 300, multiple products can be clamped and processed simultaneously. The clamping slots 301 on the mold core 300 can clamp and fix the products through the deformation of the mold core 300. The deformation slots 302 provide space for the elastic deformation of the mold core 300 to assist the clamping slots 301 in clamping the products. When a product is placed in the clamping slot 301, since the size and shape of the product may have certain tolerances, the mold core 300 can generate a certain amount of elastic deformation through the deformation slots 302, allowing the clamping head 303 to better fit the product surface and achieve tight clamping of the product. At the same time, this elastic deformation can also buffer the vibration and impact forces generated during processing to a certain extent, protecting the product and fixture from damage.

[0028] The mold core 300 includes: a positioning bolt 304 installed in the connecting seat 200, the positioning bolt 304 passing through two deformation grooves 302; a through hole 305 formed between the two deformation grooves 302, the positioning bolt 304 passing through the through hole 305; a threaded groove 306 formed on one side inner wall of the deformation groove 302, one end of the positioning bolt 304 being threadedly connected to the threaded groove 306; and two clamping heads 303, the two clamping heads 303 being respectively installed on the two sides inner walls of the clamping groove 301.

[0029] The aforementioned positioning bolt 304 is used to control the degree of deformation of the mold core 300 and the distance between the two clamping heads 303 in the clamping groove 301.

[0030] The connecting seat 200 includes: a base plate 201, mounted on one side of the connecting seat 200; and a mounting seat 203, mounted on the base plate 201, with the mold core 300 mounted on the mounting seat 203. The base plate 201 includes: two mounting grooves 204, each located on the top of the mounting seat 203, with the mold core 300 mounted within the mounting grooves 204; and two fixing bolts 205, mounted on the mounting seat 203 and penetrating the mold core 300.

[0031] The aforementioned connecting seat 200 is the basic support component of the entire fixture structure, and the base plate 201 is installed on one side of the connecting seat 200. The base plate 201 serves to further stabilize the connecting seat 200 and facilitate its installation with other components. A reinforcing rib 202 is installed at the bottom of the base plate 201, and the reinforcing rib 202 is connected to one side of the connecting seat 200. The reinforcing rib 202 enhances the structural strength between the base plate 201 and the connecting seat 200, improves the stability of the entire connecting seat 200, and prevents deformation due to stress during processing, thereby ensuring the fixture's clamping accuracy for the product. The mounting groove 204 provides a precise installation position for the mold core 300, ensuring the accuracy of the mold core 300's installation. Two fixing bolts 205 are used to firmly fix the mold core 300 to the mounting seat 203. The fixing bolt 205 is installed on the mounting base 203 and passes through the mold core 300. By tightening the fixing bolt 205, the mold core 300 is tightly connected to the mounting base 203, preventing the mold core 300 from shifting during processing and ensuring the stability of product clamping.

[0032] Machine tool 100; rotating base 101, mounted on the machine tool 100, connecting seat 200 mounted on the rotating base 101; the connecting seat 200 includes: reinforcing rib 202, mounted on the bottom of the base plate 201, the reinforcing rib 202 being connected to one side of the connecting seat 200.

[0033] During use, the positioning bolt 304 is installed inside the connecting seat 200, so that the positioning bolt 304 passes through the two deformation grooves 302 and the through hole 305 between the two deformation grooves 302 in sequence. Finally, one end of the positioning bolt 304 is threadedly connected to the threaded groove 306 on the inner wall of one side of the deformation groove 302. The positioning bolt 304 not only serves to fix the mold core 300, but also controls the degree of deformation of the mold core 300 and the distance between the two clamping heads 303 in the clamping groove 301. During installation, it is necessary to ensure that the positioning bolt 304 is tightened appropriately to ensure that the mold core 300 can deform normally and achieve effective clamping of the product. The product to be processed is placed into the clamping groove 301 on the mold core 300. Because the size and shape of the product may have certain tolerances, when the product is placed into the clamping groove 301, the mold core 300 will undergo a certain elastic deformation through the deformation groove 302. The elastic deformation of the mold core 300 allows the two clamping heads 303 installed on the inner walls of both sides of the clamping groove 301 to better conform to the product surface, thereby achieving tight clamping of the product. This elastic clamping method can not only adapt to the dimensional tolerances of the product, but also buffer the vibration and impact generated during processing to a certain extent, protecting the product and the fixture from damage.

[0034] According to the processing requirements of the product, the angle of the connecting seat 200 is adjusted by rotating the base 101 to place the product in a suitable processing position. The flexible rotation function of the rotating base 101 can meet the angle requirements of different products and different processing parts, improving the flexibility and efficiency of processing. After the product is adjusted to the appropriate processing position, the machine tool 100 is started for CNC machining. During the processing, the fixture structure can stably hold the product, ensuring the processing accuracy and dimensional stability of each part of the product, and reducing errors caused by human factors and processing vibration. After processing, the positioning bolts 304 are loosened to allow the elastic deformation of the mold core 300 to recover, thereby allowing the clamping head 303 to release its grip on the product, and the processed product is taken out from the clamping slot 301, completing the entire processing process.

[0035] In summary, compared with existing technologies, it has the following beneficial effects:

[0036] By opening several clamping slots 301 on the mold core 300, multiple products can be clamped and processed simultaneously, reducing the time for clamping and disassembling products, increasing the number of products processed per unit time, and thus significantly improving the overall processing efficiency.

[0037] This fixture adopts an integrated design concept, and achieves stable clamping of the product through the elastic deformation of the mold core 300. This avoids the cumbersome process of using many machining clamps and frequently disassembling machining clamps, which is common in traditional fixtures, making the machining process smoother and more efficient.
