[0002] As is well known, in machining processes, when processing parts and other materials, it is often necessary to clamp and fix the materials on a lathe chuck. However, with the increasing diversification of material requirements, many irregularly shaped materials have emerged on the market that need to be processed. These irregularly shaped materials are difficult to clamp on a lathe chuck. Not only is clamping time-consuming and labor-intensive, but there is also a risk of insecure clamping and loosening, leading to errors in machining positioning and inaccurate processing. Furthermore, they are prone to damaging the materials, increasing the defect rate and keeping production costs high. Even more seriously, these irregularly shaped materials may not be able to be clamped and fixed on the lathe chuck at all, making it impossible to fix the materials in place for processing.
[0003] Therefore, there is an urgent need for a new type of clamp to overcome the aforementioned problems. Utility Model Content
[0004] The purpose of this utility model embodiment is to provide a new type of clamp, which has the advantages of being able to adapt to the clamping and fixing of various irregular materials, quick and labor-saving clamping, firm clamping, ensuring processing accuracy, preventing material damage, improving processing yield and reducing production and processing costs.
[0005] To achieve the above objectives, a first aspect of this utility model provides a novel clamp, comprising: a mounting base, a plurality of first locking bolts and a plurality of second locking bolts. The mounting base has protruding first clamping protrusions and second clamping protrusions, arranged side-by-side with a gap between them. The first clamping protrusion has a first clamping positioning portion facing the second clamping protrusion, and the second clamping protrusion has a second clamping positioning portion facing the first clamping protrusion. The first clamping positioning portion and the second clamping positioning portion are arranged opposite each other, forming a clamping area between them. The first locking bolts pass through the first clamping protrusions and are threadedly connected to them, and the second locking bolts also pass through the first clamping protrusions and are threadedly connected to them. The clamping area is located between the first locking bolts and the second locking bolts.
[0006] Optionally, the first clamping protrusion has a first stepped hole corresponding to the first locking bolt, and the second clamping protrusion has a first threaded hole that is directly opposite to the first stepped hole. The first locking bolt passes through the first stepped hole and is threaded into the corresponding first threaded hole.
[0007] Optionally, the first clamping protrusion has a second stepped hole corresponding to the second locking bolt, and the second clamping protrusion has a second threaded hole that is directly opposite to the second stepped hole. The second locking bolt passes through the second stepped hole and is threaded into the corresponding second threaded hole.
[0008] Optionally, the first clamping positioning part is a first clamping positioning groove formed on the first clamping protrusion.
[0009] Optionally, an avoidance through hole is also formed on the groove wall of the first clamping positioning groove.
[0010] Optionally, the second clamping positioning part is a second clamping positioning groove formed on the second clamping protrusion, and the first clamping positioning groove is directly opposite the second clamping positioning groove.
[0011] Optionally, an avoidance groove is also formed on the groove wall of the second clamping positioning groove.
[0012] Optionally, a first clearance groove and a second clearance groove are formed at the connection between the first clamping protrusion and the mounting base. The opening of the first clearance groove faces the second clamping protrusion, the opening of the second clearance groove faces away from the opening of the first clearance groove, and the second clearance groove is parallel to the first clearance groove.
[0013] Optionally, a third clearance groove and a fourth clearance groove are formed at the connection between the second clamping protrusion and the mounting base. The opening of the third clearance groove faces the first clearance groove, and the opening of the fourth clearance groove faces away from the opening of the third clearance groove. Both the third clearance groove and the fourth clearance groove are parallel to the first clearance groove.
[0014] Optionally, the ends of the first clamping protrusion and the second clamping protrusion away from the mounting base are each provided with a plurality of positioning protrusions.
[0015] The mounting base of the novel clamp of this utility model has a first clamping protrusion and a second clamping protrusion protruding therefrom. The first clamping protrusion and the second clamping protrusion are arranged side by side with a gap. A first clamping positioning part is formed on the first clamping protrusion facing the second clamping protrusion, and a second clamping positioning part is formed on the second clamping protrusion facing the first clamping protrusion. The first clamping positioning part and the second clamping positioning part are arranged opposite to each other, and a clamping area is formed between the first clamping positioning part and the second clamping positioning part. A first locking bolt passes through the first clamping protrusion and is threaded to the first clamping protrusion, and a second locking bolt passes through the first clamping protrusion and is threaded to the first clamping protrusion. The clamping area is located between the first locking bolt and the second locking bolt. Then, simply place the material to be processed in the clamping area, then thread the first locking bolt through the first clamping protrusion and connect it to the first clamping protrusion, and thread the second locking bolt through the first clamping protrusion and connect it to the first clamping protrusion, until the material is clamped and fixed between the first clamping positioning part and the second clamping positioning part. Then, fix the mounting base on the lathe chuck, and the material can be processed. After the material is processed, loosen the first locking bolt and the second locking bolt, and the processed material can be taken out from the clamping area. The first clamping positioning part and the second clamping positioning part can be designed to match the shape of the material to be clamped and fixed, so as to realize the clamping and fixing of various irregular materials. This new type of fixture can more easily clamp the material on the lathe chuck, which is not only quick and labor-saving, but also more secure and reliable, preventing the risk of loosening, avoiding errors in processing positioning, and ensuring processing accuracy. Furthermore, it prevents material damage by clamping, ensuring the integrity of the material's appearance and improving the yield of material processing, thereby reducing production and processing costs. It can ensure that various irregularly shaped materials can be clamped and fixed on the lathe chuck, guaranteeing proper material handling and processing. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments, but the implementation of the present invention is not limited thereto.
[0021] Please see Figures 1 to 4 The novel clamp 100 of this utility model includes: a mounting base 10, a plurality of first locking bolts 20 and a plurality of second locking bolts 30. A first clamping protrusion 11 and a second clamping protrusion 12 protrude from the mounting base 10. The first clamping protrusion 11 and the second clamping protrusion 12 are arranged side-by-side with a gap. A first clamping positioning portion (not shown in the figure) is formed on the first clamping protrusion 11 facing the second clamping protrusion 12, and a first clamping positioning portion (not shown in the figure) is formed on the second clamping protrusion 12 facing the first clamping protrusion. The second clamping and positioning part (not shown in the figure) of 11 is arranged opposite to the first clamping and positioning part, forming a clamping area (not shown in the figure) between them. The first locking bolt 20 passes through the first clamping protrusion 11 and is threaded to the first clamping protrusion 11, and the second locking bolt 30 passes through the first clamping protrusion 11 and is threaded to the first clamping protrusion 11. The clamping area is located between the first locking bolt 20 and the second locking bolt 30. Therefore, the material to be processed only needs to be placed in the clamping area, and then the first locking bolt 20 is threaded through the first clamping protrusion 11 and locked to the first clamping protrusion 11, and the second locking bolt 30 is threaded through the first clamping protrusion 11 and locked to the first clamping protrusion 11, until the material is clamped and fixed between the first clamping and positioning parts and the second clamping and positioning part. Then, the mounting base 10 is fixedly mounted on the chuck 200 of the lathe, and the material can be processed. After material processing is completed, loosening the first locking bolt 20 and the second locking bolt 30 allows the processed material to be removed from the clamping area. The first and second clamping positioning parts are designed to match the shape of the material to be clamped, enabling the clamping and fixing of various irregularly shaped materials. This ensures that the material can be more easily clamped onto the lathe chuck 200 using the novel fixture 100 of this invention. Clamping is not only quick and effortless, but also more secure and reliable, preventing the risk of loosening and avoiding errors in processing positioning, thus ensuring processing accuracy. Furthermore, it prevents damage to the material, protecting its appearance and improving the material processing yield, thereby reducing production costs. It ensures that various irregularly shaped materials can be clamped and fixed onto the lathe chuck 200, guaranteeing proper material fixing and processing. Furthermore, the clamping area located between the first locking bolt 20 and the second locking bolt 30 allows for a more balanced and stable clamping of the first clamping protrusion 11 and the second clamping protrusion 12 to clamp the material, resulting in a more reasonable clamping effect. Specifically, as follows:
[0022] The first clamping protrusion 11 has a first stepped hole 113 corresponding to the first locking bolt 20, and the second clamping protrusion 12 has a first threaded hole 123 corresponding to the first stepped hole 113. The first locking bolt 20 passes through the first stepped hole 113 and is threaded into the corresponding first threaded hole 123, thereby realizing the connection structure of the first locking bolt 20 passing through the first clamping protrusion 11 and being threaded into the first clamping protrusion 11. This also allows the nut of the first locking bolt 20 to be accommodated in the countersunk hole of the first stepped hole 113, making the structure more reasonable and aesthetically pleasing.
[0023] Furthermore, the first clamping protrusion 11 has a second stepped hole 114 corresponding to the second locking bolt 30, and the second clamping protrusion 12 has a second threaded hole 124 corresponding to the second stepped hole 114. The second locking bolt 30 passes through the second stepped hole 114 and is threaded into the corresponding second threaded hole 124, thereby realizing the connection structure of the second locking bolt 30 passing through the first clamping protrusion 11 and being threaded into the first clamping protrusion 11. This also allows the nut of the second locking bolt 30 to be accommodated in the countersunk hole of the second stepped hole 114, making the structure more reasonable and aesthetically pleasing.
[0024] In detail, in this embodiment, the first clamping and positioning part is a first clamping and positioning groove 111 formed on the first clamping protrusion 11. The second clamping and positioning part is a second clamping and positioning groove 121 formed on the second clamping protrusion 12. The first clamping and positioning groove 111 is directly opposite the second clamping and positioning groove 121, that is, the clamping area is located between the first clamping and positioning groove 111 and the second clamping and positioning groove 121. The first clamping and positioning groove 111 and the second clamping and positioning groove 121 can be designed to match the shape of the material to be clamped and fixed, thereby achieving the ability to clamp and fix various irregularly shaped materials. This ensures that irregularly shaped materials can be more easily clamped onto the lathe chuck 200 using the novel fixture 100 of this invention, resulting in a simpler and more reasonable structure.
[0025] Preferably, in this embodiment, an avoidance through hole 112 is also formed on the groove wall of the first clamping positioning groove 111, and an avoidance groove 122 is also formed on the groove wall of the second clamping positioning groove 121, thereby avoiding the corresponding protruding part on the clamped material, preventing obstruction and interference during the clamping process, and making the structure more reasonable.
[0026] Furthermore, a first clearance groove 115 and a second clearance groove 116 are formed at the connection between the first clamping protrusion 11 and the mounting base 10. The opening of the first clearance groove 115 faces the second clamping protrusion 12, and the opening of the second clearance groove 116 faces away from the opening of the first clearance groove 115, and the second clearance groove 116 is parallel to the first clearance groove 115. Thus, the clearance gap formed by the first clearance groove 115 and the second clearance groove 116 prevents the first clamping protrusion 11 from undergoing slight deformation and swinging in the direction of moving closer to or away from the second clamping protrusion 12, so as to clamp or release the material. Furthermore, a third clearance groove 125 and a fourth clearance groove 126 are formed at the connection between the second clamping protrusion 12 and the mounting base 10. The opening of the third clearance groove 125 faces the first clearance groove 115, and the opening of the fourth clearance groove 126 faces away from the opening of the third clearance groove 125. Both the third clearance groove 125 and the fourth clearance groove 126 are parallel to the first clearance groove 115. Thus, the clearance gap formed by the third clearance groove 125 and the fourth clearance groove 126 prevents the second clamping protrusion 12 from undergoing slight deformation and oscillation in the direction of approaching or moving away from the first clamping protrusion 11, thereby clamping or releasing the material. This achieves the oscillation of the first clamping protrusion 11 and the second clamping protrusion 12 towards or away from each other to clamp or release the material, resulting in a safer and more reasonable structure.
[0027] Alternatively, in this embodiment, the ends of the first clamping protrusion 11 and the second clamping protrusion 12 away from the mounting base 10 are each formed with a plurality of positioning protrusions 14 in a direction away from the mounting base 10. The positioning protrusions 14 can help position the part that contacts the material, so that the clamping and fixing of the material between the first clamping protrusion 11 and the second clamping protrusion 12 is more stable and firm, and the structure is more reasonable.
[0028] The working principle of the novel clamp 100 of this utility model will be described in detail with reference to the accompanying drawings:
[0029] First, place the material to be processed in the clamping area. Then, insert the first locking bolt 20 through the first stepped hole 113 and thread it into the corresponding first threaded hole 123. Insert the second locking bolt 30 through the second stepped hole 114 and thread it into the corresponding second threaded hole 124 until the material is clamped and fixed between the first clamping positioning groove 111 and the second clamping positioning groove 121. Then, fix the mounting base 10 on the lathe chuck 200, and the material can be processed.
[0030] After the material processing is completed, loosen the first locking bolt 20 and the second locking bolt 30 to remove the processed material from the clamping area.
[0031] The novel clamp 100 of this utility model has a first clamping protrusion 11 and a second clamping protrusion 12 protruding from the mounting base 10. The first clamping protrusion 11 and the second clamping protrusion 12 are arranged side by side with a gap. The first clamping protrusion 11 has a first clamping positioning part facing the second clamping protrusion 12, and the second clamping protrusion 12 has a second clamping positioning part facing the first clamping protrusion 11. The first clamping positioning part and the second clamping positioning part are arranged opposite each other, and a clamping area is formed between the first clamping positioning part and the second clamping positioning part. The first locking bolt 20 passes through the first clamping protrusion 11 and is threaded to the first clamping protrusion 11, and the second locking bolt 30 passes through the first clamping protrusion 11 and is threaded to the first clamping protrusion 11. The clamping area is located between the first locking bolt 20 and the second locking bolt 30. Then, simply place the material to be processed in the clamping area, then thread the first locking bolt 20 through the first clamping protrusion 11 and lock it to the first clamping protrusion 11, and thread the second locking bolt 30 through the first clamping protrusion 11 and lock it to the first clamping protrusion 11, until the material is clamped and fixed between the first clamping positioning part and the second clamping positioning part. Then, fix the mounting base 10 on the chuck 200 of the lathe, and the material can be processed. After the material is processed, loosen the first locking bolt 20 and the second locking bolt 30, and the processed material can be taken out from the clamping area. The first and second clamping and positioning parts are designed to match the shape of the material to be clamped and fixed, thus enabling the clamping and fixing of various irregularly shaped materials. This ensures that the material can be more easily clamped onto the lathe chuck 200 using the novel fixture 100, resulting in quick and easy clamping, and a more secure and reliable clamping, preventing the risk of loosening, avoiding errors in machining positioning, and ensuring precise machining. Furthermore, it prevents damage to the material, ensuring its intact appearance, improving the yield rate of material processing, and reducing production costs. It ensures that various irregularly shaped materials can be clamped and fixed onto the lathe chuck 200, guaranteeing proper material fixing and processing.
