Description

Technical Field

[0001] The utility model relates to the technical field related to wrench processing equipment, in particular to a material clamp used for automatic processing equipment for movable wrenches. Background Art

[0002] In modern manufacturing, high-efficiency and high-precision automated production has become the key to corporate competitiveness. Especially in the processing of precision parts such as adjustable wrenches, the fixture is the basic equipment to ensure processing accuracy, and its design and function directly affect the processing efficiency and product quality. However, the existing material fixture system faces multiple challenges, which include both technical issues and economic considerations.

[0003] First, traditional fixture systems often cannot tightly and stably clamp workpieces such as wrenches. During the processing, the workpiece is prone to loosening due to factors such as vibration, uneven force distribution or unreasonable design, which directly affects the processing accuracy and thus the quality of the product. Especially when processing workpieces with complex shapes and precision requirements such as adjustable wrenches, slight displacements may lead to processing failures, increase scrap rates, and affect production efficiency.

[0004] Secondly, in order to ensure processing accuracy, some fixtures adopt complex design structures. Although this solves the problem of clamping stability to a certain extent, this complexity also increases the difficulty of loading and unloading operations. In a high-speed continuous production environment, the rapid loading and unloading of fixtures is directly related to production efficiency. Overly cumbersome fixtures not only extend the production cycle of a single product, but also increase the labor intensity of operators and reduce the overall efficiency of the production line.

[0005] Furthermore, traditional fixture design is often carried out for a specific type of wrench. Although this one-to-one design mode can ensure processing accuracy to a certain extent, it lacks flexibility when facing diversified product demands. Whenever processing different types of wrenches, the matching material fixture needs to be replaced, which not only increases production costs, but also prolongs the time for product changeover, reducing the ability of the production line to respond to diversified market demands. Utility Model Content

[0007] The technical solution adopted by the utility model to achieve the above purpose is: a material clamp for automatic processing equipment of movable wrenches, including a clamp table, a clamp sheet, a main positioning block, and an auxiliary positioning block, wherein the clamp table and the clamp sheet both include two groups that maintain a symmetrical arrangement.

[0008] The two groups of the clamp tables are fixedly assembled on the clamp body in a detachable manner, wherein at least one group of the clamp tables is fixedly combined with the movable parts of the clamp body, and the clamp plate is fixedly assembled on the inner side surface of the clamp table in a detachable manner, and the wrench body is clamped between the two groups of the clamp plates.

[0009] The main positioning block is assembled on one group of the clamp pieces, and the main positioning block is inserted and nested with the assembly through hole of the wrench body.

[0010] The auxiliary positioning block is detachably mounted on one of the clamping tables, and the inner side surface of the auxiliary positioning block is kept in nested contact with the handle of the wrench body.

[0011] In some of the implementations, in order to ensure that the two sets of clamping plates can be stably installed on the corresponding clamping tables and avoid the clamping plates from loosening when processing the clamped wrench body, the following technical solutions are provided.

[0012] The inner side surface of the fixture table is provided with a wedge-shaped positioning groove, and the wedge-shaped positioning groove extends to the front side of the fixture table. The fixture sheet is provided with a wedge-shaped positioning seat which is nested and matched with the wedge-shaped positioning groove.

[0013] In some of the implementations, in order to ensure that the inner side of the clamp piece can fit tightly with the side of the wrench body and that the main positioning block can be stably installed on the clamp piece to accurately position the wrench body, the following technical solution is provided.

[0014] The inner side surface of the clamp plate is provided with a matching inclined surface that is tightly fitted with the wrench body. One group of the clamp plates is provided with a positioning through hole, and the main positioning block is interference fit with the positioning through hole. Another group of the clamp plates is provided with a yield groove that is nested and matched with the positioning block.

[0015] In some of the implementations, in order to ensure that the auxiliary positioning block can be stably installed on one of the sets of fixture tables, the following technical solutions are provided.

[0018] The auxiliary positioning block is provided with an obliquely arranged positioning notch, and the positioning notch is nested and matched with the handle of the wrench body.

[0019] Beneficial effects of the utility model:

[0020] 1. Improve clamping stability and processing accuracy: By adopting a symmetrically arranged fixture table and fixture piece, combined with the design of the main positioning block and the auxiliary positioning block, this solution can achieve a tight and stable clamping of the main body of the adjustable wrench. In particular, the nested combination of the main positioning block and the assembly through hole of the wrench body, and the nested abutment of the auxiliary positioning block on the wrench handle, jointly ensure high-precision positioning during the processing process, effectively avoiding processing errors caused by unstable clamping, and the combination of the wedge-shaped positioning groove and the wedge-shaped positioning seat ensures the stability of the fixture under the action of processing force, reduces the processing error caused by fixture displacement, and improves the processing quality.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-6 The material fixture used for the automatic processing equipment of the movable wrench includes a fixture table 1, a fixture plate 2, a main positioning block 3, and an auxiliary positioning block 4. The fixture table 1 and the fixture plate 2 both include two groups that maintain a symmetrical arrangement.

[0032] Two sets of clamp tables 1 are fixedly assembled on the clamp body in a detachable manner, wherein at least one set of clamp tables 1 is fixedly combined with the movable parts of the clamp body, and the clamp plate 2 is fixedly assembled on the inner side of the clamp table 1 in a detachable manner, and the wrench body 5 is clamped between the two sets of clamp plates 2.

[0033] The main positioning block 3 is assembled on one set of the clamp pieces 2 , and the main positioning block 3 is nested and plugged with the assembly through hole 51 of the wrench body 5 .

[0034] The auxiliary positioning block 4 is detachably mounted on one of the fixture tables 1 , and the inner side surface of the auxiliary positioning block 4 is nested and abutted against the handle 52 of the wrench body 5 .

[0035] Both sets of fixture tables 1 are fixedly assembled to the fixture body by bolts A11 and bolts B12, and at least one set is connected to the movable parts of the fixture body. When the movable parts drive the corresponding fixture tables 1 to move, the spacing between the two sets of fixture tables 1 and the fixture plates 2 can be adjusted to facilitate the installation of the wrench body 5 to be processed between the two sets of fixture plates 2.

[0036] Bolt A11 penetrates the slope surface on the front side of the fixture table 1 (designed to reduce the weight of the fixture table 1) and is fixedly connected to the fixture body on the rear side, and bolt B12 penetrates the plane on the front side of the fixture table 1 and is fixedly connected to the furniture theme on the rear side. The fixture table 1 is fixed by multiple groups of bolts A11 and bolts B12 to ensure the stability of the fixture table 1 in operation and clamping materials.

[0037] The assembly through hole 51 of the wrench body 5 is used to install the matching threaded shaft. The threaded shaft is driven to rotate to drive the movable chuck with a rack structure to translate and adjust the clamping distance. Therefore, the assembly through hole 51 is usually set as a directional hole, and the main positioning block 3 is also designed as a square structure that is nested and matched with the assembly through hole 51.

[0038] When using an adjustable wrench, in order to facilitate the application of force, the handle 52 of the wrench body 5 is usually designed to be tilted outward. After the two sets of clamp plates 2 have preliminarily positioned the wrench body 5 and the assembly through hole 51 thereon, the handle 52 extends outward to the outside of the clamp plate 2, and the handle 52 tilted and extended outward is positioned by the auxiliary positioning block 4. With the help of the three-point positioning form of the two sets of clamp plates 2 and the auxiliary positioning block 4, the wrench body 5 can be stably installed on the material clamp, effectively avoiding invalid displacement during its processing, and ensuring the stability and accuracy of the processing of the wrench body 5 by the processing equipment.

[0039] Furthermore, since the processing equipment performs processing from the outside of the fixture table 1 toward the wrench body 5, an action will be exerted on the position of the bayonet 53 of the wrench body 5 during the processing, so the handle 52 of the wrench body 5 will have a tendency to move outward, and the design of the auxiliary positioning block 4 can effectively limit the outward movement tendency of the handle 52, thereby ensuring the stability and accuracy of the processing.

[0040] In order to ensure that the two sets of clamping plates 2 can be stably installed on the corresponding clamping platform 1 and avoid the clamping plates 2 from loosening when processing the clamped wrench body 5, the following technical solution is provided.

[0041] A wedge-shaped positioning groove 13 is formed on the inner side of the fixture table 1 . The wedge-shaped positioning groove 13 extends to the front side of the fixture table 1 . A wedge-shaped positioning seat 22 which is nested and matched with the wedge-shaped positioning groove 13 is provided on the fixture plate 2 .

[0042] Since the wedge-shaped positioning groove 13 extends to the front side of the clamp table 1, the wedge-shaped positioning seat 22 of the clamp plate 2 can be inserted into the corresponding wedge-shaped positioning groove 13 from the front side of the clamp table 1 to achieve a fixed combination of the clamp plate 2 and the clamp table 1, so as to effectively prevent the clamp plate 2 from driving the wrench body 5 to jump up and down when the wrench body 5 is processed.

[0043] Also, because the processing equipment processes the wrench body 5 from the outside, the applied force can ensure that the wedge-shaped positioning seat 22 is always located inside the wedge-shaped positioning groove 13 .

[0044] In order to further ensure the stability of the assembly of the clamp plate 2 on the clamp table 1 , the clamp plate 2 can be effectively fixed by means of a bolt C21 inserted from the rear of the clamp table 1 and kept screwed with the clamp plate 2 .

[0045] In order to maximize the contact and action area between the clamp piece 2 and the wrench body 5 and prevent the clamp piece 2 from interfering with the running processing equipment, a clearance gap 23 is opened on the top of the clamp piece 2, and the clearance gap 23 is located outside the bayonet 53 of the wrench body 5.

[0046] In order to ensure that the inner side surface of the clamp plate 2 can fit closely with the side surface of the wrench body 5 and to ensure that the main positioning block 3 can be stably installed on the clamp plate 2 to accurately position the wrench body 5, the following technical solution is provided.

[0047] The inner side surface of the clamp piece 2 is provided with a matching inclined surface 24 which is tightly fitted with the wrench body 5. One group of the clamp pieces 2 is provided with a positioning through hole 25, and the main positioning block 3 maintains an interference fit with the positioning through hole 25. Another group of the clamp pieces 2 is provided with a clearance groove 26 which is nested and matched with the positioning block.

[0048] The matching inclined surface 24 is closely fitted with the side of the wrench body 5, which can further increase the contact area between the two and ensure that the clamping piece 2 tightly clamps the wrench. The setting of the positioning through hole 25 can ensure that the main positioning block 3 is stably installed therein, and the two are combined in an interference fit manner, which can effectively prevent the positioning block from loosening under long-term vibration. The other set of clamping pieces 2 is provided with a clearance groove 26, which can prevent the positioning block from colliding with the clamping piece 2 too early and affecting the clamping effect on the wrench body 5 when the two sets of clamping pieces 2 are close to each other.

[0049] In order to ensure that the auxiliary positioning block 4 can be stably installed on one set of the fixture tables 1, the following technical solution is provided.

[0050] An assembly plane 14 is provided at the bottom of one group of fixture tables 1 , and an adjustment pad 41 is arranged between the auxiliary positioning block 4 and the assembly plane 14 . The auxiliary positioning block 4 , the adjustment pad 41 , and the assembly plane 14 are kept in a fixed combination.

[0051] The setting of the assembly plane 14 can ensure that the auxiliary positioning block 4 is stably installed thereon, and the adjustment pad 41 can be selected with different thicknesses to adjust the distance of the auxiliary positioning block 4 extending out of the assembly plane 14, so that the auxiliary positioning block 4 can be effectively fitted and positioned with the handle 52 extending outward.

[0052] The auxiliary positioning block 4 and the adjusting pad block 41 are fixed to a fixture table 1 provided with an assembly plane 14 by means of bolts D of three lengths, wherein the No. 1 bolt D42 sequentially passes through the plane of the auxiliary positioning block 4 and the adjusting pad block 41 and is screwed onto the fixture table 1, the No. 2 bolt D43 sequentially passes through the inclined surface (designed for weight reduction) of the auxiliary positioning block 4 and the adjusting pad block 41 and is screwed onto the fixture table 1, and the No. 3 bolt D44 directly passes through the adjusting pad block 41 and is screwed onto the fixture table 1.

[0053] In order to ensure that the auxiliary positioning block 4 can effectively position the handle 52 of the wrench body 5 extending out of the clamp plate 2, the following technical solution is provided.

[0054] The auxiliary positioning block 4 is provided with an obliquely arranged positioning notch 45 , and the positioning notch 45 and the handle 52 of the wrench body 5 are nested and matched.

[0055] The design of the positioning notch 45 can ensure that it is effectively fitted with the handle 52 of the wrench body 5 and limit the handle 52 from moving outward, thereby ensuring the stability and accuracy of the processing of the wrench body 5.

[0056] The main positioning block 3 is fixed on the clamp plate 2, and the clamp plate 2, the auxiliary positioning block 4 and the matching adjustment pad 41 are all assembled on the clamp table 1 in a detachable manner, and the details of the clamp plate 2, the main positioning block 3, and the auxiliary positioning block 4 are all designed specifically according to different types of wrench bodies 5. By replacing different types of clamp plates 2, main positioning blocks 3, and auxiliary positioning blocks 4 on the clamp table 1, they can be used to clamp different types of wrench bodies 5, which can effectively improve the applicability of this material clamp.

[0057] During the opening and closing movement of the two sets of clamp tables 1, the wrench body 5 can be quickly clamped and accurately positioned, and it is also convenient to remove the processed wrench body 5 from the material clamp, thereby achieving the operational requirements of fast material unloading.
