Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for mechanical processing, and in particular to a clamping fixture for processing steel ball and wire rod rolls. Background Technology

[0002] In the field of steel ball and wire rod rolling mills, vertical processing schemes are mostly used. However, this processing scheme has many drawbacks for steel ball and wire rod rolling mills with large mass and special shape.

[0003] In terms of processing accuracy, the vertical processing scheme mainly relies on the self-weight of the steel ball wire rod roll for stability, lacking an effective clamping mechanism and a central axis correction device. This makes the steel ball wire rod roll unstable during processing, making it difficult to ensure that the central axis of the roll is coaxial with the central axis of the processing equipment. This leads to uneven force on the roll, affecting processing accuracy and surface quality, and may even cause the roll to be scrapped, increasing production costs.

[0004] From the perspective of processing convenience and safety, steel ball wire rod rolls are usually quite heavy and need to be hoisted to the processing area. Traditional vertical processing methods are difficult to operate, which is not only extremely inconvenient for loading and unloading materials and wastes manpower and resources, but also poses a significant safety risk. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of uneven force on the rolls and poor processing accuracy caused by the traditional vertical processing scheme of steel ball and wire rod rolls, which relies on its own weight for stability and lacks clamping and straightening devices. Moreover, vertical hoisting is inconvenient and dangerous. Therefore, this utility model provides a clamping fixture for processing steel ball and wire rod rolls.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A clamping fixture for processing steel ball and wire rod rolls includes a worktable and a steel ball and wire rod roll. A chuck for clamping the steel ball and wire rod roll is provided at one end of the worktable. The chuck is driven by a four-axis rotary table. A tailstock for pressing the steel ball and wire rod roll is provided at the other end. Two sets of support components for auxiliary support of the steel ball and wire rod roll are provided on the worktable.

[0008] Furthermore, the support assembly includes a support base, on which two sets of support frames are provided, and rollers are rotatably connected to the support frames.

[0009] Furthermore, the upper surface of the support base is provided with two sets of sliding grooves, and the bottom of the support frame is provided with two sets of sliders. The sliding grooves are adapted to the sliders. The support base is provided with first through holes at the four corners. The support base is connected to the T-slot on the workbench by bolts and nuts. The support frame is provided with second through holes at the four corners. The support frame is connected to the support base by bolts passing through the second through holes.

[0010] Furthermore, the upper surface of the support base is provided with two sets of sliding grooves, and the bottom of the support frame is provided with two sets of sliders. The sliding grooves are adapted to the sliders. The support base is provided with first through holes at the four corners. The support base is connected to the T-slot on the workbench by bolts and nuts. A lead screw is rotatably connected between the two ends of the support base. The lead screw is a two-way lead screw. A hand crank is provided at one end of the lead screw. A connecting plate is provided at the middle of the bottom of the support frame. The two sets of connecting plates are connected to the left and right sides of the lead screw by ball nuts respectively.

[0011] Furthermore, the roller abuts against the neck of the steel ball wire rod roll, and by adjusting the distance between the two sets of rollers, the central axis of the steel ball wire rod roll is made coaxial with the central axis of the chuck and the tailstock.

[0012] Furthermore, the chuck, support assembly, and tailstock work together to form a horizontal clamp and support for the steel ball wire rod roll, facilitating central shaft alignment, processing, and loading / unloading.

[0013] Furthermore, the clamping fixture is installed on the gantry machining center, which drives the clamping fixture laterally through a screw drive mechanism to cooperate with the chuck to process the steel ball wire rod roll.

[0014] Beneficial effects: This utility model has the following beneficial effects:

[0015] 1. The steel ball and wire rod rolls are horizontally clamped and supported by the chuck, tailstock and support assembly, which solves the problem of poor stability of the vertical processing scheme. The rollers of the support assembly abut against the roll neck and the adjustable spacing makes the central axis of the roll coaxial with the central axis of the chuck and tailstock, avoiding uneven force on the roll, effectively ensuring processing accuracy and surface quality, reducing roll scrap and reducing production costs;

[0016] 2. The traditional vertical processing method is changed to a horizontal clamping fixture, which avoids the problem of vertical hoisting. The loading and unloading of the rolls is more convenient, reducing the waste of manpower and material resources, reducing the difficulty of operation, and improving the loading and unloading efficiency.

[0017] 3. Compared with the traditional vertical processing solution, the horizontal clamping fixture greatly reduces the safety risks caused by vertically hoisting large steel ball and wire rod rolls, reduces the possibility of safety accidents, and protects the personal safety of operators.

[0018] 4. The support base and worktable of the support assembly are connected by T-slots, bolts and nuts, which facilitates the overall position adjustment. The support and support base are connected by sliding grooves and sliders, and the spacing is controlled by bolts or double screws and hand cranks. The support position and spacing can be flexibly adjusted according to the different sizes of steel ball and wire rod rolls, which enhances the versatility and applicability of the tooling.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1:

[0027] Combination Figure 1 , Figure 2 , Figure 4The fixture shown is a clamping tool for processing steel ball and wire rod rolls, including a worktable 1 and a steel ball and wire rod roll 2. A chuck 3 for clamping the steel ball and wire rod roll 2 is provided at one end of the worktable 1. The chuck 3 is driven by a four-axis rotary table 7. A tailstock 4 for pressing the steel ball and wire rod roll 2 is provided at the other end. Two sets of support components 5 for auxiliary support of the steel ball and wire rod roll 2 are provided on the worktable 1. This overall structural design allows the steel ball and wire rod roll 2 to receive stable support from all directions during processing, effectively solving the problem of poor roll stability in traditional vertical processing schemes, greatly improving processing accuracy, reducing processing errors caused by roll swaying or offset, reducing the risk of roll scrapping, and saving production costs.

[0028] The support assembly 5 includes a support base 501, on which two sets of support frames 502 are provided and tightly connected to the support base 501 to ensure that there is no shaking when supporting the roll. A roller 503 is rotatably connected to the support frame 502. This rotatable connection design allows the roller 503 to rotate flexibly. When the steel ball wire rod roll 2 is placed on the roller 503, the roller 503 abuts against the roll neck of the roll, which can provide stable support force for the roll, share part of the weight of the roll, and further enhance the stability of the roll during the processing.

[0029] The upper surface of the support base 501 has two sets of sliding grooves 504, and the bottom of the support frame 502 has two sets of sliding blocks 505. The sliding grooves 504 and the sliding blocks 505 are adapted to each other. This structure allows the support frame 502 to move flexibly on the support base 501. By adjusting the position of the support frame 502, the distance between the two sets of rollers 503 can be changed, thereby accommodating steel ball wire rod rolls 2 of different lengths and diameters. The support base 501 has first through holes 506 at its four corners. The support base 501 is connected to the T-slots on the worktable 1 by bolts and nuts, ensuring that the support base 501 can move flexibly on the worktable. The stable installation on the worktable 1 also facilitates the adjustment of the position of the support base 501 on the worktable 1 according to processing requirements. The support frame 502 has a second through hole 507 at each of its four corners. The support frame 502 is connected to the support base 501 by bolts passing through the second through holes 507, ensuring that the connection between the support frame 502 and the support base 501 is firm and reliable and will not loosen during processing. This structural design not only improves the versatility of the tooling and can meet the processing requirements of rolls of different specifications, but also enhances the overall stability of the tooling and ensures the smooth progress of the processing.

[0030] The roller 503 abuts against the neck of the steel ball wire rod roll 2, providing a stable support point for the roll. By adjusting the distance between the two sets of rollers 503, the position of the roll can be precisely adjusted so that the central axis of the steel ball wire rod roll 2 is coaxial with the central axis of the chuck 3 and the tailstock 4. This coaxiality is crucial for machining accuracy, as it ensures that the roll is subjected to uniform force during machining and avoids machining errors caused by roll eccentricity.

[0031] The chuck 3, support assembly 5, and tailstock 4 work together to form a horizontal clamping and support for the steel ball wire rod roll 2. Compared with the traditional vertical processing scheme, this horizontal structure has a significant advantage in center axis correction. Since the roll is in a horizontal state, it is easier to accurately correct its center axis using measuring tools and adjustment devices, improving the accuracy and efficiency of correction. During processing, the horizontal support can make the roll more evenly stressed, reduce deformation caused by gravity, and ensure processing accuracy. At the same time, the horizontal structure also greatly facilitates loading and unloading operations. Operators can more easily place the roll on the chuck 3 and support assembly 5, and then tighten and fix it with the tailstock 4, avoiding the high difficulty and safety risks of vertical hoisting, and improving the efficiency and safety of loading and unloading.

[0032] The clamping fixture is mounted on the gantry machining center 6. The screw drive mechanism of the gantry machining center 6 provides lateral drive for the clamping fixture. This screw drive mechanism is characterized by high precision and stability, enabling precise control of the clamping fixture's position and speed. The chuck 3 drives the steel ball / wire bar roll 2 to rotate. During machining, the screw drive mechanism of the gantry machining center 6 drives the clamping fixture to move laterally, coordinating with the rotational movement of the chuck 3 to achieve various machining operations on the roll. This coordination fully leverages the advantages of the gantry machining center 6 and the clamping fixture, improving the automation level and machining accuracy. Simultaneously, the stable support of the clamping fixture reduces roll vibration during machining, improving the surface finish and enabling the machined steel ball / wire bar roll 2 to meet higher precision requirements.

[0033] Example 2:

[0034] Combination Figure 3As shown, based on Embodiment 1, this utility model provides a technical solution: a clamping fixture for processing steel ball wire rod rolls, wherein the upper surface of the support base 501 is provided with two sets of sliding grooves 504, the bottom of the support frame 502 is provided with two sets of sliders 505, the sliding grooves 504 and the sliders 505 are adapted to each other, the support base 501 is provided with first through holes 506 at the four corners, the support base 501 is connected to the T-slot on the worktable 1 by bolts and nuts, a lead screw 508 is rotatably connected between the two ends of the support base 501, the lead screw 508 is a bidirectional lead screw, one end of the lead screw 508 is provided with a hand crank 509, and the support frame 501 is connected to the T-slot on the worktable 1 by bolts and nuts. A connecting plate 510 is provided at the bottom center. The two sets of connecting plates 510 are connected to the left and right sides of the lead screw 508 respectively through ball nuts. Compared with the manual adjustment method in Embodiment 1, this lead screw transmission structure is more precise and convenient. The operator can easily adjust the distance between the two sets of rollers 503 by turning the hand crank 509, and can achieve more precise fine adjustment, which further improves the support and positioning accuracy of the steel ball wire rod roll 2. At the same time, this structure also improves the operator's work efficiency, reduces adjustment time, and enables the tooling to adapt to the processing needs of rolls of different specifications more quickly.
