Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically a high-precision positioning clamping clamp for a five-axis rotary table head. Background Technology

[0002] In the field of machining, especially in precision machining scenarios involving five-axis rotary tables, the positioning and clamping accuracy of the workpiece is a core factor affecting machining quality.

[0003] Traditional positioning and clamping devices generally suffer from the following technical bottlenecks:

[0004] 1. Insufficient structural stability: Traditional clamp installation methods often rely on a single bolt for fixation. Under the high-speed rotation of the five-axis head or the action of complex cutting forces, the entire device is prone to displacement or loosening, resulting in workpiece positioning deviation.

[0005] 2. Limited positioning accuracy: The adjustment method of the clamping structure lacks precise guiding design. For example, the gap between the slide and the slider is large, or the clamping force is unevenly transmitted, making it difficult to achieve micron-level positioning and failing to meet the high-precision processing requirements of aerospace, precision molds and other industries.

[0006] 3. Low operating efficiency: Some devices require multiple adjustments to the bolt positions and repeated calibration during clamping, resulting in long clamping times and making it difficult to meet the high-efficiency operation requirements of automated production lines.

[0007] 4. Insufficient versatility: Traditional equipment is designed for specific workpiece sizes. When processing parts of different specifications, the entire fixture needs to be replaced, which increases production costs and debugging time. Utility Model Content

[0008] The purpose of this utility model is to provide a high-precision positioning clamping clamp for a five-axis turntable. By setting a base assembly, a mounting assembly, and a clamping assembly, the position adjustment is achieved by the sliding cooperation between the sliding groove on the base and the slider of the clamping assembly. The clamping force is transmitted through the cooperation of bolts and bearings, which solves the problems of low positioning accuracy, insufficient structural stability, and poor adaptability of traditional devices.

[0009] This utility model is achieved through the following technical solution:

[0010] This utility model is a high-precision positioning and clamping clamp for a five-axis turntable, including a base assembly, four mounting components and two clamping components. The base assembly includes a base, the top of which has four sliding grooves, and the bottom of which has four threaded holes and four slots.

[0011] The mounting assembly includes a mounting block, one end of which is fixedly connected to an insert block. The mounting block has a through-hole, and a first bolt is inserted into the through-hole.

[0012] The clamping assembly includes a clamp body, with a downward protrusion at the bottom of the clamp body forming a slider, and downward protrusions at the bottom of both sides of the clamp body forming protrusions. A bearing is fixedly connected to the outer surface of the clamp body, and a second bolt is fitted inside the bearing. A nut is threaded onto the second bolt.

[0013] Furthermore, the two clamping components are arranged opposite each other, with the protrusion slidingly engaging with the top of the base.

[0014] Furthermore, the nut end of the first bolt overlaps the outer surface of the mounting block.

[0015] Furthermore, mounting grooves are provided on both sides of the base assembly, a slider is slidably fitted in the groove, a first bolt is threaded in the threaded hole, and a plug is inserted into the slot.

[0016] Furthermore, a nut is embedded in the mounting groove.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model connects to the clamp body via a bearing using a second bolt, ensuring uniform axial force transmission during rotation and preventing clamp body tilting due to frictional resistance. Combined with the nut embedded in the mounting groove, it achieves precise control of clamping force and high workpiece positioning repeatability. The four mounting components allow for flexible disassembly or adjustment of the workpiece size, making it suitable for installation requirements of different sizes of turntable flanges.

[0019] 2. The mounting components are connected by the insertion of the plug and the slot, and the first bolt is fixed by the threaded hole to form a double locking structure of "pin + bolt". This enhances the tensile strength and torsional stiffness of the connection between the base and the five-axis head of the turntable. The protrusion of the clamping component slides in contact with the top surface of the base, increasing the support area and reducing the overturning moment when the clamp is clamped, effectively resisting cutting vibration.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a high-precision positioning and clamping clamp for a five-axis turntable, comprising a base assembly 1, four mounting assemblies 2, and two clamping assemblies 3.

[0029] The base assembly 1 includes a base 101, which serves as the basic support component of the entire device, providing an installation platform for the mounting assembly 2 and the clamping assembly 3. The top of the base 101 has four sliding grooves 102, which provide sliding tracks for the slider 302 of the clamping assembly 3, allowing the clamping assembly 3 to move smoothly on the base 101 and achieve position adjustment. The bottom of the base 101 has four threaded holes 103 and four slots 105, which engage with the insertion blocks 202 of the mounting assembly 2 to achieve initial positioning of the mounting assembly 2 and the base 101. High installation efficiency: The threaded hole 103 is used to cooperate with the first bolt 203 of the mounting component 2 to fix the mounting component 2. It can also be used to connect the base 101 itself to external equipment. The base component 1 has mounting grooves 104 on both sides. Nuts 306 are embedded in the mounting grooves 104 to provide a foundation for the threaded connection of the second bolt 305 and ensure the transmission of clamping force. A slider 302 is slidably fitted in the sliding groove 102. The first bolt 203 is threadedly fitted in the threaded hole 103. A plug block 202 is inserted into the slot 105. The mounting nut 306 is embedded in the mounting groove 104.

[0030] The base 101 is connected to external equipment (such as a five-axis turntable head) through the threaded hole 103 at the bottom. Bolts are used to pass through the threaded hole 103 and tighten them to ensure that the base 101 is stably installed in the target position.

[0031] Mounting component 2 includes mounting block 201. One end of mounting block 201 is fixedly connected to insert block 202. Mounting block 201 has an opening, and a first bolt 203 is inserted into the opening. The nut end of the first bolt 203 overlaps the outer surface of mounting block 201.

[0032] Insert the insert 202 at one end of the mounting block 201 into the slot 105 at the bottom of the base 101 to initially position the mounting block 201 and the base 101. Then, pass the first bolt 203 through the through-hole of the mounting block 201, with its nut end overlapping the outer surface of the mounting block 201, and screw the other end into the threaded hole 103 of the base 101. Tighten the first bolt 203 to further fix the base 101 through the mounting assembly 2, thereby enhancing the stability of the overall structure.

[0033] The clamping assembly 3 includes a clamp body 301. The bottom of the clamp body 301 protrudes downward to form a slider 302. The bottoms of both sides of the clamp body 301 protrude downward to form protrusions 303. A bearing 304 is fixedly connected to the outer surface of the clamp body 301. A second bolt 305 is sleeved and fitted inside the bearing 304. A nut 306 is threaded on the second bolt 305. The two clamping assemblies 3 are arranged opposite to each other. The protrusions 303 slide and engage with the top of the base 101.

[0034] The sliders 302 of the two clamping components 3 are respectively placed into the slide grooves 102 on the top of the base 101, so that the sliders 302 slide in the slide grooves 102. Since the two clamping components 3 are arranged opposite each other, the clamp body 301 can be pushed to slide on the slide grooves 102 according to the size of the workpiece, and the distance between the two clamping components 3 can be adjusted. At this time, the protrusions 303 on both sides of the bottom of the clamp body 301 slide on the top of the base 101 to help guide the movement direction of the clamp body 301 and ensure smooth movement.

[0035] After adjusting the positions of the two clamping components 3, align the clamp body 301 with the part of the workpiece that needs to be clamped, and rotate the second bolt 305. Since the bearing 304 on the outer surface of the clamp body 301 is sleeved on the second bolt 305, the bearing 304 can reduce the friction when the second bolt 305 rotates, making the rotation smoother. As the second bolt 305 rotates, its threaded engagement with the nut 306 generates an axial force, pushing the clamp body 301 to move towards the workpiece, thereby applying a clamping force to the workpiece. Tighten the nut 306 to make it tightly engage with the second bolt 305, fix the position of the clamp body 301, and ensure that the clamping force continues to act on the workpiece, achieving high-precision positioning and clamping of the workpiece.
