Description

Technical Field

[0001] This utility model belongs to the field of parts processing, and in particular relates to a quick-change tooling for clamping multiple parts. Background Technology

[0002] Figure 1 This is a semi-finished cold-extruded part for the communications field. Subsequent processing steps require machining the ring-shaped abutment and the holes on its sides. Current machining techniques involve using a vise or pliers to fix the part in place, first securing it to a fixture, machining the ring-shaped abutment to a preset size, then disassembling the part and installing it on another fixture, drilling holes on the sides of the ring-shaped abutment, and finally disassembling the machined part for the next process. This process requires operators to repeatedly disassemble and reassemble the part, making the work tedious and time-consuming, resulting in low processing efficiency and increased costs. While some fixtures exist that allow for quick part replacement, collisions between fixture components and parts are inevitable during the replacement process. Over time, this can affect the fixture's accuracy, and maintenance is complex to maintain the connection structure and reliability between parts. Utility Model Content

[0003] In view of this, the present invention aims to propose a multi-part clamping quick-change tooling to reduce the number of times workers clamp parts when processing the same number of parts, increase the part change speed and the number of parts changed at one time after processing is completed, and thus improve the machine tool utilization rate.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A multi-part clamping quick-change tooling, including

[0006] A base on which multiple leveling units are provided, and the upper surfaces of the multiple leveling units are combined to form a mounting surface. The base is provided with multiple connecting parts.

[0007] The quick-change unit includes a quick-change block and multiple sets of clamping units disposed on the quick-change block. The quick-change block is provided with connectors corresponding to the connecting parts, so that the quick-change unit can be detachably connected to the base. The lower surface of the quick-change block can fit against the mounting surface. The clamping units are arranged in a row. Each set of clamping units includes a fixing hole and an OK clamp. The OK clamp is placed in the fixing hole, and each clamp of the OK clamp faces one side of the hole wall of the fixing hole. The clamp can be close to or away from the hole wall of the fixing hole.

[0008] The base can rotate about a line parallel to the line connecting multiple sets of clamping units.

[0009] Furthermore, the leveling unit is a leveling bolt, and multiple screw holes are opened at the corners of the base. The leveling bolt is screwed to the base, and the lower surface of the quick-change block can abut against the screw head end face of the leveling bolt.

[0010] Furthermore, corresponding positioning posts and positioning sleeves are fixedly provided on the bottom of the quick-change block and the base, respectively.

[0011] Furthermore, each of the fixing holes has a fixing groove, and the fixing hole has a fixing station on both sides of the fixing groove. The OK clamp is fixed in the fixing groove, and the length of the fixing station is less than the length of the part to be processed, so that one edge of the part to be processed can extend into the fixing groove.

[0012] Furthermore, clearance holes are provided at the corners of the fixing groove.

[0013] Furthermore, the depth of the fixing groove is greater than the depth of the fixing hole.

[0014] Furthermore, one of the connectors is located in the middle of the quick-change block, and the number of clamping units on both sides of the connector is different.

[0015] Furthermore, the connecting part is a screw hole opened on the base, and the connecting element is a connecting bolt.

[0016] Furthermore, this quick-change tooling also includes a bridge plate, with two rotating connecting discs fixedly connected to each end of the bridge plate. The rotating connecting discs can rotate synchronously around their own axes, and the base is fixedly mounted on the bridge plate.

[0017] Furthermore, one side edge of each of the two rotating connecting discs extends into a support portion, and the lower ends of both ends of the bridge plate are fixed to the support portion by bolts.

[0018] Compared with the prior art, the multi-part clamping quick-change tooling of this utility model has the following advantages:

[0019] This utility model employs multiple clamping units on the quick-change block, allowing operators to fix multiple parts to be processed onto the quick-change block and detachably connect them via connectors. This enables the quick-change unit to be replaced as a whole when changing parts, allowing multiple parts to be processed to be replaced at once, thereby reducing downtime for changing parts during processing. At the same time, by setting multiple leveling units on the base to form a mounting surface, when the quick-change block collides with the base surface, the mounting surface can be leveled again by the leveling units, ensuring the stability of the quick-change block after installation and reducing the cost of fixture installation and maintenance.

[0020] The rotating base allows all parts on the quick-change block to rotate as a whole, which facilitates drilling on the side of the part to be processed and reduces the number of times the part is clamped.

[0021] The depth of the fixing groove is greater than the insertion of the fixing hole, so that the surface height of the OK clamp is lower than the surface height of the workpiece to be processed, thus avoiding interference between the tool and the OK clamp during the processing.

[0022] By creating clearance holes at the corners of the fixed slot, the OK clamps are prevented from jamming against the side wall of the fixed slot during installation. At the same time, the clamps of the OK clamps can move towards the workpiece to be processed and clamp the workpiece.

[0023] Different numbers of clamping units are set on both sides of the connector in the middle to facilitate the operator in identifying the direction of the quick-change block. Attached Figure Description

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] like Figure 2 , Figure 3 and Figure 4As shown, the multi-part clamping quick-change tooling of this utility model includes a base 1 and a quick-change unit 2 detachably connected to the base 1. Multiple leveling units are provided above the base 1. The upper surface of the leveling unit can be close to or away from the upper surface of the base 1. The upper surfaces of the multiple leveling units form a mounting surface. Optionally, in this embodiment, the leveling unit is a leveling bolt 11 screwed to the base 1. The screw head end face of the leveling bolt 11 serves as the upper surface of the leveling unit. By rotating the leveling bolt 11, the upper surface of the leveling bolt 11 is made to be in the same plane or in a preset position. Those skilled in the art can also directly screw the leveling bolt 11 onto the base 1 and process the upper end face of the screw head of the leveling bolt 11 to the same plane or preset height using a milling cutter or other processing equipment. When unexpected situations such as bumps occur during the disassembly, installation, or movement of the quick-change unit 2, if the bump occurs on the upper surface of the base 1, no treatment is required. If the bump occurs on the leveling bolt 11 and affects the accuracy of the mounting surface, it is only necessary to replace the corresponding leveling bolt 11 or re-process the screw head of the leveling bolt 11, thereby reducing the cost and difficulty of tooling maintenance. In other embodiments, the leveling unit can also be a pad, a plate, etc., which can be fixed on the base 1 by embedding, snap-fitting, etc., and the mounting surface is formed by the upper surfaces of multiple pads and / or plates.

[0037] The quick-change unit 2 includes a quick-change block 21 and multiple clamping units 22 disposed on the quick-change block 21. The quick-change block 21 is provided with a connector corresponding to the connecting part, so that the quick-change unit 2 can be detachably connected to the base 1. Optionally, in this embodiment, the connecting part is a screw hole 12 opened on the base 1, the connector is a connecting bolt, and the quick-change block 21 has a through hole. The connecting bolt passes through the through hole and connects to the screw hole 12 of the base 1, so that the quick-change block 21 is detachably fixed to the base 1, and at this time, the lower surface of the quick-change block 21 is in contact with the mounting surface. In other embodiments, those skilled in the art can also fix the quick-change block 21 to the base 1 by means of buckles, negative pressure suction cups, etc. Figure 5 As shown, in this embodiment, the bottom of the quick-change block 21 and the base 1 are respectively fixed with corresponding positioning posts 13 and positioning sleeves 211. Specifically, a blind hole is opened at the bottom of the quick-change block 21, and the positioning sleeve 211 is embedded in the blind hole. The positioning post 13 is fixed on the upper surface of the base 1, and the height of the positioning post 13 is higher than the mounting surface, so that the positioning post 13 is inserted into the positioning sleeve 211 during installation to position the quick-change block 21. In this embodiment, one of the connecting parts and the corresponding connecting member are placed in the middle of the quick-change block 21, and the number of clamping units 22 on both sides of the connecting member is different, so that the operator can judge the front and back of the quick-change block 21 based on the number of clamping units 22 on both sides.

[0038] like Figure 3As shown, the clamping units 22 are arranged in a row on the quick-change block 21. Each set of clamping units 22 includes a fixing hole 221 and an OK clamp 222. The OK clamp 222 is placed inside the fixing hole 221, and each clamping plate of the OK clamp 222 faces one side of the hole wall of the fixing hole 221. The clamping jaws can approach or move away from the hole wall of the fixing hole 221. In this embodiment, the fixing hole 221 is an elongated hole with a fixing groove 2211 in the middle. Fixing stations 2212 are provided at both ends of the fixing hole 221. The shape of the fixing station 2212 is similar to the shape of the part to be processed, so that the part to be processed can be placed in the fixing station 2212. In this embodiment, the width of the fixing station 2212 is similar to that of the part to be processed, and the length is less than that of the part to be processed, so that the part to be processed extends into the fixing groove 2211, so that the clamping plates of the OK clamp 222 can press tightly on the part to be processed, fixing the part to be processed in the fixing station 2212. In this embodiment, the depth of the fixing groove 2211 is greater than the depth of the fixing hole 221, allowing the upper surface of the OK clamp 222 to be placed within the fixing groove 2211, thus preventing interference between the part and the OK clamp 222 during machining. Clearance holes 2213 are provided at the four corners of the fixing groove 2211. The depth direction of the clearance holes 2213 is the same as the depth direction of the fixing groove 2211, and each clearance hole 2213 is a circular hole with one-quarter of its cross-section inside the fixing groove 2211. This prevents the clamping plates of the OK clamp 222 from jamming against the corners of the fixing groove 2211 during installation and use.

[0039] like Figure 2 As shown, the base 1 can rotate around a line parallel to the line connecting multiple clamping units 22. Optionally, this fixture also includes a bridge plate 3 and two opposing rotating connecting discs 4. One edge of each rotating connecting disc 4 extends a support portion 41 in a opposite direction. The lower surfaces at both ends of the bridge plate 3 are fixedly connected to the support portion 41, and the base 1 is fixedly mounted on the bridge plate 3. The rotating connecting disc 4 is fixedly connected to components such as a three-jaw or four-jaw chuck of the A-axis or B-axis of the CNC machine tool, and drives the fixture to rotate through the chuck. During operation, the parts to be processed are first placed in the fixed station 2212. Then, the OK clamp 222 clamps and fixes the parts in the fixed stations 2212 on both sides at once, thereby reducing the time for operators to clamp the parts to be processed. Finally, the quick change body is fixed to the base 1 with connecting bolts, and the machine tool is started for processing. During the processing of the parts on the quick change body, the operator can fix the subsequent parts to be processed on another quick change body. When the parts on the first quick change body are processed, the second quick change body can be directly replaced, thereby reducing the downtime of the machine tool due to changing parts during processing and thus improving work efficiency.

[0040] The OK clamp 222 includes a wedge block in the middle and clamping plates on both sides. The clamping plates and the wedge block are engaged by inclined surfaces, so that when the wedge block moves, the clamping plates on both sides can move outward or inward, thereby clamping and releasing the workpiece to be processed. Its specific structure is existing technology and will not be described in detail here.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
