Description

Technical Field

[0001] This utility model belongs to the field of clamping fixture technology, and specifically relates to a multi-axis clamping fixture for milling machine workpieces. Background Technology

[0002] A clamping fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for machining or inspection; it is also called a jig. In milling machines used in mechanical production, appropriate clamping fixtures are needed to hold the workpiece before machining, thus preventing workpiece displacement during milling. Common clamping fixtures used for milling machines have only a single clamping station, meaning they can only mill a single workpiece in a single operation. However, mechanical production often involves batch processing of the same type of workpiece. This requires operators to repeatedly perform a series of clamping-machining-unloading operations. Compared to multi-axis, multi-station clamping fixtures, single-station clamping fixtures require twice the number of clamping-machining-unloading operations, thus reducing overall production efficiency and increasing the workload of operators.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content

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.

[0027] Please see Figures 1-5 As the first embodiment of this utility model:

[0028] A multi-axis clamping fixture for milling machine workpieces includes: a clamping fixture base assembly 100, which includes a milling machine mounting base plate 101, a fixture base box 103, and a connecting base 106.

[0029] A clamping fixture assembly 200 for clamping and milling workpieces is installed between the two sets of connecting seats 106 on the left and right. The clamping fixture assembly 200 includes a placement seat plate 202 and a clamping screw 204. Several sets of clamping fixture bodies 300 are symmetrically distributed in pairs on the placement seat plate 202.

[0030] The clamping screw 204 is used to drive several sets of clamping fixture bodies 300 distributed in pairs to move simultaneously towards or in opposite directions. The clamping fixture body 300 includes clamping screw holes 302 and clamping plates 303.

[0031] The milling machine mounting base plate 101 is adjusted to move left and right via a left and right moving mechanism. A fixed base plate 102 is mounted on top of the milling machine mounting base plate 101, and a fixture base box 103 is fixedly connected to the fixed base plate 102. (The left and right moving mechanism uses the adjustment method of the existing milling machine, which will not be described in detail here.)

[0032] A set of rotating seats 104 are fixedly connected to the upper ends of both sides of the jig base box 103. An adjusting shaft 105 is fixedly connected to one end of the rotating seat 104 near the center of the jig base box 103. A connecting seat 106 is fixedly connected to one end of the adjusting shaft 105 near the center of the jig base box 103.

[0033] A set of connecting blocks 201 are fixedly connected to both sides of the placement plate 202. A connecting groove 107 is provided on the upper surface of the connecting seat 106. The connecting blocks 201 and the connecting groove 107 are interlocked and fixed by bolts. The clamping fixture assembly 200 is installed in the connecting groove 107 through the connecting blocks 201. According to the milling of the workpiece, the rotating seat 104 drives the connecting seat 106 to rotate, thereby realizing the auxiliary adjustment of the angle of the clamping fixture assembly 200.

[0034] The rear end of the left side of the placement plate 202 is provided with a clamping groove 203. Several sets of bellows covers 205 are installed on the rear side of the placement plate 202 to reduce the amount of waste entering the clamping groove 203. The clamping screw 204 is installed inside the clamping groove 203. Several sets of clamping external threads with different directions are provided on the outer side of the clamping screw 204 and are threadedly connected to the clamping screw hole 302.

[0035] The clamping fixture body 300 also includes a clamping slider 301. A clamping screw hole 302 is opened on the right side of the clamping slider 301. The clamping slider 301 and the clamping groove 203 are movably engaged with each other. The clamping slider 301 and the clamping plate 303 are integrally fixedly connected. Under the drive of the motor, the clamping screw 204 makes the external thread of the clamping screw engage with the thread of the clamping screw hole 302, so that several sets of clamping fixture bodies 300 distributed in pairs can move closer to each other to clamp the workpiece.

[0036] Specifically, the clamping fixture assembly 200 is installed in the connecting groove 107 via the connecting block 201. According to the milling process of the workpiece, the rotating seat 104 drives the connecting seat 106 to rotate, thereby realizing the angle adjustment of the clamping fixture assembly 200. Multiple sets of workpieces are placed between the clamping fixture bodies 300 symmetrically arranged in pairs above the placement seat plate 202. Under the drive of the motor, the clamping screw 204 makes the clamping external thread engage with the clamping screw hole 302, so that the clamping fixture bodies 300 symmetrically distributed in pairs can move closer to each other to clamp the workpieces.

[0037] Secondly, accordion covers 205 are installed on both sides of the clamping fixture body 300 behind the placement plate 202. These covers move with the clamping fixture body 300 as it moves, thereby reducing the intrusion of waste and dust into the clamping slide 203 and enabling multi-station clamping processing.

[0038] Please see Figures 1-3 As a second embodiment of this utility model:

[0039] The lower surface of the fixture base 103 is provided with a collection groove 108 for collecting processing waste. The cross-section of the collection groove 108 is a trapezoidal structure that is wider at the top and narrower at the bottom. A drop groove 109 is provided at the center of the upper surface of the collection groove 108.

[0040] A slot 110 is provided at the lower rear side of the jig base 103. The slot 110 is connected to the drop trough 109. A receiving box 400 for receiving waste material is installed inside the slot 110. The milling operation is located inside the jig base 103, so that a large amount of waste material is collected in the drop trough 109 through the collection trough 108 and falls into the receiving box 400 through the drop trough 109, so that the receiving box 400 can receive and collect the waste material.

[0041] Based on the first embodiment described above, the milling of the workpiece is further located within the fixture housing 103, causing a large amount of waste material to be collected in the collection groove 108 and then falling into the drop groove 109. The receiving box 400 is installed in the box groove 110 and falls into the receiving box 400 through the drop groove 109, thereby assisting in the collection of waste material.

[0042] 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.
