Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, and in particular to a batch machining fixture for CNC machines of tie rods. Background Technology

[0002] CNC machine, short for Computer Numerical Control machine tool, is a type of automated machine tool controlled by a program. CNC machine can logically process programs (G code) with control codes or other symbolic instructions, decode them through a computer, and tell the CNC machine tool which Cartesian position coordinates to use for machining tools, control the feed rate of the tool and the spindle speed, so that the machine tool can perform cutting, drilling and other operations on the workpiece.

[0003] Existing CNC machines require fixtures to clamp the product before machining. For example, when machining a tie rod, the tie rod fixture is first installed on the CNC machine, then the tie rod is clamped into the fixture, and finally machining is performed. However, existing tie rod fixtures can only clamp one workpiece at a time, resulting in low machining efficiency. Furthermore, their dimensions are fixed, and if different sizes of tie rods need to be machined, fixtures of the corresponding specifications must be changed, which is quite cumbersome. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a tie rod batch processing fixture for CNC machines.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A CNC machine tool tie rod batch processing fixture includes:

[0007] The base allows it to be mounted on a CNC machine;

[0008] Multiple clamping grooves are arranged along the length of the base and are formed on one side of the upper surface of the base;

[0009] The clamping structure is movably disposed on one side of the clamping groove, wherein multiple pull rods are inserted into the clamping groove and then pressed against the other side of the clamping groove by the clamping structure.

[0010] As described above, a CNC machine tool tie rod batch processing fixture includes a clamping structure comprising a first guide slope having an inner sidewall of the clamping groove, a clamping strip slidably attached to the first guide slope, and a locking structure disposed between the clamping strip and the clamping groove for fixing their relative positional relationship.

[0011] As described above, a CNC machine tool tie rod batch processing fixture includes a locking structure comprising multiple locking countersunk through holes on the clamping bar, corresponding locking screws passing through the locking countersunk through holes, and multiple connecting screw holes on the bottom wall of the clamping groove. The locking screws pass through the locking countersunk through holes and are screwed onto the connecting screw holes.

[0012] In the CNC machine tool tie rod batch processing fixture described above, the diameter of the locking countersunk through hole is larger than the diameter of the locking screw.

[0013] As described above, a CNC machine tool tie rod batch processing fixture has three locking countersunk through holes, which are respectively opened at the middle point of the clamping strip and at both ends in the length direction. The number of locking screws and connecting screw holes are correspondingly set.

[0014] As described above, a CNC machine tool tie rod batch processing fixture has a second guide slope on one side of the clamping strip that can fit against the first guide slope.

[0015] As described above, in a CNC machine tool for batch processing of tie rods, the height of the clamping strip is set to correspond to the depth of the clamping groove.

[0016] As described above, a CNC machine tool tie rod batch processing fixture has 6 clamping slots, and the number of clamping structures is set accordingly to the number of clamping slots.

[0017] As described above, a CNC machine tool tie rod batch processing fixture has an ejection groove on the upper surface of the base located at one end of the clamping groove.

[0018] The beneficial effects of this utility model are: the structure of this application is simple, and by arranging multiple clamping slots on the base, multiple pull rods can be clamped at one time for processing, which greatly improves the processing efficiency; moreover, the clamping structure is movable, and the relative position relationship between the clamping structure and the clamping slots can be freely adjusted according to the specific size of the pull rod, so that most pull rods of different sizes can be clamped, which is practical and convenient.

[0024] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1 to 4 As shown in the figure, this application provides a CNC machine tool tie rod batch processing fixture, including:

[0026] Base 1, which can be installed on a CNC machine;

[0027] Multiple clamping grooves 2 are arranged along the length of the base 1 and are formed on one side of the upper surface of the base 1;

[0028] The clamping structure 3 is movably disposed on one side of the clamping groove 2. After the multiple pull rods 100 are inserted into the clamping groove 2, they are pressed against the other side of the clamping groove 2 by the clamping structure 3.

[0029] By arranging multiple clamping slots 2 on the base 1, multiple pull rods 100 can be clamped at once for processing, greatly improving processing efficiency; and the clamping structure 3 is movable, so the relative position between the clamping structure 3 and the clamping slot 2 can be freely adjusted according to the specific size of the pull rod 100, so that most different sizes of pull rods 100 can be clamped, which is practical and convenient.

[0030] Furthermore, the clamping structure 3 includes a first guide slope 31 on one inner side wall of the clamping groove 2, a clamping strip 32 slidably attached to the first guide slope 31, and a locking structure 4 disposed between the clamping strip 32 and the clamping groove 2 to fix their relative positional relationship.

[0031] Specifically, the locking structure 4 includes multiple locking countersunk through holes 41 opened on the clamping strip 32, corresponding locking screws 42 passing through the locking countersunk through holes 41, and multiple connecting screw holes 43 opened on the bottom wall of the clamping groove 2. The locking screws 42 pass through the locking countersunk through holes 41 and are screwed onto the connecting screw holes 43.

[0032] The clamping strip 32 also has a second guide slope 33 on one side that can fit into the first guide slope 31.

[0033] When clamping, first loosen the locking screw 42 upwards so that the clamping strip 32 can slide upwards along the first guide slope 31 through the second guide slope 33, increasing the distance between the clamping strip 32 and the clamping groove 2. Then, insert the pull rod 100 into the clamping groove 2 and make one side of it close to the other side of the clamping groove 2. Then, tighten the locking screw 42 downwards, which will drive the clamping strip 32 to slide downwards along the first guide slope 31 through the second guide slope 33 and approach the pull rod 100 until the clamping strip 32 is pressed against the other side of the pull rod 100, thus completing the clamping. It is practical and convenient.

[0034] Specifically, the diameter of the locking countersunk hole 41 is larger than the diameter of the locking screw 42. This facilitates the adjustment of the position of the clamping strip 32.

[0035] Specifically, there are three locking countersunk holes 41, located at the midpoint of the clamping strip 32 and at both ends along its length. The number of locking screws 42 corresponds to the number of connecting screw holes 43. This ensures the clamping stability of the clamping strip 32.

[0036] Specifically, the height of the clamping strip 32 is set accordingly to the depth of the clamping groove 2.

[0037] In this embodiment, the number of clamping grooves 2 is 6, and the number of clamping structures 3 is set accordingly to the number of clamping grooves 2.

[0038] Furthermore, an ejection groove 5 is also provided on the upper surface of the base 1 at one end of the clamping groove 2. The ejection groove 5 facilitates the ejection of the processed pull rod from the clamping groove 2, making it practical and convenient.

[0039] In summary, the embodiments of this application, by arranging multiple clamping slots 2 on the base 1, can clamp multiple pull rods 100 at one time for processing, greatly improving processing efficiency; and the clamping structure 3 is movably arranged, so the relative positional relationship between the clamping structure 3 and the clamping slots 2 can be freely adjusted according to the specific size of the pull rod 100, so that most pull rods 100 of different sizes can be clamped, which is practical and convenient.
