Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, and in particular to a side lock batch machining fixture for CNC machines. 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 edge locks, the edge lock fixture is first installed on the CNC machine, then the edge lock is clamped onto the fixture, and finally machining is performed. However, existing edge lock fixtures can only clamp one workpiece at a time, resulting in low machining efficiency. Furthermore, their dimensions are fixed, and if different sizes of edge locks need to be machined, fixtures of the corresponding specifications must be changed, which is very cumbersome. Summary of the Invention

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

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

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

[0008] Spacer protrusions are arranged along the length of the base and protrude from the upper surface of the base, with a clamping space formed between adjacent spacer protrusions;

[0009] A limiting strip is connected to the upper surface of the base and fits against one side of the spacer protrusion;

[0010] A clamping structure is movably mounted on the upper surface of the base on the other side of the spacer protrusion. Multiple side locks are placed into the clamping space and then pressed against the limiting strip by the clamping structure.

[0012] As described above, a CNC machine edge lock batch processing fixture includes a locking structure comprising multiple locking countersunk through holes on the clamping strip, corresponding locking screws passing through the locking countersunk through holes, and multiple connecting screw holes on the upper surface of the base. The locking screws pass through the locking countersunk through holes and are screwed onto the connecting screw holes.

[0013] As described above, a CNC machine edge lock 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 set accordingly.

[0014] As described above, a CNC machine edge lock batch processing fixture is provided with a first guide slope on the side of the guide flange near the spacer protrusion, and a second guide slope that can fit with the first guide slope on the clamping strip.

[0015] As described above, in a CNC machine edge lock batch processing fixture, the height values ​​of the limiting strip and the clamping strip are set correspondingly to the height values ​​of the spacer protrusions.

[0016] As described above, a CNC machine edge lock batch processing fixture is provided with an insertion structure between the limiting strip and the upper surface of the base.

[0017] As described above, a CNC machine edge lock batch processing fixture includes a plurality of insertion slots formed on the upper surface of the base, and insertion protrusions protruding from the lower surface of the limiting strip and capable of being inserted into the insertion slots accordingly.

[0018] As described above, a CNC machine edge lock batch processing fixture is provided with a snap-fit ​​structure between the limiting strip and the spacer protrusion.

[0020] The beneficial effects of this utility model are: the structure of this application is simple. By arranging multiple spaced protrusions on the base to form multiple clamping spaces, multiple side locks can be placed for processing at one time, which greatly improves the processing efficiency; and the clamping structure is movable, so the relative position relationship between the clamping structure and the clamping space can be freely adjusted according to the specific size of the side lock, so that most side locks of different sizes can be clamped, which is practical and convenient.

[0027] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0028] Please see Figures 1 to 5 As shown in the figure, this application provides a CNC machine edge lock batch processing fixture, including:

[0029] Base 1, which can be installed on a CNC machine;

[0030] Spacer protrusions 2 are arranged along the length of the base 1 and protrude from the upper surface of the base 1, and a clamping space 20 is formed between two adjacent spacer protrusions 2;

[0031] The limiting strip 3 is connected to the upper surface of the base 1 and attached to one side of the spacer protrusion 2;

[0032] The clamping structure 4 is movably disposed on the upper surface of the base 1 on the other side of the spacer protrusion 2. After the multiple side locks 100 are respectively placed into the clamping space 20, they are pressed onto the limiting strip 3 by the clamping structure 4.

[0033] By arranging multiple spaced protrusions 2 on the base 1 to form multiple clamping spaces 20, multiple side locks 100 can be placed at one time for processing, greatly improving processing efficiency; and the clamping structure 4 is movable, so the relative position between the clamping structure 4 and the clamping space 20 can be freely adjusted according to the specific size of the side lock 100, so that most side locks 100 of different sizes can be clamped, which is practical and convenient.

[0034] Furthermore, the clamping structure 4 includes a guide flange 41 disposed on one side of the upper surface of the base 1, a plurality of clamping strips 42 slidably attached to the guide flange 41 near the spacer protrusion 2, and a locking structure 5 disposed between the clamping strips 42 and the base 1 for fixing their relative positional relationship.

[0035] Specifically, the locking structure 5 includes multiple locking countersunk through holes 51 opened on the clamping strip 42, corresponding locking screws 52 passing through the locking countersunk through holes 51, and multiple connecting screw holes 53 opened on the upper surface of the base 1. The locking screws 52 pass through the locking countersunk through holes 51 and are screwed onto the connecting screw holes 53.

[0036] The guide flange 41 is provided with a first guide slope 410 on the side near the spacer protrusion 2, and the clamping strip 42 is provided with a second guide slope 420 that can fit with the first guide slope 410.

[0037] When clamping, first loosen the locking screw 52 upwards so that the clamping strip 42 can slide upwards along the first guide slope 410 through the second guide slope 420, increasing the distance between the clamping strip 42 and the clamping space 20. Then, insert the side lock 100 into the clamping space 20 and make one side of it close to the side of the limiting strip 3. Then, tighten the locking screw 52 downwards, which will drive the clamping strip 42 to slide downwards along the first guide slope 410 through the second guide slope 420 and approach the side lock 100 until the clamping strip 42 is pressed against the other side of the side lock 100, thus completing the clamping. It is practical and convenient.

[0038] In this embodiment, the diameter of the countersunk hole 51 is larger than the diameter of the locking screw 52. This facilitates the adjustment of the position of the clamping strip 42.

[0039] Furthermore, the number of locking countersunk through holes 51 is three, respectively located at the midpoint of the clamping strip 42 and at both ends along its length. The number of locking screws 52 and connecting screw holes 53 are correspondingly provided. This ensures the clamping stability of the clamping strip 42.

[0040] Specifically, the height values ​​of the limiting strip 3 and the clamping strip 42 are set accordingly to the height value of the spacer protrusion 2.

[0041] Furthermore, a plug-in structure 6 is provided between the limiting strip 3 and the upper surface of the base 1.

[0042] Specifically, the plug-in structure 6 includes a plurality of plug-in slots 61 formed on the upper surface of the base 1, and plug-in protrusions 62 protruding from the lower surface of the limiting strip 3 and capable of being inserted into the plug-in slots 61.

[0043] Furthermore, a snap-fit ​​structure 7 is provided between the limiting strip 3 and the spacer protrusion 2.

[0044] Specifically, the snap-fit ​​structure 7 includes a snap-fit ​​groove 71 formed on one side of the spacer protrusion 2, and a snap-fit ​​protrusion 72 protruding on the side of the limiting strip 3 near the spacer protrusion 2 and capable of being inserted into the snap-fit ​​groove 71.

[0045] During assembly, move the limiting strip 3 to an angled position above the spacer protrusion 2, then align the insertion protrusion 62 with the insertion slot 61 and the locking protrusion 72 with the locking slot 71. Next, move the limiting strip 3 downwards until the insertion protrusion 62 is inserted into the insertion slot 61 and the locking protrusion 72 is inserted into the locking slot 71. This completes the assembly and is practical and convenient. Furthermore, once the side lock 100 is manufactured, the limiting strip 3 can be removed, allowing the side lock 100 to be easily removed from one side of the clamping space 20. Then, the limiting strip 3 can be reinstalled, making the process quick and easy.

[0046] In summary, the embodiments of this application, by arranging multiple spaced protrusions 2 on the base 1 to form multiple clamping spaces 20, can place multiple side locks 100 for processing at one time, greatly improving processing efficiency; and the clamping structure 4 is movably arranged, and the relative positional relationship between the clamping structure 4 and the clamping space 20 can be freely adjusted according to the specific size of the side lock 100, so that most side locks 100 of different sizes can be clamped, which is practical and convenient.
