Description

Technical Field

[0001] The utility model relates to the technical field of CNC machining fixture equipment, in particular to a CNC machining fixture with a flat inner cavity structure. Background Art

[0002] A tablet computer, also known as a portable computer, is a small, portable personal computer that uses a touch screen as its basic input device. The touch screen (also known as digital tablet technology) it has allows users to perform operations through a stylus or digital pen instead of a traditional keyboard or mouse. Users can input through built-in handwriting recognition, an on-screen soft keyboard, voice recognition or a real keyboard.

[0003] Application number CN202220614262.7 discloses a clamping jig for mounting PCBA boards of tablet computers, comprising a jig body, two grooves 1 being provided on both sides of the top of the jig body, heat dissipation holes being provided on the front and rear sides of the top of the jig body, a plurality of avoidance holes being provided at the bottom of the inner cavity of the jig body, a through hole 1 being provided at each of the four corners of the top of the jig body, a movable plate being slidably connected to the inner cavity of the through hole 1, a spring 1 being provided on one side of the movable plate, and the two ends of the spring 1 being fixedly connected to the jig body and the movable plate, respectively. The utility model has the advantage of being easy to operate. In actual use, only one person is required to complete all operations. The operation is easy and the fixation is good, so that the PCBA board is not easily separated from the tooling jig or tilted, so that the precision of the processed PCBA board is higher, the service life of the jig is extended, the user is more convenient to use, and the practicality of the jig is improved.

[0004] The above document discloses a clamping jig for mounting PCBA boards on tablet computers, which has the following defects: during use, the jig fixes the limit plate through the connecting plate, and the PCBA board is fixed through the limit plate. The jig body limits the PCBA board through groove 1. However, when the models of the PCBA boards are different, when the PCBA boards have irregular concave and convex surfaces, the movable range of the limit plate and the connecting plate of this structure is fixed. Therefore, this structure cannot adapt to different models of PCBA boards for effective fixation, which reduces the practicality of the jig.

[0005] It can be seen from this that the existing mounting fixtures do not have the function of effectively fixing PCBA boards of different models. It is necessary to improve the existing deficiencies and provide a fixture that can effectively fix PCBA boards of different models. Utility Model Content

[0006] The purpose of the present invention is to provide a CNC machining jig for a flat plate inner cavity structure to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0008] The utility model is a CNC machining jig for a flat-plate inner cavity structure, comprising an adjusting component, a clamping component and a workpiece, wherein the clamping component is arranged on the upper surface of the adjusting component, the workpiece is placed on the upper surface of the adjusting component, and the clamping component fixes the workpiece above the adjusting component, and the clamping component comprises two groups of protruding rods, the top ends of the two groups of protruding rods are provided with fixing rods, the outer walls of the fixing rods are sleeved with pressure rods, a plurality of limiting grooves are opened on the outer wall of one side of the fixing rod, a clamping ring is inserted on the inner wall of one of the limiting grooves, and clamping blocks are sleeved on the outsides of the two groups of protruding rods. The purpose of such a setting is that during the use of the CNC machining fixture, the workpiece is placed in the groove of the adjustment component, and the slider is driven to slide on the inner wall of the rail by moving the threaded rotating rod. The slider drives the mounting block to move through the threaded rotating rod, and the row rod is driven to move through the mounting block, and the two row rods are shifted to both sides of the workpiece. Both sides of the workpiece are accommodated in the grooves at the top of the two row rods. The threaded rotating rod can be tightened to fix the slider in the rail, and the threaded rotating rod is fixed together with the mounting block and the row rod. The two sides of the workpiece are squeezed and fixed by two sets of clamping blocks. The clamping blocks are fixed to the row rods through the protruding rods. When the thickness of the workpiece protrudes upward, the clamping blocks are moved. When the clamping block is lifted up, the clamping block moves upward outside the convex rod. When the clamping block moves upward, the groove drives the bottom of the compression spring to move upward, and the top of the compression spring is squeezed and contracted by the fixed compression rod. The top two sides of the workpiece are further limited by the compression rod, and the compression rod is fixed to the compression spring through the fixed rod to cooperate and limit each other. The clamping ring is put on the outside of the fixed rod, and then one side of the clamping ring is inserted into a limiting groove close to the upper surface of the compression rod. The upward path of the compression rod is blocked by the surrounding of the clamping ring, so that the compression rod is fixed. This structure facilitates the up and down adjustment of the clamping end height of the compression rod. When the workpiece has an irregular convex surface, the workpiece can be effectively fixed according to this structure, thereby improving the practicality of the jig.

[0009] Furthermore, a groove is formed on the top outer wall of the clamping block, and a compression spring is sleeved on the outer walls of the protruding rod and the fixed rod, with the top end of the compression spring located on the bottom surface of the compression rod. This arrangement is designed to ensure that when the clamping block is pulled upward during use of the CNC machining jig, the clamping block moves upward outside the protruding rod, and when the clamping block moves upward, the groove drives the bottom end of the compression spring to move upward.

[0010] Furthermore, the adjustment assembly includes a base plate with steel rails fixed to the top and outer walls of both sides of the base plate. Two sliders are slidably connected to the top inner walls of the two rails. This arrangement allows the CNC machining fixture to be used by placing a workpiece in the groove of the adjustment assembly. The sliders are driven by the threaded rotating rod to slide along the inner walls of the rails. The sliders, driven by the threaded rotating rod, move the mounting blocks, which in turn drive the rods, shifting the two rods to either side of the workpiece.

[0011] Furthermore, a threaded rod is threaded onto the inner wall of the slider's top, and a mounting block is sleeved onto the outer wall of the rod. The mounting blocks contact the upper and lower surfaces of the slider and the rod, respectively. This arrangement allows the slider to be secured to the rail by tightening the rod during use, securing the rod, the mounting block, and the rod together.

[0012] Furthermore, a row of rods is installed at the bottom ends of the two mounting blocks in each row, and the two row of rods are slidably connected to the inner walls of both sides of the bottom plate. The purpose of this arrangement is that during the use of the CNC machining jig,

[0013] Furthermore, the two sets of protruding rods are evenly arranged on the upper surface of the rod arrangement. The workpiece is placed on the inner wall of the top side where the two rod arrangements are close. The bottom sides of the two sets of clamping blocks respectively abut against the outer walls of the top side of the workpiece, and one end of the pressure rod is located on the upper surface of the workpiece. The purpose of this arrangement is that during use of the CNC machining jig, the threaded rotating rod, the mounting block, and the rod arrangement are fixed together, the two sets of clamping blocks respectively squeeze and fix the two sides of the workpiece, and the pressure rod further defines the top and two sides of the workpiece.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model is provided with a compression spring, a compression rod and a clamping ring, and two sets of clamping blocks are used to squeeze and fix the two sides of the workpiece respectively. The clamping block moves upward outside the convex rod. When the clamping block moves upward, the groove drives the bottom of the compression spring to move upward, and the top of the compression spring is squeezed and contracted by the fixed compression rod. The compression rod is fixed to the compression spring by the fixing rod and restricted by each other. The upward path of the compression rod is blocked by the surrounding of the clamping ring, so that the compression rod is fixed. This structure facilitates the vertical adjustment of the clamping end height of the compression rod. When the workpiece has an irregular convex surface, the workpiece can be effectively fixed according to this structure, thereby improving the practicality of the tool.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The top ends of the two groups of protruding rods 201 are provided with fixing rods 206. The outer walls of the fixing rods 206 are sleeved with pressure rods 205. Several limiting grooves 207 are opened on the outer wall of one side of the fixing rod 206. A clamping ring 208 is inserted on the inner wall of one of the limiting grooves 207. The outer sides of the two groups of protruding rods 201 are sleeved with clamping blocks 202. The purpose of such arrangement is that during the use of the CNC machining jig, the workpiece 3 is placed in the groove of the adjustment component 1, and the slider 103 is driven to slide on the inner wall of the rail 102 by moving the threaded rotating rod 104. The slider 103 drives the mounting block 105 to move through the threaded rotating rod 104, and drives the row rod 106 to move through the mounting block 105, and shifts the two row rods 106 to both sides of the workpiece 3. Both sides of the workpiece 3 are accommodated in the grooves at the top of the two row rods 106. The threaded rotating rod 104 can be tightened to fix the slider 103 in the rail 102, and the threaded rotating rod 104 is fixed together with the mounting block 105 and the row rod 106. The two sides of the workpiece 3 are squeezed and fixed by two sets of clamping blocks 202. The clamping blocks 202 are fixed on the row rod 106 by the protruding rod 201. When the thickness of the workpiece 3 protrudes upward, the clamping blocks When the workpiece 3 is lifted up, the clamping block 202 moves upward on the outside of the protruding rod 201. When the clamping block 202 moves upward, the groove 203 drives the bottom of the compression spring 204 to move upward. The top of the compression spring 204 is squeezed and contracted by the fixed compression rod 205, and the compression rod 205 is further limited on both sides of the top of the workpiece 3. The compression rod 205 is fixed on the compression spring 204 through the fixing rod 206 to cooperate with each other to limit, and the clamping ring 208 is put on the outside of the fixing rod 206, and then one side of the clamping ring 208 is inserted into a limiting groove 207 close to the upper surface of the compression rod 205. The upward path of the compression rod 205 is blocked by the surrounding of the clamping ring 208, so that the compression rod 205 is fixed. This structure makes it convenient to adjust the height of the clamping end of the compression rod 205 up and down. When the workpiece 3 has an irregular convex surface, the workpiece 3 can be effectively fixed according to this structure, thereby improving the practicality of the jig.

A compression spring 204 is sleeved onto the outer walls of the protruding rod 201 and the fixed rod 206, with the top end of the compression spring 204 resting on the underside of the compression rod 205. This arrangement ensures that when the CNC machining jig is used, the clamping block 202 is lifted upward, moving upward outside the protruding rod 201. As the clamping block 202 moves upward, the groove 203 drives the bottom end of the compression spring 204 upward.
