Description

Technical Field

[0001] The present invention relates to the field of discrete manufacturing in intelligent manufacturing, and particularly to a connecting block. Background Art

[0002] In order to reduce costs and increase efficiency, in recent years, there has been a wave of enthusiasm for intelligent manufacturing worldwide. Enterprises in many industries highly rely on automated production lines to achieve automated processing, assembly, and inspection; for example, enterprises in industries such as steel, chemical, pharmaceutical, food and beverage, tobacco, chip manufacturing, electronic assembly, automotive vehicle and parts manufacturing, etc. And in order to establish such an intelligent production line, zero-point positioning devices are usually used in machining workshops to keep the zero point unchanged when the workpiece moves from one station to another, or from one process to another, or from one machine tool to another. This can save the auxiliary time for re-aligning the zero point and is suitable for the machining of large quantities of precision parts. However, the zero-point positioning devices on the market have requirements for the blank size of the workpiece, and some small part blanks cannot be connected to the zero-point positioning devices, so these small parts cannot be processed through the method of intelligent manufacturing. Summary of the Invention

[0003] In view of the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide a connecting block suitable for connecting a zero-point positioning device and a small part blank.

[0004] To achieve the above purpose, the present invention provides a connecting block for connecting a part to be processed and a positioning device. The connecting block has a front surface for connecting to the part to be processed and a back surface for connecting to the positioning device. The connecting block is provided with a first connection hole area for fixing the connecting block and the part to be processed, a second connection hole area for fixing the connecting block and the positioning device, a first limiting hole area for limiting the connecting block and the part to be processed, and a second limiting hole area for limiting the connecting block and the positioning device; the first connection hole area includes several first connection through holes distributed in the middle area of the connecting block and several second connection through holes distributed at both ends of the connecting block in the length direction. Both the first connection through holes and the second connection through holes include a countersunk hole and a through hole connected to each other. One end of the countersunk hole facing away from the through hole extends to the back surface of the connecting block, and one end of the through hole facing away from the countersunk hole extends to the front surface of the connecting block.

The threaded holes are blind hole structures and are opened on the back surface of the connecting block; the first limiting hole area includes several first pin holes distributed around the first connection through holes and second pin holes distributed between the first connection through holes and the second connection through holes. Both the first pin holes and the second pin holes are blind hole structures and are opened on the front surface of the connecting block.

[0005] Further, the counterbores of a plurality of second connection through holes provided at the same edge of the connection block communicate with each other and form a straight notch, and the straight notch is opened on the back surface of the connection block and located at the edge of the connection block.

[0006] Further, among the plurality of second connection through holes provided at the same edge of the connection block, a plurality of perforations are arranged at equal intervals along the width direction of the connection block, and the centers of the plurality of perforations are collinear.

[0007] Further, there are four threaded holes, and the connection lines of the centers of the four threaded holes form a square, and the centers of the counterbores of each of the first connection through holes are all located within the square.

[0008] Further, there are five first connection through holes, one of the first connection through holes is located at the center of the connection block and is a central first connection through hole, and the remaining four first connection through holes are distributed on the outer peripheral side of the central first connection through hole, and the connection lines of the centers of the four first connection through holes form a rectangle.

[0009] Further, the second limiting hole area includes third pin holes distributed between the first connection through holes and the second connection through holes, and the third pin holes are of blind hole structure and are opened on the back surface of the connection block.

[0010] Further, the first pin hole, the second pin hole and the third pin hole have the same diameter and the same depth.

[0011] Further, the diameters of the perforations in the first connection hole area are the same.

[0012] Further, the diameter of the threaded hole in the second connection hole area is smaller than the diameter of the perforation in the first connection hole area.

[0013] As described above, the connection block involved in the present invention has the following beneficial effects:

[0014] The connection block involved in the present application has hole structures such as counterbores, perforations, threaded holes and pin holes, which can conveniently connect the parts to be processed and the positioning device, and is particularly suitable for small parts to be processed.

[0042] This application provides a connecting block 100 for connecting a part to be processed 200 and a positioning device 300, and is particularly suitable for connecting small parts to be processed and a zero-point positioning device. Figure 4 In the view shown, the positioning device 300 is a zero-point positioning disk 301 for installation on a workbench surface 400; the part to be processed 200 is a blank part 201, and the blank part 201 and the zero-point positioning disk 301 are connected together by the connecting block 100 in this application. Therefore, the connecting block 100 has a front surface S1 for connecting to the blank part 201 and a back surface S2 for connecting to the zero-point positioning disk 301. For the convenience of narration, in the following embodiments, the definitions of each direction are as follows: the length direction of the connecting block 100 is defined as the left-right direction, the width direction of the connecting block 100 is defined as the front-back direction, and the thickness direction of the connecting block 100 is defined as the up-down direction; therefore, Figure 1 In the view shown, the left and right sides of the paper surface are the left direction and the right direction respectively, the upper and lower sides of the paper surface are the front direction and the back direction respectively, and the front surface S1 and the back surface S2 of the paper surface are the up direction and the down direction respectively.

[0043] The preferred embodiment of the connecting block 100 is described as follows.

[0044] As Figures 1 to 4 shown, the connecting block 100 is provided with a first connection hole area for fixing the connecting block 100 and the part to be processed 200 (small blank part 201), a second connection hole area for fixing the connecting block 100 and the positioning device 300, a first limiting hole area for limiting the connecting block 100 and the part to be processed 200, and a second limiting hole area for limiting the connecting block 100 and the positioning device 300. The connecting block 100 has a block main body portion in the shape of a cuboid, and the first connection hole area, the second connection hole area, the first limiting hole area, and the second limiting hole area all include several holes opened on the block main body portion.

[0045] Further, the distribution pattern of the holes in the first connection hole area for fixing the connection block 100 and the part to be machined 200 is as follows: As Figures 1 to 3 shown, the first connection hole area includes five first connection through-holes 101 distributed in the middle area of the connection block 100, three second connection through-holes 102 distributed at the left edge of the connection block 100, and three second connection through-holes 102 distributed at the right edge of the connection block 100. Both the first connection through-holes 101 and the second connection through-holes 102 are used to accommodate bolts. The bolts are inserted through the first connection through-holes 101 and the second connection through-holes 102 to fix the connection block 100 and the part to be machined 200. Therefore, both the first connection through-holes 101 and the second connection through-holes 102 include a counterbore 103 and a through-hole 104 that are connected and coaxially arranged. One end of the counterbore 103 facing away from the through-hole 104 extends to the back surface S2 of the connection block 100, and one end of the through-hole 104 facing away from the counterbore 103 extends to the front surface S1 of the connection block 100. The diameter of the counterbore 103 is larger than the diameter of the through-hole 104. The head of the bolt is accommodated in the counterbore 103, and the shaft of the bolt is accommodated in the through-hole 104. Preferably, the depth of the counterbore 103 is greater than the thickness of the head of the bolt, and the diameter of the counterbore 103 is larger than the diameter of the head of the bolt, so that the head of the bolt can be completely accommodated in the counterbore 103 and will not protrude from the counterbore 103. Preferably, the diameters of the through-holes 104 in each of the first connection through-holes 101 and the diameters of the through-holes 104 in each of the second connection through-holes 102 are the same.

[0046] Preferably, as Figure 1 and Figure 2 shown, among the five first connection through-holes 101 distributed in the middle area of the connection block 100, one first connection through-hole 101 is located at the exact center of the connection block 100, and this first connection through-hole 101 is defined as the central first connection through-hole; the remaining four first connection through-holes 101 are distributed on the outer peripheral side of the central first connection through-hole, and the connecting lines of the centers of these four first connection through-holes 101 form a rectangle C2. Therefore, five counterbores 103 are provided in the middle area of the back surface S2 of the connection block 100, and a through-hole 104 is provided in the middle of each of the five counterbores 103.

[0047] Preferably, as Figure 1 and Figure 2As shown in the figure, the counterbores 103 of the three second connection through-holes 102 distributed at the left edge of the connection block 100 communicate with each other and form a straight notch 108 that is distributed at the left edge of the connection block 100 and extends forward and backward. The counterbores 103 of the three second connection through-holes 102 distributed at the right edge of the connection block 100 also communicate with each other and form a straight notch 108 that is distributed at the right edge of the connection block 100 and extends forward and backward. Therefore, the back surface S2 of the connection block 100 is provided with a straight notch 108 that extends forward and backward at each of the left edge and the right edge of the connection block 100. A perforation 104 that forms part of the second connection through-hole 102 is provided in each straight notch 108. At the same time, the depth of the straight notch 108 in the thickness direction of the connection block 100 (i.e., the degree of the counterbore 103 that forms part of the second connection through-hole 102) is greater than the thickness of the head of the placed bolt, and the width of the straight notch 108 in the length direction of the connection block 100 (i.e., the diameter of the counterbore 103 that forms part of the second connection through-hole 102) is greater than the diameter of the head of the placed bolt. One or two of the three perforations 104 in the straight notch 108 are selected for use during use, rather than all three being used simultaneously, to avoid interference between the bolts. In addition, the three perforations 104 in each straight notch 108 are arranged at equal intervals in the front-back direction along the width direction of the connection block 100, and the centers of the three perforations 104 are collinear.

[0048] Further, the distribution mode of the holes in the first connection hole area for fixing the connection block 100 and the positioning device 300 (zero-point positioning disk 301) is as follows: As Figure 2 shown, the second connection hole area includes four threaded holes 105 distributed on the peripheral side of the first connection through-hole 101. The threaded holes 105 are of a blind hole structure and are opened on the back surface S2 of the connection block 100. Therefore, the four threaded holes 105 are also provided in the middle area of the back surface S2 of the connection block 100. The threaded holes 105 are used for thread engagement with screws, and the screws connect the connection block 100 and the positioning device 300. A through-hole for the screw to be screwed into is provided in the positioning device 300. Preferably, the connecting lines of the centers of the four threaded holes 105 form a square C1, and the centers of the five counterbores 103 of the first connection through-hole 101 are all located within the square C1 surrounded by the connecting lines of the centers of the four threaded holes 105. At the same time, the diameters of the four threaded holes 105 in the second connection hole area are the same, but the diameter of the threaded hole 105 is smaller than the diameter of the perforation 104 in the first connection through-hole 101.

[0049] Further, the distribution mode of the holes in the first limit hole area for positioning and limiting when fixing the connection block 100 and the part to be processed 200 is as follows: As Figure 1 and Figure 3As shown, the first limit hole area includes four first pin holes 106 distributed around the first connection through hole 101 and two second pin holes 107 respectively distributed between the first connection through hole 101 and the second connection through hole 102. The first pin holes 106 and the second pin holes 107 are both blind hole structures and are both opened on the front surface S1 of the connection block 100. Therefore, the four first pin holes 106 are provided in the middle area of the front surface S1 of the connection block 100; preferably, the connecting lines of the centers of the four first pin holes 106 form a rhombus C3. Both the first pin holes 106 and the second pin holes 107 are used to accommodate positioning pins. The two ends of the positioning pin are respectively placed in the first pin holes 106 and the second pin holes 107 of the connection block 100, and the other end is placed in the pin hole on the part to be machined 200. The positioning and limiting during the fixed connection between the connection block 100 and the part to be machined 200 are realized by the positioning pin.

[0050] Further, the distribution mode of the holes in the second limit hole area that plays a positioning and limiting role when the connection block 100 and the positioning device 300 are fixed is as follows: As Figure 2 and Figure 3 shown, the second limit hole area includes two third pin holes 109 respectively distributed between the first connection through hole 101 and the second connection through hole 102. The third pin holes 109 are blind hole structures and are opened on the back surface S2 of the connection block 100. Therefore, a third pin hole 109 is provided beside each straight notch 108. The third pin holes 109 are used to accommodate positioning pins. The two ends of the positioning pin are respectively placed in the third pin holes 109 of the connection block 100, and the other end is placed in the pin hole on the positioning device 300. The positioning and limiting during the fixed connection between the connection block 100 and the positioning device 300 are realized by the positioning pin.

[0051] Preferably, the first pin holes 106, the second pin holes 107 and the third pin holes 109 have the same diameter and the same depth. In this embodiment, the depths of the first pin holes 106, the second pin holes 107 and the third pin holes 109 are less than the thickness between the front and back surfaces S2 of the connection block 100, so that the first pin holes 106, the second pin holes 107 and the third pin holes 109 are all blind hole structures. In addition, as Figure 1 and Figure 2 shown, the centers of the two second pin holes 107 provided on the front surface S1 of the connection block 100 and the centers of the two third pin holes 109 provided on the back surface S2 of the connection block 100 are all located on the center line L of the connection block 100 in its width direction, and this center line L extends left and right along the length direction of the connection block 100.

[0052] In addition, the connection block 100 with the above structure is an integral part and is processed by an integral molding method, which is beneficial to improving the structural firmness of the connection block 100 itself.

[0053] In summary, the connecting block 100 involved in the present application has hole structures such as counterbores 103, through holes 104, threaded holes 105, pin holes, and straight slots 108, which can conveniently connect the parts to be machined 200 and the positioning device 300. It is particularly suitable for the connection between small parts to be machined 200 and the zero-point positioning plate 301. Its structure is simple, the connection is reliable, the positioning is accurate, it is convenient for machining and installation, can increase the firmness of the connection, and at the same time can lift the part to be machined 200 to prevent interference between the cutting tool and the positioning device 300 during the machining process.

[0054] Therefore, the present invention effectively overcomes various disadvantages in the prior art and has high industrial utilization value.

[0055] The above embodiments are only illustrative of the principles and effects of the present invention, and are not used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
