Description

Technical Field

[0001] The present application belongs to the technical field of clamping small parts, and in particular to a clamp used in the manufacturing process of a ceramic splitter. Background Art

[0002] In an aluminum wire bonding splitter that is easy to clean automatically and has a publication number of CN218309621U, the splitter is clamped to include a low-position part and several groups of movable high-position blocks arranged side by side. The bottom end of the low-position part is provided with several low-position welding grooves, and the cross-section of the low-position welding groove is rectangular or semicircular. The movable high-position block is provided with a high-position threading groove that can be opened. The movable high-position block is formed by docking two blocks, and the top surface of the block is against the outer side surface of the splitter seat. A screw rod groove is provided on the upper part of each block, and a semicircular through groove is provided on the lower part. The screw rod grooves of the two blocks rotate in opposite directions, and the semicircular through grooves of the two blocks are docked to form a high-position threading groove. It mainly uses a clamping structure to fix the splitter. This clamping structure only acts on a part of the splitter to fix the splitter, resulting in unstable clamping and excessive local force, which causes the splitter to be damaged.

[0003] At the same time, in a wire bonding splitter cleaning and drying device with publication number CN214865748U, the splitter clamping device includes a clamping plate, a clamping block, a tension bolt, a bearing, a first coupling, a first stepper motor, a first stepper motor bracket and a bearing bracket. A plurality of grooves are provided on the clamping plate, which cooperate with the grooves on the clamping block to clamp the splitter and are fixed with tension bolts.

[0004] From the above two comparative documents, it can be seen that in the prior art, general technicians use a clamping method to fix the splitting knife, but the clamping method will cause the above-mentioned disadvantages, and the splitting knife is too small to be clamped directly. Utility Model Content

[0005] The utility model aims to solve the existing problems and provides a convenient fixation method, which only requires inserting the splitting knife into the hole of the fixed base, and the splitting knife is fixed by filling the expansion structure in the control area at the bottom of the splitting knife.

[0006] In order to achieve the above technical objectives, the following technical solutions are provided: a fixture for use in the production process of a ceramic splitting knife, comprising a splitting knife base, which is a square fixed plate and has a plurality of through-holes in the thickness direction, an air core is embedded in one end of the hole, and the air core has a sealed tip portion, which extends into the tail end hole of the splitting knife to fix the splitting knife.

[0007] In an embodiment, the air core includes a cylindrical core seat, to which a conical tip portion is integrally connected, wherein the cylindrical core seat has a hollow connecting channel, and the tip portion has a cavity, and the connecting channel connects the outside of the splitting knife base with the cavity to inflate and deflate the cavity to achieve expansion and contraction of the cavity, and the splitting knife is fixed by the expansion and contraction of the cavity.

[0008] In an embodiment, the clamping holes are arranged in an array on the riving knife base, and the sides of the array are parallel to the side edges of the riving knife base.

[0009] In an implementable embodiment, an outer edge is provided on the length side of the splitting knife base, at least two fixing holes are provided on the outer edge, pillars are fixed on the fixing holes by coaxial bolts, and the splitting knife base can be fixed on the pillars.

[0010] In an embodiment, when there are at least three riving knife bases, a screw rod with threads at both ends is arranged in the fixing hole of the riving knife base located in the middle; the riving knife base is fixed in the middle of the screw rod, and pillars are fixed at both ends.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] Compared with the snap-fit ​​structure, the insert-disc fixing structure of the present application can store a larger number of items and has a stable clamping, thus protecting the entire riving knife and preventing damage to the side wall of the riving knife.

[0013] The tail of the splitting knife is fixed by the expansion and contraction of the gas core, which makes the fixing operation simple and ensures the safety of the fixing operation; the tip can be inserted into the splitting knife hole and expands in the splitting knife hole to achieve a tight fixation between the splitting knife and the splitting knife base, preventing the splitting knife from moving in the axial direction of the clamping hole.

[0014] The connection design of multiple riving knife bases allows for the storage of more riving knives and the stacking of riving knife tips without damaging them. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] like Figure 1 and Figure 2 The first embodiment shown is a fixture used in the production process of a ceramic splitting knife, including a splitting knife base 1, which is a square fixed plate and has a plurality of through-holes 2 in the thickness direction. An air core 3 is embedded in one end of the hole 2, and one end of the air core 3 can be extended into the tail end hole of the splitting knife to fix the splitting knife.

[0025] like Figure 3 As shown, in this embodiment, the air core 3 is used as an expansion mechanism to achieve the close fit between the tail of the splitting knife and the splitting knife base 1 so as to achieve fixation. The air core 3 includes a cylindrical core seat 32, and a conical tip portion 31 is integrally connected to the cylindrical core seat 32, wherein a hollow connecting channel 33 is provided in the cylindrical core seat 32, and a cavity 34 is provided in the tip portion 31, and the connecting channel 33 connects the outside of the splitting knife base 1 with the cavity 34 to inflate and deflate the cavity 34 to achieve expansion and contraction of the cavity 34, and the splitting knife is fixed by the expansion and contraction of the cavity 34.

[0026] In this embodiment, the air core 3 is made of rubber material, and its tip 31 is a conical rubber airbag with a thin outer wall, and the conical rubber airbag is where the cavity 34 is located. Its cylindrical core seat 32 is a cylindrical hard rubber ring with a thick outer wall, and a connecting channel 33 with a smaller diameter is in the middle.

[0027] The air core 3 is embedded in the clamping hole 2 of the splitting knife base 1 before being inserted into the splitting knife. After being inserted into the splitting knife base 1, the air core 3 can be used repeatedly without being taken out again.

[0028] like Figure 4 As shown, when in use, after the splitting knife base 1 with the air core 3 is inserted, it is placed in a placement frame, and the surrounding of the placement frame is in close contact with the splitting knife base 1. The placement frame of this embodiment is hollow at the bottom and is connected to an air pump through a pipeline. After the splitting knife base 1 is embedded in the placement frame, the air pump starts to work and extracts the air in the cavity 34, and the tip 31 is in a needle shape. At this time, the operator starts to quickly insert the tail of the splitting knife into the clamping hole 2, and waits for the needle-shaped tip 31 to extend into the tail of the splitting knife. After all the clamping holes 2 are fully inserted into the splitting knife, the air pump stops working and reversely transports part of the gas to achieve the resetting of the cavity 34, so that the tip 31 has a radial force on the inner wall of the splitting knife to fix the splitting knife.

[0029] In this embodiment, the clamping holes 2 are arranged in an array on the riving knife base 1 , and the sides of the array are parallel to the side of the riving knife base 1 .

The fixing holes are fixed with pillars by coaxial bolts, and the splitting knife base 1 can be fixed on the pillars. Preferably, when three clamps are stacked, that is, when there are three splitting knife bases 1, a screw with threads at both ends is provided in the fixing hole of the splitting knife base 1 located in the middle; the splitting knife base 1 is fixed in the middle of the screw, and pillars are fixed at both ends.

[0031] Embodiment 3. In embodiment 1, the gas core 3 is integrally formed, and all cylindrical core seats 32 are fixed on a rubber base, which is convenient for the production and storage of the gas core 3, and also convenient for embedding the gas core 3 on the splitting knife base 1. It is only necessary to align the tip 31 of the gas core 3 with the card hole 2 on the splitting knife base 1, and then press it.
