Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a quick-release workpiece positioning fixture for induction heaters. Background Technology

[0002] Induction heaters achieve efficient heating through the principle of electromagnetic induction. Their structure is designed around core functions such as power supply, heating coil, cooling, and control, and they are widely used in industrial processing and daily life. In metal workpiece processing, induction heaters can be used for metal heat treatment, such as quenching, annealing, and tempering, which can change the mechanical properties of the metal, improving its hardness, wear resistance, or toughness. This process requires the use of clamps to hold and fix the metal workpiece, ensuring that it can stably penetrate the inner side of the heating coil to achieve an effective heating effect.

[0003] Existing quick-release workpiece positioning fixtures for induction heaters typically use hydraulic devices to clamp and fix metal workpieces for easy assembly and disassembly. However, in actual operation, since the clamped end of the workpiece cannot pass through the heating coil, it is necessary to change the clamping position and perform a secondary heating process after the heated end cools down to achieve a full heating effect, which significantly reduces the convenience of metal workpiece processing. Therefore, this application proposes a quick-release workpiece positioning fixture for induction heaters that allows for rapid change of clamping position. Utility Model Content

[0004] The purpose of this invention is to address the problem in the prior art that requires changing the clamping position of metal workpieces in order to meet the requirements of comprehensive heating treatment of metal workpieces, and to propose a quick-release workpiece positioning fixture for induction heaters that can quickly change the clamping position.

[0005] The technical solution of this utility model: a quick-release workpiece positioning fixture for an induction heater, including a base, on the top of which an induction heater is fixedly mounted, and further including:

[0006] The workpiece clamping base has two parts that are slidably mounted on the top of the base. The workpiece clamping base has a workpiece assembly opening for clamping metal workpieces.

[0007] The L-shaped protective plate is provided in two and fixedly installed at one end of the matching workpiece clamping seat. The two L-shaped protective plates are staggered at one end and located on one side of the heating coil of the induction heater.

[0008] Optionally, a semi-circular support plate is fixedly installed on the bottom wall of the workpiece assembly port, and a semi-circular pressure plate is movably installed inside the workpiece assembly port and above the semi-circular support plate.

[0009] Optionally, a U-shaped heat insulation cover is fixedly installed on the top of the workpiece clamping seat, a cylinder is fixedly installed on the U-shaped heat insulation cover, a connecting rod is fixedly installed on the output end of the cylinder, and the bottom end of the connecting rod is inserted into the workpiece assembly opening and fixedly connected to the semi-arc pressure plate.

[0010] Optionally, one end of the L-shaped protective plate is fixedly connected to the workpiece clamping seat and the U-shaped heat insulation cover, and a handle is fixedly installed on each of the L-shaped protective plates.

[0011] Optionally, two slide rails are fixedly installed on the top of the base, and the workpiece clamping seat is slidably installed on the top of the two slide rails.

[0012] Optionally, a T-shaped groove is chiseled at the top of the slide rail, and two T-shaped sliders are fixedly installed on the lower surface of the workpiece clamping seat. The T-shaped sliders are embedded in matching T-shaped grooves and slidably connected to them.

[0013] Compared with the prior art, this application includes at least one of the following beneficial technical effects: the cylinder drives the semi-circular pressure plate to move downward, which facilitates the quick clamping of the metal workpiece on the workpiece clamping seat, achieving the effect of quick assembly and disassembly.

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

[0028] like Figure 1 and Figure 2 As shown, the quick-release workpiece positioning fixture for the induction heater proposed in this utility model includes a base 1, an induction heater 2 fixedly mounted on the top of the base 1, and a heating coil fixedly mounted on one end of the induction heater 2. The heating coil is electrically connected to the induction coil inside the induction heater 2. An alternating magnetic field is generated through the induction coil. When a metal workpiece passes through the heating coil, an induced electromotive force and eddy current are generated inside the metal workpiece, achieving the purpose of heating. Two symmetrically arranged workpiece clamping seats 7 are slidably mounted on the top of the base 1. The workpiece clamping seats 7 have workpiece assembly openings 71, through which the metal workpiece is inserted to easily fix it in the workpiece clamp. On the holding base 7, two workpiece clamping bases 7 can alternately clamp and fix the two ends of the metal workpiece that are far apart, avoiding the inability to effectively heat the clamped part of the metal workpiece due to single-end fixing, eliminating the need for secondary heating treatment and improving the convenience of metal workpiece processing; one end of the aforementioned workpiece clamping base 7 is fixedly installed with an L-shaped protective plate 6, and the two L-shaped protective plates 6 are staggered at the ends that are close to each other. The aforementioned heating coil is located between the L-shaped protective plate 6 and the induction heater 2. When the operator pushes the workpiece clamping base 7 to slide, the L-shaped protective plate 6 can prevent the hand from accidentally touching the heating coil and causing burns, thus improving the safety of processing operations.

[0029] like Figure 1 and Figure 2 As shown, in order to improve the firmness of clamping and fixing the metal workpiece, a semi-circular support plate 73 is fixedly installed on the bottom wall of the workpiece assembly port 71. A semi-circular pressure plate 72 that can be raised and lowered is provided inside the workpiece assembly port 71 and above the semi-circular support plate 73. The metal workpiece can be pressed and fixed on the semi-circular support plate 73 by the semi-circular pressure plate 72, which facilitates the firm clamping of the workpiece.

[0030] Furthermore, in order to achieve the purpose of rapid assembly and disassembly of metal workpieces, a U-shaped heat insulation cover 3 is fixedly installed on the top of the workpiece clamping seat 7. A cylinder 4 is fixedly installed on the U-shaped heat insulation cover 3. A connecting rod 41 is fixedly installed on the output end of the cylinder 4. The bottom end of the connecting rod 41 passes into the workpiece assembly port 71 and is fixedly connected to the semi-arc pressure plate 72. The cylinder 4 drives the semi-arc pressure plate 72 to move up and down. When the semi-arc pressure plate 72 moves downward, it can quickly clamp and fix the metal workpiece. When the semi-arc pressure plate 72 moves upward, it can quickly remove the metal workpiece from the workpiece clamping seat 7.

[0031] Secondly, the opening on one side of the U-shaped heat shield 3 is located away from the heating coil, which not only facilitates the installation of the cylinder 4, but also provides heat insulation for the cylinder 4.

[0032] like Figure 1 and Figure 2 As shown, in order to facilitate the lateral pushing of the workpiece clamping seat 7, two parallel slide rails 5 are fixedly installed on the top of the base 1. The workpiece clamping seat 7 is slidably installed on the top of the two slide rails 5. When the workpiece clamping seat 7 is pushed to move towards the heating coil side, the slide rails 5 can ensure that the workpiece clamping seat 7 slides stably laterally, thus improving its stability during the pushing.

[0033] Secondly, a T-shaped groove 51 is cut at the top of the slide rail 5, and two T-shaped sliders 74 are fixedly installed on the lower surface of the workpiece clamping seat 7. The T-shaped sliders 74 are inserted into the matching T-shaped grooves 51 and slidably connected with them, effectively preventing the workpiece clamping seat 7 from falling off the slide rail 5.

[0034] like Figure 3 and Figure 4 As shown, when it is necessary to clamp and fix the metal plate 8, first pass one end of the metal plate 8 through the workpiece assembly port 71. After one end of the metal plate 8 overlaps the top of the semi-circular support plate 73, the cylinder 4 drives the semi-circular pressure plate 72 to move downward. When the lower surface of the semi-circular pressure plate 72 is in close contact with the metal plate 8, the metal plate 8 can be firmly clamped on the top of the semi-circular support plate 73. When it is necessary to clamp and fix the metal rod 9, first pass one end of the metal rod 9 through the workpiece assembly port 71. After the outer wall of one end of the metal rod 9 is in close contact with the inner wall of the semi-circular support plate 73, the cylinder 4 drives the semi-circular pressure plate 72 to move downward. When the inner wall of the semi-circular pressure plate 72 is in close contact with the outer wall of the metal rod 9, the metal rod 9 can be firmly clamped and fixed. This allows the fixture to meet the clamping and fixing needs of plate-type metal workpieces and rod-type metal workpieces, effectively improving its applicability.

[0035] In this embodiment, one end of the metal workpiece is first passed through the workpiece assembly port 71. When one end of the metal workpiece is inside the workpiece assembly port 71, the cylinder 4 drives the semi-circular pressure plate 72 to move downward, which facilitates clamping and fixing the metal workpiece on the top of the semi-circular pressure plate 72. When the cylinder 4 drives the semi-circular pressure plate 72 to move upward, the clamping and fixing of the metal workpiece can be released, achieving the purpose of quick assembly and disassembly of the metal workpiece. After the metal workpiece is fixed, the operator holds the handle 61 and pushes the workpiece clamping seat 7 holding the metal workpiece to move laterally, ensuring that the end of the metal workpiece away from the clamping part can pass through the heating coil. During this process, the heating coil is energized by the induction heater 2. The induction coil installed inside the induction heater 2 generates an alternating magnetic field. When the metal workpiece passes through the heating coil, an induced electromotive force and eddy current are generated inside the metal workpiece, achieving the purpose of heating. During the process of the operator pushing the workpiece clamping seat 7 to move laterally, the heating coil is always located inside the two L-shaped protective plates 6, which can prevent the hand from accidentally touching the heating coil and causing burns, thus improving the safety factor of the heating operation.

[0036] After the end of the metal workpiece away from the clamping part has been heated, another workpiece clamping seat 7 is pushed towards the heating coil. When the end of the metal workpiece away from the clamping part passes through the workpiece assembly opening 71 cut into the workpiece clamping seat 7, the corresponding cylinder 4 drives the semi-circular pressure plate 72 to move downward, which facilitates clamping and fixing the heated end of the metal workpiece. The workpiece clamping seat 7 is pushed again and moved away from the heating coil. When the unheated end of the metal workpiece passes through the heating coil, the full heating of the metal workpiece can be completed. There is no need to wait for the metal workpiece to cool down and change the clamping part, which saves the time required for secondary heating and effectively improves the convenience of metal workpiece processing.

[0037] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
