[0002] With the rapid advancement of technology, modern electronic devices are increasingly demanding higher heat dissipation performance. In electronics, mechanical equipment, and other fields, the cooling speed of control panels is particularly important. Currently, control panels are typically cooled using heat sinks in conjunction with refrigerant pipes. These heat sinks are fixedly connected to the control panels. These heat sinks, cut from extruded aluminum profiles, typically require multiple mounting holes.

[0003] Holes are usually drilled in the clamped heat sink using a machining center, and a fixture is usually used to clamp and position the two sides of the heat sink. The existing heat sink processing and clamping operation method is to place the heat sink on the fixture, and then operate the cylinder to press and clamp the two sides of the fixture to clamp the heat sink. One fixture clamps one or two heat sinks. This clamping method cannot position the heat sink and the number of pieces that can be processed at one time is very small, resulting in low heat sink processing efficiency. Therefore, it is particularly important to develop a fixture technology that can quickly clamp the heat sink and improve processing efficiency. Utility Model Content

[0023] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0024] The following combination Figures 1 to 5 , describing a fast clamping heat sink processing fixture according to an embodiment of the present utility model.

[0025] A fast-clamping heat sink processing fixture includes a base plate 1, an auxiliary clamping strip 2, a top holding piece 3 and a positioning piece 4; the top holding piece 3 and the auxiliary clamping strip 2 are installed on the top of the base plate 1, and the side wall of the auxiliary clamping strip 2 is installed with the positioning piece 4. The position of the top holding piece 3 corresponds to the side wall of the auxiliary clamping strip 2 on which the positioning piece 4 is installed. The heat sink is placed between the top holding piece 3 and the auxiliary clamping strip 2, and the top holding piece 3 and the auxiliary clamping strip 2 cooperate to clamp the left and right sides of the heat sink; the front and back sides of a heat sink are both installed with positioning pieces 4, and the distance between the two positioning pieces 4 can be set according to the width of the heat sink. The heat sink is first placed between the two positioning pieces 4, and then the top holding piece 3 is used to hold the heat sink.

[0026] A fast-clamping heat sink processing fixture is used to clamp a heat sink. The distance between the two positioning members 4 can be adjusted according to the width of the clamped heat sink, and heat sinks of different sizes can be positioned. When the heat sink is clamped for processing, the heat sink is first placed between the two positioning members 4. The position between the two positioning members 4 is the position where the top holding member 3 holds the heat sink, which can accurately clamp the heat sink and prevent the heat sink from shaking during the clamping process. After the heat sink is located between the two positioning members 4, the top holding member 3 starts to hold the heat sink. The left and right sides of the heat sink are now held by the top holding member 3 and the auxiliary clamp 2, and the heat sink is fixedly clamped for processing. The auxiliary clamp 2 and the top holding member 3 are used to clamp the heat sink, which can be quickly clamped and disassembled. When clamping or disassembling the heat sink, the top holding member 3 only needs to be pushed to hold or retracted to disassemble. The operation is simple and convenient, and can improve processing efficiency.

[0027] The auxiliary clamping strip 2 can be equipped with multiple positioning members 4 on the side wall according to its length, and multiple supporting members 3 can be installed at the positions of the multiple positioning members 4, so as to clamp multiple heat sinks at the same time, further improving the processing efficiency.

[0028] Specifically, the positioning member 4 includes a positioning bar 41 and a fixing bolt 42. A slot for mounting the positioning member 4 is provided on the sidewall of the auxiliary clamping bar 2. A fixing slot is provided at the top of the auxiliary clamping bar 2, which is connected to the slot and located directly above the slot. A fixing hole is provided at the top of the positioning bar 41, located at one end of the slot. A fixing bolt 42 is inserted into the fixing hole and into the fixing slot. The upper end of the fixing bolt 42 is held against the top of the auxiliary clamping bar 2, while the lower end of the fixing bolt 42 is fixedly connected to the positioning bar 41, securing one end of the positioning bar 41 against the top of the slot. The positioning bar 41 can be moved within the slot, facilitating adjustment of the distance between the two positioning bars 41 for positioning the heat sink. After the two positioning bars are properly positioned, the fixing bolt 42 is twisted. After the lower end of the fixing bolt 42 is inserted into the fixing hole, the fixing bolt 42 is continuously twisted until the positioning bar 41 is tightly attached to the top sidewall of the slot, securing the positioning bar 41. The positioning bar 41 can be secured solely by the fixing bolt 42, resulting in low cost, ease of manufacture, and simplified operation, which speeds up installation.

[0029] Specifically, one chute is equipped with two positioning bars 41. The length of the chute is greater than the length of the heat sink. The two positioning bars 41 are located on the front and back sides of the heat sink, respectively. This facilitates the placement of the heat sink between the two positioning bars 41. The two positioning bars 41 can position heat sinks of different widths, providing strong versatility.

[0030] To further illustrate, the side of the positioning bar 41 closest to the heat sink is configured as an inclined surface, and the inclined surfaces of the positioning bars 41 on both sides of the heat sink are shaped like an inverted figure eight. Because the inclined surfaces of the positioning bars 41 on both sides of the heat sink are in this inverted figure eight shape, the heat sink can be quickly inserted. The inclined sides of the positioning bar 41 facilitate guiding the heat sink, allowing the heat sink to slide along the inclined surface at the top of the positioning bar 41 to the bottom for positioning.

[0031] To further illustrate, the positioning bar 41 is T-shaped, with the higher end of the positioning bar 41 located inside the chute, so that the positioning bar 41 is confined in the chute and is not easy to fall off. When the positioning bar 41 is subjected to external thrust, the chute can support the positioning bar 41 to prevent the chute from shaking.

[0032] Specifically, auxiliary clamping strips 2 are installed on both sides of the top holding member 3. Heat sinks can be placed on both sides of the top holding member 3. The top holding member 3 can simultaneously hold the heat sinks on both sides. It can clamp multiple heat sinks at one time, improving processing efficiency.

[0033] Specifically, the supporting member 3 includes a supporting block 31, a movable block 32, and a cylinder 33. Supporting blocks 31 are mounted on both sides of the movable block 32. The lower ends of the left and right sides of the movable block 32 are tilted inward, and the lower end of the supporting block 31 on the side closest to the movable block 32 is tilted toward the movable block 32. The supporting block 31 is slidably mounted on the top of the base plate 1. The driving end of the cylinder 33 is connected to the movable block 32. The cylinder 33 pushes the movable block 32 up and down, causing the movable block 32 to push the supporting block 31 left and right to support the heat sink. The heat sink can be clamped using only the supporting blocks 31, movable block 32, and cylinder 33. The supporting blocks 31, movable block 32, and cylinder 33 are low in manufacturing cost, easy to maintain, and simple to operate. The inclined surface of the movable block 32 is provided with a protrusion, and the inclined surface of the supporting block 31 is provided with a groove. The protrusion slides into the groove. The groove ensures that the supporting block 31 and the movable block 32 can only slide up and down, thus limiting the position and helping the supporting block 31 to support the heat sink. In another embodiment, the bottom ends of multiple movable blocks 32 are fixed to a drive rod. The bottom of this drive rod is connected to the drive end of the cylinder 33. Therefore, a single cylinder can drive the synchronous movement of multiple movable blocks 32.

[0034] Specifically, the substrate 1 located directly below the supporting block 31 is provided with a supporting cavity 11, and a connecting block 34 protrudes from the bottom of the supporting block 31. The connecting block 34 is installed in the supporting cavity 11 and slides in the supporting cavity 11, and the vertical surface of the connecting block 34 is T-shaped; an elastic member is installed inside the supporting cavity 11, and the elastic member supports the connecting block 34 to keep the supporting block 31 in contact with the movable block 32. The supporting block 31 is not easily moved forward or backward during the left and right movement through the connecting block 34, which facilitates the supporting block 31 to support the heat sink. When the movable block 32 moves upward, the elastic member can support the supporting block 31 to move the position and release the supporting heat sink, making it easier to move the position of the supporting block 31. The elastic member can be a spring, which has low cost and good elasticity.

[0035] Further explanation, if both sides of the auxiliary clamping strip 2 are provided with supporting members 3, both sides of the auxiliary clamping strip 2 are provided with positioning members 4. Multiple heat sinks can be clamped at the same time, thereby improving processing efficiency.

[0036] Specifically, if the front and rear sides of the support member 3 are provided with limit blocks 6, the side surfaces of the limit blocks 6 are in contact with the support member 3, and mounting blocks 7 are provided on both sides of the bottom of the base plate 1, the base plate 1 can be fixed to the machine tool by the mounting blocks 7.
