Description

Technical Field

[0001] This invention relates to the field of tooling and fixture technology, and in particular to a tooling for cutting and clamping sealing strips. Background Technology

[0002] A scroll compressor is a positive displacement compressor. The compression component consists of a moving scroll and a stationary scroll. The high-speed rotation of the moving scroll compresses the gas. The moving and stationary scrolls are connected by an eccentric shaft. To ensure the sealing of the compression chamber, a sealing groove is provided on the end face of the scroll band of the moving scroll. A sealing strip is installed within the sealing groove to ensure the sealing of the compression chamber. However, there is relative movement between the end face of the sealing strip and the stationary scroll. The sealing strip must be positioned to prevent it from moving within the sealing groove. Currently, a V-shaped boss is usually provided within the sealing groove, and then retaining clips are provided on both sides of the sealing strip to limit its movement, thus positioning the sealing strip within the sealing groove and preventing movement. However, the sealing strips purchased are usually in rolls, requiring subsequent cutting and cutting of retaining clips on both sides. Currently, there is no dedicated equipment for cutting grooves in the sealing strips. Summary of the Invention

[0003] In order to solve the above-mentioned problems existing in the sealing strip grooving of the prior art, the present invention provides a sealing strip grooving device that is stable in positioning and easy to use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A sealing strip cutting tool includes a frame and a base plate fixed on the frame. A positioning plate is fixed on the top surface of the base plate, and the top surface of the positioning plate has a positioning groove. A guide groove is provided on one side of the positioning groove on the positioning plate, which communicates with the side of the positioning groove. A pressure plate assembly is provided in the guide groove, and the pressure plate assembly is slidably connected to the guide groove. A tool guide plate is provided on the top surface of the positioning plate. A cylinder seat is fixed on one side of the positioning plate on the base plate, and a cylinder is fixed on the cylinder seat. A connecting seat is fixed on the shaft end of the cylinder, and a tool holder is fixed on the connecting seat. Two blades distributed on both sides of the positioning groove are fixed on the tool holder. The tool guide plate has guide channels corresponding to the blades, and the positioning plate has clearance grooves corresponding to the blades. A linkage mechanism for driving the pressure plate assembly to slide along the guide groove is provided between the connecting seat and the pressure plate assembly. The sealing strip is inserted into the positioning groove from one end. The cylinder shaft extends and drives the blade to descend. Through the linkage mechanism, the pressure plate assembly presses one side of the sealing strip. When the blade passes the sealing strip, it cuts the sealing strip, making two V-shaped notches on both sides of the sealing strip. After cutting, the cylinder shaft retracts, the cut sealing strip is taken out, and the sealing strip to be cut is installed. This tooling can quickly achieve the cutting of the sealing strip notches, and the sealing strip is positioned stably with high notch accuracy.

[0006] Preferably, the linkage mechanism includes a connecting plate fixed to the connecting seat. One end of the connecting plate is bent downwards to form a vertical plate, and the lower end of the vertical plate is bent outwards to form an inclined driving plate. A long slot is provided at the outer end of the pressure plate assembly corresponding to the driving plate, and the driving plate passes through the long slot. When the cylinder shaft extends, the driving plate moves downwards, and the inner inclined surface of the driving plate pushes the pressure plate assembly inwards to press the sealing strip. When the cylinder shaft retracts, the driving plate moves upwards, and the outer inclined surface of the driving plate pulls the pressure plate assembly outwards to release the sealing strip. This linkage mechanism achieves the linkage between the pressure plate assembly and the cylinder shaft, eliminating the need for a separate driving mechanism for the pressure plate assembly, resulting in a more compact and stable overall structure.

[0007] Preferably, the pressure plate assembly includes a front pressure plate and a rear push plate. The front pressure plate is slidably connected to both sides of the guide groove. The inner end of the front pressure plate has a clearance groove, and the outer end of the front pressure plate has a notch. The bottom ends of the notch have limiting grooves. The inner end of the rear push plate extends into the notch, and the inner ends of the rear push plate have limiting bosses that mate with the limiting grooves. The elongated slot is located at the outer end of the rear push plate, and an elastic pad is provided between the inner end of the rear push plate and the bottom of the notch. The front pressure plate presses against the side of the sealing strip to position the sealing strip. Under the action of the drive plate, the rear push plate pushes the front pressure plate forward or backward. The elastic pad between the rear push plate and the front pressure plate allows the front pressure plate to elastically press the sealing strip, preventing damage to the sealing strip.

[0008] Preferably, a baffle is fixed to one end of the positioning groove on the substrate, and the baffle is provided with an adjusting bolt that extends into the positioning groove. The adjusting bolt can adjust the depth of the bolt extending into the positioning groove, thereby adjusting the position of the sealing strip cutout.

[0009] Preferably, the tool guide plate is provided with a pin hole, and the base plate is provided with a positioning pin that mates with the pin hole. The mating of the pin hole and the positioning pin makes the connection between the tool guide plate and the base plate more accurate.

[0010] Preferably, the side of the frame is provided with a manual directional valve for controlling the extension and retraction of the cylinder shaft.

[0011] Therefore, the present invention has the advantages of stable positioning, convenient use, and high sealing strip clamping accuracy. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 The sealing strip cutting and clamping fixture shown includes a frame 1, a base plate 2 fixed on the frame, and a positioning plate 3 fixed on the top surface of the base plate 2. Figure 8As shown, the top surface of the positioning plate 3 is provided with a positioning groove 30. A guide groove 31, communicating with the side of the positioning groove, is provided on one side of the positioning plate 3. A pressure plate assembly 4 is provided within the guide groove 31, and the pressure plate assembly 4 is slidably connected to the guide groove 31. A tool guide plate 5 is provided on the top surface of the positioning plate 3, and a pin hole 51 is provided on the tool guide plate 5. A positioning pin 52, cooperating with the pin hole, is provided on the base plate 2. A cylinder seat 6 is fixed on one side of the positioning plate on the base plate 2, and a cylinder 7 is fixed on the cylinder seat 6. A connecting seat 8 is fixed to the shaft end of the cylinder 7, and a tool holder 9 is fixed on the connecting seat. Two blades 10 distributed on both sides of the positioning groove are fixed on the tool holder. The tool guide plate 5 is provided with guide channels 50 corresponding to each blade, and the positioning plate 3 is provided with clearance grooves 32 corresponding to each blade. A linkage mechanism 11 for driving the pressure plate assembly to slide along the guide groove is provided between the connecting seat 8 and the pressure plate assembly 4. A manual reversing valve 14 for controlling the extension and retraction of the cylinder shaft is provided on the side of the frame 1.

[0024] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the linkage mechanism 11 includes a connecting plate 110 fixed to the connecting seat 8. One end of the connecting plate 110 is bent downward to form a vertical plate 111, and the lower end of the vertical plate 111 is bent outward to form an inclined drive plate 112. The outer end of the pressure plate assembly 4 is provided with an elongated slot 46 corresponding to the drive plate, and the drive plate passes through the elongated slot. When the cylinder shaft extends, the drive plate moves downward, and the inner inclined surface on the drive plate pushes the pressure plate assembly to move inward to press the sealing strip. When the cylinder shaft retracts, the drive plate moves upward, and the outer inclined surface on the drive plate pulls the pressure plate assembly to move outward to loosen the sealing strip.

[0025] like Figure 7 and Figure 8 As shown, the pressure plate assembly 4 includes a front pressure plate 40 and a rear push plate 41. The front pressure plate 40 is slidably connected to both sides of the guide groove 31. The inner end of the front pressure plate 40 is provided with a relief groove 42, and the outer end of the front pressure plate 40 is provided with a notch 43. The bottom ends of the notch 43 are provided with limiting grooves 44. The inner end of the rear push plate 41 extends into the notch. The inner ends of the rear push plate 41 are provided with limiting bosses 45 that cooperate with the limiting grooves 44. The elongated slot 46 is provided at the outer end of the rear push plate. An elastic pad 47 is provided between the inner end of the rear push plate and the bottom of the notch. A baffle 12 is fixed on one end of the positioning groove on the base plate 2. The baffle is provided with an adjusting bolt 13 that extends into the positioning groove.

[0026] Referring to the accompanying drawings, the principle of the present invention is as follows: Figure 1 and Figure 6As shown, the sealing strip 15 is inserted into the positioning groove from one end, and the insertion depth is adjusted by the adjusting bolt. The cylinder shaft extends via the manual reversing valve 14, causing the connecting seat to move the cutter holder and blade downwards. The connecting plate moves the drive plate downwards synchronously. When the drive plate moves downwards, it pushes the pressure plate assembly inwards to elastically press the side of the sealing strip, completely positioning it. The two blades cut the sealing strip from both sides, creating a clamping action. The state of the sealing strip 15 after the clamping action is as follows: Figure 9 As shown, the cylinder shaft retracts again via the manual reversing valve, causing the connecting seat to lift the blade and connecting plate. As the drive plate rises, the outer inclined surface of the drive plate pulls the pressure plate assembly outwards to loosen the sealing strip after the cutting jaws are opened. The sealing strip is then removed, and a new sealing strip is installed. This invention offers the advantages of stable positioning, ease of use, and high precision in sealing strip clamping.

[0027] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
