Description

Technical Field

[0001] This utility model relates to the field of sealing strip processing technology, specifically a door guide groove extraction tooling. Background Technology

[0002] The sealing strip processing industry focuses on producing rubber or plastic seals for leak prevention, sound insulation, and vibration damping. These seals are widely used in the automotive, construction, and home appliance industries. Sealing strips can be filled into door guide grooves to achieve leak prevention and sound insulation effects. Sealing strip processing requires the use of sprue-making tools, which are used to trim the sprue of automotive sealing strips, greatly improving product production efficiency and quality stability.

[0003] Currently, there are still some shortcomings in the tooling for edge trimming. For example, after the edge trimming is completed, the operator needs to manually replace the new sealing strip, which wastes time and manpower and affects the trimming efficiency of the sealing parts.

[0004] To overcome the problem of low trimming efficiency, a prior art Chinese patent (publication number: CN213054938U) discloses a trimming tool for processing automotive sealing strips. By rotating the second rotary handle, the second threaded rod is driven to rotate, and the rotation of the second threaded rod drives the clamping plate to move, which can adjust the position of the blade to achieve the effect of trimming different sealing strips. The first rubber pad and the second rubber pad can prevent scratches on the sealing strip when clamping it, and the first rubber pad and the second rubber pad can clamp the sealing strip more securely.

[0005] However, the currently used stripping tool still has some shortcomings. The above document adjusts the position of the blade to achieve different strip trimming effects, but the trimming length is not accurate enough and needs to be adjusted slowly, which will affect the stripping efficiency of the tool and may also affect the compatibility of the strip, making it unusable. Therefore, the existing structure needs to be improved. Utility Model Content

[0006] The purpose of this utility model is to provide a door guide groove stripping tooling to solve the problems mentioned in the background art, such as the inconvenience of measuring the stripping length of the sealing strip, the impact on the sealing strip fit, and the possible displacement of the limiting block after being squeezed by the sealing strip.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a door guide groove extraction tooling, comprising a housing, wherein a machined part is mounted on the bottom surface inside the housing.

[0008] The inside of the housing is provided with a movable groove on the side near the workpiece. A rotating wheel is installed inside the movable groove. A sliding block slides through the movable groove away from the rotating wheel. A measuring mechanism to improve the accuracy of the stripping is provided inside the movable groove.

[0009] The side of the movable groove is provided with a through groove, and a squeezing mechanism is provided inside the through groove to improve the stability of the measuring mechanism.

[0010] Furthermore, the measuring mechanism includes a thickened ruler, one end of which is connected to the side of the sliding block, and the thickened ruler is rotated through the surface of the rotating wheel. A strong spring is connected between the movable groove and the sliding block.

[0011] Furthermore, a limit block is fixed at the end of the sliding block, and external blocks are symmetrically fixed at the front of the housing. A winding column is rotatably connected between the external blocks, and a ratchet is fixed at the end of the winding column.

[0012] Furthermore, the ratchet rotates through the inside of the outer block, and the other end of the thickened ruler is wound around the surface of the winding column. The surface of the thickened ruler is also provided with scale lines.

[0013] Furthermore, the external block has a telescopic groove on its side near the ratchet, and a telescopic block slides through the inside of the telescopic groove. A spring connects the telescopic block and the telescopic groove.

[0014] Furthermore, a positioning block is fixed to the end of the telescopic block, and the positioning block is attached to the side of the ratchet teeth, and the positioning block can position the ratchet.

[0015] Furthermore, the extrusion mechanism includes a fixing block, which is fixed to the side of the sliding block and slides through the through groove. An extrusion block is rotatably slidable on the surface of the fixing block, and a protrusion block is fixed at the end of the fixing block away from the sliding block.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This door guide groove extraction tooling uses a limit block with a strong spring for positioning. The position of the limit block can be determined by the value of the scale on the thickened ruler, thus determining the length of the sealing strip insertion. After the sealing strip is inserted, it can be precisely extracted. The squeezing of the extrusion block will drive the sliding block to squeeze the inner wall of the movable groove. After the sliding block is squeezed and positioned, it can drive the limit block to be positioned. The strong spring and the extrusion block can achieve dual positioning of the sliding block.

[0018] 2. Equipped with a rotating wheel, the direction of the thickened measuring tape can be changed by rotating the wheel, so that when the thickened measuring tape is pulled for a long time, the limit block will move away from the workpiece. The position of the limit block can be precisely adjusted according to the value of the thickened measuring tape.

[0019] 3. Equipped with a ratchet, the thickened tape can be positioned by the ratchet and the positioning block to prevent the thickened tape from being pulled back by the strong spring, thus realizing the self-locking function of the winding column and improving the convenience of adjusting the length of the thickened tape.

[0020] 4. A protruding block is provided, which can squeeze the extrusion block, thereby squeezing the housing shell, so that the sliding block can be positioned inside the movable groove, improving the stability of the sliding block. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] When processing the sealing strip, holes are first drilled. After drilling, the sealing strip is placed into the corresponding cutting port of the strip cutting machine. According to the usage requirements, part of the strip is cut off.

[0032] Example 1, such as Figures 1-8 The present invention provides the following technical solution to address the problem that the stripping tooling is inconvenient for measuring the stripping length of the sealing strip, thus affecting the sealing strip's fit. A measuring mechanism is disclosed, comprising a housing 1, with a workpiece 2 mounted on the bottom surface inside the housing 1. A movable groove 101 is provided on the side of the housing 1 near the workpiece 2. A rotating wheel 102 is installed inside the movable groove 101. A sliding block 103 slides through the movable groove 101 away from the rotating wheel 102. A measuring mechanism for improving stripping accuracy is provided inside the movable groove 101. The measuring mechanism includes a thickened ruler 104, one end of which is connected to the side of the sliding block 103. The thickened ruler 104 is rotated via the surface of the rotating wheel 102. A strong spring connects the movable groove 101 and the sliding block 103. A spring is used to fix a limiting block 105 at the end of the sliding block 103. External blocks 106 are symmetrically fixed at the front of the housing 1. A winding column 107 is rotatably connected between the external blocks 106. A ratchet 108 is fixed at the end of the winding column 107. The ratchet 108 rotates through the external blocks 106. The other end of a thickened ruler 104 is wound around the surface of the winding column 107. The thickened ruler 104 is also provided with scale lines. A telescopic groove 109 is opened on the side of the external block 106 near the ratchet 108. A telescopic block 110 slides through the telescopic groove 109. A spring is connected between the telescopic block 110 and the telescopic groove 109. A positioning block 111 is fixed at the end of the telescopic block 110. The positioning block 111 fits against the side of the ratchet 108 teeth and can position the ratchet 108.

[0033] When using the sealing strip shearing fixture, the sealing strip needs to be inserted into the workpiece 2 first. Then, the sealing strip is sheared by the cutter of the workpiece 2. To ensure the shearing value of the sealing strip, the ratchet 108 needs to be rotated first. The inclined teeth can then press the side of the positioning block 111. When the positioning block 111 is pressed, it can drive the telescopic block 110 to move. When the telescopic block 110 moves, it can slide through the telescopic groove 109. When the telescopic block 110 slides, it can press the spring. The positioning block 111 is pressed to... After reaching a certain position, the winding column 107 can be driven to rotate. When the winding column 107 rotates, it can be rotated through the outer block 106. When the winding column 107 rotates, it can wind the thickened tape 104 on the surface. When the thickened tape 104 is wound and wound up, it can pull the sliding block 103 to move. The thickened tape 104 will also change direction through the rotating wheel 102 to pull the sliding block 103. When the sliding block 103 is pulled, it can slide through the movable groove 101. When the sliding block 103 slides, it can drive the limit When the limiting block 105 slides, the sliding block 103 can compress the strong spring through the movable groove 101. When the thickened tape 104 is pulled, the scale lines on its surface will move accordingly. The operator can read the value of the limiting block 105's movement based on the scale line values. When the value of the thickened tape 104 reaches the designated position, the telescopic block 110 can be reset by the spring. When the telescopic block 110 resets, it can drive the positioning block 111 to reset. When the positioning block 111 resets, it can be locked onto the plane of the ratchet 108's meshing teeth. Positioning is achieved by positioning block 111. After positioning, ratchet 108 can drive limit block 105 to be positioned. When using the sealing strip, the end needs to be inserted into the side of limit block 105 through machining part 2. Limit block 105 is positioned by a strong spring. Therefore, the position of limit block 105 can be located according to the value of the scale line of thickened ruler 104, thereby determining the length of the sealing strip insertion. After the sealing strip is inserted, the sealing strip can be accurately pulled out, improving the accuracy and efficiency of the tooling sealing strip pulling out.

[0034] Example 2, as follows Figure 2 and Figure 6 The present invention provides the following technical solution: In order to solve the problem that the limiting block 105 of the drawing tool may move after being squeezed by the sealing strip, based on the first embodiment, a squeezing mechanism is disclosed: a through groove 112 is provided through the side of the movable groove 101, and a squeezing mechanism to improve the stability of the measuring mechanism is provided inside the through groove 112. The squeezing mechanism includes a fixed block 113, which is fixed to the side of the sliding block 103 and slides through the through groove 112. A squeezing block 114 is rotatably slid on the surface of the fixed block 113, and a protruding block 115 is fixed at the end of the fixed block 113 away from the sliding block 103.

[0035] When the sealing strip removal fixture adjusts the position of the limiting block 105, the sliding block 103 can slide through the movable groove 101. When the sliding block 103 slides, it can drive the fixed block 113 to move. When the fixed block 113 moves, it can slide through the through groove 112. When the fixed block 113 slides, it can drive the pressing block 114 and the protruding block 115 to move. When the limiting block 105 reaches the designated position, the sliding block 103 can be positioned by a strong spring. To prevent the hard sealing strip from forcefully pressing the limiting block 105, causing a change in the position of the limiting block 105 and affecting the sealing strip removal position, the pressing block 114 needs to be rotated. When the pressing block 114 rotates, it can pass through the surface of the fixed block 113. When the extrusion block 114 rotates to the tilt of the protrusion block 115, it can perform extrusion. Through the extrusion of the tilted surface of the protrusion block 115, the extrusion block 114 will move closer to the side of the housing 1. When the extrusion block 114 rotates to a certain position, it will extrude the tilted surface of the protrusion block 115 and the side of the housing 1. The extrusion of the extrusion block 114 will drive the sliding block 103 to extrude the inner wall of the movable groove 101. After the sliding block 103 is extruded and positioned, it can drive the limiting block 105 to be positioned. Through the strong spring and the extrusion block 114, the sliding block 103 can be dual positioned, which further improves the stability of the limiting block 105 and indirectly improves the accuracy of the sealing strip extraction.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
