Description

Technical Field

[0001] This invention relates to the field of mold inspection tooling technology, specifically to an inspection tooling for automotive parts molds. Background Technology

[0002] The main function of the testing fixture for automotive parts molds is to clamp and transport the automotive window molds onto the testing table, ensuring efficient, safe, and damage-free operation, and to achieve rapid, accurate, and stable positioning of the molds during testing, thus creating the preconditions for subsequent high-precision measurements.

[0003] Patent CN218082345U discloses a testing fixture for automotive parts molds, including a base plate with multiple supports fixedly connected to its bottom. The base plate has an inner cavity with a mounting groove, and a conveyor belt located within the mounting groove is mounted on the base plate. A clamping assembly extending from the bottom to the top of the base plate is provided. A vertical plate is fixedly connected to the top of the base plate, and a horizontal plate is fixedly connected to the right side of the vertical plate. This testing fixture for automotive parts molds transports various automotive parts molds via the conveyor belt and clamps them using the clamping assembly. A scribing assembly then scribes the molds according to the hole positions, diameters, and edges of the automotive parts. By comparing the scribed molds with the parts, testing can be performed. The overall structure achieves cost savings for automotive parts mold testing fixtures, eliminating the need to manufacture dedicated inspection tools for each type of automotive part.

[0004] However, the current inspection fixtures for automotive parts molds have the following problems: during the movement of automotive parts molds, the high frequency of vibration when the inspection fixture holds the molds can easily cause the molds to fall and be damaged. At the same time, the displacement of the clamping assembly can easily cause the clamping assembly to be unstable when clamping downwards. Furthermore, the thread groove of the screw is prone to aging and rusting, which can cause the ring block frame to move and be transported unevenly. Therefore, we propose an inspection fixture for automotive parts molds. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an inspection fixture for automotive parts molds, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a testing fixture for automotive parts molds, comprising: a cabinet with two U-shaped frames embedded in its top surface; a housing fixed to one side of the two U-shaped frames that are close to each other; an L-shaped wide plate fixed to the bottom of the housing; a servo motor mounted on the top surface of the L-shaped wide plate; a screw with both ends penetrating and rotatably mounted on the left side of the L-shaped wide plate and the right side of the inner wall of the housing, the right end of the screw being fixedly connected to the left end of the servo motor's shaft; a ring block frame slidably mounted on the outer wall of the screw; an electro-hydraulic rod penetrating and fixedly mounted in the middle of the bottom surface of the ring block frame; and a T-slot block embedded in the middle of the top surface of the ring block frame. A T-shaped strip is fixed at both ends to the upper left side of an L-shaped wide plate and the right side of the inner wall of the housing, respectively. The inner wall of a T-groove block is slidably connected to the outer wall of the T-shaped strip. The T-groove block slides on the surface of the T-shaped strip. A clamping assembly is fixed to the bottom surface of the telescopic end of an electric hydraulic rod. The clamping assembly tightly clamps the automotive parts mold. The screw rotates clockwise in the housing. Under the constraint of the sliding groove in the housing, the ring block frame slides to the right in the threaded groove of the screw. The ring block frame drives the electric hydraulic rod to slide to the right. The electric hydraulic rod drives the clamping assembly to slide to the right. The clamping assembly drives the automotive parts mold to slide to the right. The ring block frame drives the T-groove block to move to the right, so that the T-groove block slides to the right on the surface of the T-shaped strip through friction, reducing the vibration frequency of the ring block frame.

[0007] According to the above technical solution, a detection module is provided at the bottom of the cabinet, the detection module is inserted through and fixed at the top of the cabinet, a sliding groove is provided on the bottom surface of the housing, the housing is located above the cabinet, the outer wall of the ring block frame slides in contact with the inner wall of the sliding groove of the housing, and the T-shaped strip is located above the screw.

[0008] According to the above technical solution, the outer wall of the screw is provided with a non-self-locking threaded groove, the outer wall of the screw meshes with the inner wall of the ring block frame, and the top surface of the electro-hydraulic rod is fixedly connected to the top of the inner part of the ring block frame.

[0009] According to the above technical solution, the base frame includes an L-shaped frame and two inclined plates. The L-shaped frame is embedded in the left side of the cabinet, and the two inclined plates are fixed to the inner wall of the L-shaped frame. The top of the L-shaped frame is used for placement.

[0010] According to the above technical solution, the clamping assembly includes: an L-shaped plate, two electric telescopic rods and a vertical plate. The L-shaped plate is fixed to the bottom surface of the telescopic end of the electric hydraulic rod. Several rubber strips are provided on the front side of the L-shaped plate. The two electric telescopic rods are provided on the top surface of the L-shaped plate. The vertical plate is fixed to the front side of the telescopic end of the two electric telescopic rods. Several rubber strips are provided on the back side of the vertical plate. The clamping assembly is used to clamp automotive parts molds.

[0011] According to the above technical solution, a limiting device is provided above the outer wall of the ring block frame. The limiting device is used to limit the movement distance of the ring block frame. A lubrication device is provided on the front and back of the limiting device. The lubrication device is used to apply lubricating oil to the thread groove surface of the screw.

[0012] According to the above technical solution, the limiting device includes: a U-shaped plate, which is fixed above the outer wall of the ring block frame; a T-shaped rod, which is fixed in the middle of the left side of the U-shaped plate; two T-groove blocks, which are fixed on the front and back of the U-shaped plate; and two T-shaped strips, which are fixed at the bottom of the inner side of the housing. The inner walls of the two T-groove blocks slide in contact with the outer walls of the two T-shaped strips. The servo motor shaft rotates in reverse, causing the ring block frame to slide the U-shaped plate to the left. The U-shaped plate then moves the T-shaped rod to the left, and the T-groove blocks slide to the left on the surface of the T-shaped strips. During the leftward movement of the T-shaped rod, it contacts the housing wall. The T-shaped rod limits the movement of the ring block frame to the left, allowing the clamping assembly to move above the automotive parts mold.

[0013] According to the above technical solution, a U-shaped plate is fixed to the right side of the U-shaped plate, and a T-shaped rod is slidably installed in the middle of the right side of the U-shaped plate. A spring is provided between the outer wall of the T-shaped rod and the right side of the U-shaped plate. The left side of the L-shaped wide plate is on the movement trajectory of the right side of the T-shaped rod. When the T-shaped rod moves to the right, it contacts the wall of the machine casing. Under the action of the extrusion force, the T-shaped rod slides to the right in the U-shaped plate, and the spring on the T-shaped rod begins to contract, so that the ring block frame will not hit the sliding groove wall of the machine casing.

[0014] According to the above technical solution, the lubrication device includes: a spiral rod fixed to the front and back of a spiral plate; two tube plates fixed to the outer wall of the spiral rod; an annular shell fixed to one side of the two tube plates that are close to each other; and a sponge ring fixed to the inner wall of the annular shell. The sponge ring absorbs lubricating oil and is slidably disposed on the outer wall of the screw. The tube plates drive the annular shell to move to the right, and the annular shell drives the sponge ring to move to the right. The sponge ring slides on the surface of the screw and wipes the lubricating oil onto the surface of the screw. The sponge ring is used to wipe the surface of the screw.

[0016] This invention provides an inspection fixture for automotive parts molds. It has the following advantages:

[0017] (1) The present invention uses a cabinet, a detection module, a base frame, a U-shaped frame, a housing, an L-shaped wide plate, a servo motor, a screw, a ring block frame, an electric hydraulic rod, a T-slot block and a T-shaped strip plate to cooperate with a clamping assembly. The clamping assembly tightly clamps the automotive parts mold. The screw rotates clockwise in the housing. Under the restriction of the sliding groove in the housing, the ring block frame slides to the right in the threaded groove of the screw. The ring block frame drives the electric hydraulic rod to slide to the right. The electric hydraulic rod drives the clamping assembly to slide to the right. The clamping assembly drives the automotive parts mold to slide to the right. The ring block frame drives the T-slot block to move to the right, so that the T-slot block slides to the right on the surface of the T-shaped strip plate through friction, reducing the shaking frequency of the ring block frame and preventing the automotive parts mold from falling and being damaged due to excessive shaking frequency of the ring block frame.

[0018] (2) By setting the limiting device, the present invention enables the return plate, T-shaped rod one and T-groove block two to cooperate with T-shaped strip plate two, the servo motor shaft to reverse, the ring block frame to drive the return plate to slide to the left, the return plate to drive T-shaped rod one to move to the left, T-groove block two to slide to the left on the surface of T-shaped strip plate two, and T-shaped rod one to move to the left and contact the casing wall. The T-shaped rod one is limited by the ring block frame, so that the clamping mold assembly moves to the top of the bottom frame, preventing the clamping mold assembly from shifting and causing unstable downward clamping of the clamping mold assembly.

[0019] (3) By setting the limiting device, the U-shaped plate and the T-shaped rod 2 cooperate with the spring. When the T-shaped rod 2 moves to the right, it contacts the wall of the machine casing. Under the action of the extrusion force, the T-shaped rod 2 slides to the right in the U-shaped plate, and the spring on the T-shaped rod 2 begins to contract, so that the ring block frame will not hit the sliding groove wall of the machine casing, and prevent the ring block frame from hitting the sliding groove wall of the machine casing and causing damage to the ring block frame.

[0020] (4) The present invention, through the setting of the lubrication device, enables the return rod, tube plate and ring shell to cooperate with the sponge ring. The tube plate drives the ring shell to move to the right, the ring shell drives the sponge ring to move to the right, the sponge ring slides on the surface of the screw, and the sponge ring wipes the lubricating oil on the surface of the screw to prevent the screw thread groove from aging and rusting, which would cause the ring block frame to move and transport poorly.

[0021] (5) The present invention, through the setting of the lubrication device, makes the ring tube and the L-shaped short plate cooperate with the plate, the plate supports the movement of the L-shaped short plate, the L-shaped short plate supports the movement of the ring tube, and the ring tube supports the movement of the spiral rod, so as to prevent the spiral rod from being unstable and causing poor wiping effect of the sponge ring.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Please see Figures 1-8 One embodiment of the present invention is: a testing fixture for automotive parts molds, comprising: a cabinet 1, and a base frame 3 comprising: an L-shaped frame 301 and two inclined plates 302. The L-shaped frame 301 is embedded in the left side of the cabinet 1, and the two inclined plates 302 are fixed on the inner wall of the L-shaped frame 301. The upper part of the L-shaped frame 301 is used for placing.

[0033] The top surface of the cabinet 1 has two U-shaped frames 4 embedded in it, a housing 5 fixed to one side of the two U-shaped frames 4 that are close to each other, an L-shaped wide plate 6 fixed to the bottom of the housing 5, a servo motor 7 set on the top surface of the L-shaped wide plate 6, a screw 8 with both ends passing through and rotatably mounted on the left side of the L-shaped wide plate 6 and the right side of the inner wall of the housing 5 respectively, the right end of the screw 8 fixedly connected to the left end of the shaft of the servo motor 7, a ring block frame 9 slidably mounted on the outer wall of the screw 8, an electro-hydraulic rod 10 passing through and fixedly mounted in the middle of the bottom surface of the ring block frame 9, a T-slot block 11 embedded in the middle of the top surface of the ring block frame 9, and a T-shaped strip 12. The two ends of the T-shaped strip 12 are respectively fixed to the upper left side of the L-shaped wide plate 6 and the right side of the inner wall of the housing 5. The inner wall of the T-shaped block 11 is slidably connected to the outer wall of the T-shaped strip 12. The T-shaped block 11 slides on the surface of the T-shaped strip 12. The bottom of the cabinet 1 is provided with a detection module 2. The detection module 2 passes through and is fixed to the top of the cabinet 1. The bottom surface of the housing 5 is provided with a sliding groove. The housing 5 is located above the cabinet 1. The outer wall of the ring block frame 9 slides in contact with the inner wall of the sliding groove of the housing 5. The T-shaped strip 12 is located above the screw 8. The outer wall of the screw 8 is provided with a non-self-locking threaded groove. The outer wall of the screw 8 meshes with the inner wall of the ring block frame 9. The top surface of the electric hydraulic rod 10 is fixedly connected to the top of the ring block frame 9.

[0034] The clamping assembly 13 is fixed to the bottom surface of the telescopic end of the electric hydraulic rod 10. The clamping assembly 13 includes: an L-shaped plate 01, two electric telescopic rods 02 and a vertical plate 03. The L-shaped plate 01 is fixed to the bottom surface of the telescopic end of the electric hydraulic rod 10. Several rubber strips are provided on the front side of the L-shaped plate 01. The two electric telescopic rods 02 are provided on the top surface of the L-shaped plate 01. The vertical plate 03 is fixed to the front side of the telescopic end of the two electric telescopic rods 02. Several rubber strips are provided on the back side of the vertical plate 03. The clamping assembly 13 is used to clamp automotive parts molds.

[0035] When using this device, the cabinet 1 supports the base frame 3. The operator places the automotive parts mold on the L-shaped frame 301, which is supported by the inclined plate 302. The operator activates the electric hydraulic rod 10 on the ring block frame 9. The telescopic end of the electric hydraulic rod 10 begins to move downward, which in turn moves the clamping assembly 13 downward. The telescopic end of the electric hydraulic rod 10 then moves the L-shaped plate 01 downward. Once the L-shaped plate 01 is above the automotive parts mold, the operator activates the electric telescopic rod 02. The telescopic end of the electric telescopic rod 02 moves the vertical plate 03 backward, which tightly clamps the automotive parts mold. The telescopic end of the electric hydraulic rod 10 returns to its original position. The operator then activates the servo motor 7 in the L-shaped wide plate 6. The shaft of the servo motor 7 begins to rotate forward, which in turn drives the screw 8 to rotate forward. The screw 8 rotates forward within the housing 5. The U-shaped frame 4 supports the housing 5. Under the constraint of the sliding groove of the housing 5, the ring block frame 9 slides to the right in the threaded groove of the screw 8. The ring block frame 9 slides to the right in the sliding groove of the housing 5. The ring block frame 9 drives the electric hydraulic rod 10 to slide to the right. The electric hydraulic rod 10 drives the clamping mold assembly 13 to slide to the right. The clamping mold assembly 13 drives the automotive parts mold to slide to the right. At the same time, the ring block frame 9 drives the T-slot block 11 to move to the right, so that the T-slot block 11 slides to the right on the surface of the T-shaped strip 12 through friction, reducing the shaking frequency of the ring block frame 9. This avoids the problem of the automotive parts mold falling and being damaged due to the excessive shaking frequency of the ring block frame 9 when the inspection fixture moves the automotive parts mold. When the clamping mold assembly 13 clamps the automotive parts mold to the right side of the inspection module 2, the telescopic end of the electric hydraulic rod 10 drives the clamping mold assembly 13 to move downward. The automotive parts mold moves to the top of the cabinet 1, and the inspection module 2 inspects the surface of the automotive parts mold.

[0036] A limiting device 14 is provided on the upper part of the outer wall of the ring block frame 9. The limiting device 14 is used to limit the movement distance of the ring block frame 9. A lubrication device 15 is provided on the front and back of the limiting device 14. The lubrication device 15 is used to apply lubricating oil to the thread groove surface of the screw 8.

[0037] Working principle: The automotive part mold is placed on the L-shaped frame 301. The telescopic end of the electric hydraulic rod 10 drives the clamping assembly 13 to move downwards. The telescopic end of the electric hydraulic rod 10 drives the L-shaped plate 01 to move downwards. The L-shaped plate 01 moves above the automotive part mold. The telescopic end of the electric telescopic rod 02 drives the vertical plate 03 to move backwards. The vertical plate 03 tightly clamps the automotive part mold. The telescopic end of the electric hydraulic rod 10 returns to its original position. The rotating shaft of the servo motor 7 drives the screw 8 to rotate forward. The screw 8 rotates forward in the housing 5. Under the constraint of the sliding groove in the housing 5, the ring block frame 9 slides to the right in the threaded groove of the screw 8. 9 slides to the right in the groove of the housing 5. The ring block frame 9 drives the electric hydraulic rod 10 to slide to the right. The electric hydraulic rod 10 drives the clamping mold assembly 13 to slide to the right. The clamping mold assembly 13 drives the automotive parts mold to slide to the right. The ring block frame 9 drives the T-slot block 11 to move to the right. The T-slot block 11 slides to the right on the surface of the T-shaped strip 12 through friction. When the clamping mold assembly 13 clamps the automotive parts mold to the right side of the detection module 2, the telescopic end of the electric hydraulic rod 10 drives the clamping mold assembly 13 to move downward. The automotive parts mold moves to the top of the cabinet 1, and the detection module 2 detects the surface of the automotive parts mold.

[0038] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the limiting device 14 includes: a U-shaped plate 141, which is fixed above the outer wall of the ring block frame 9; a T-shaped rod 142, which is fixed in the middle of the left side of the U-shaped plate 141; two T-groove blocks 143, which are fixed on the front and back sides of the U-shaped plate 141; and two T-shaped strips 144, which are fixed in the bottom of the inner side of the housing 5. The inner walls of the two T-groove blocks 143 slide in contact with the outer walls of the two T-shaped strips 144. The T-shaped rod 142 is used to limit the distance the ring block frame 9 moves to the left, so that the clamping mold assembly 13 moves above the automotive parts mold.

[0039] As the ring block frame 9 slides to the right in the groove of the housing 5, it drives the return plate 141 to slide to the right. The return plate 141 drives the T-shaped rod 142 to move to the right, and the return plate 141 drives the T-groove block 143 to slide to the right. The T-groove block 143 slides to the right on the surface of the T-shaped strip 144. When the automotive parts mold inspection is completed, the telescopic end of the electric hydraulic rod 10 drives the clamping assembly 13 to move upward, the shaft of the servo motor 7 reverses, and the ring block frame 9 drives the return plate 142 to move to the right. The forming plate 141 slides to the left, and the return plate 141 drives the T-shaped rod 142 to move to the left. The T-groove block 143 slides to the left on the surface of the T-shaped strip 144. During the process of the T-shaped rod 142 moving to the left, it contacts the wall of the housing 5. The T-shaped rod 142 limits the ring block frame 9, allowing the clamping mold assembly 13 to move above the bottom frame 3. This avoids the problem that the clamping mold assembly 13 is unstable when it moves the automotive parts mold and the inspection fixture moves.

[0040] A U-shaped plate 145 is fixed to the right side of the U-shaped plate 141. A T-shaped rod 146 is slidably installed in the middle of the right side of the U-shaped plate 145. A spring 147 is provided between the outer wall of the T-shaped rod 146 and the right side of the U-shaped plate 145. The left side of the L-shaped wide plate 6 is on the movement trajectory of the right side of the T-shaped rod 146.

[0041] As the U-shaped plate 141 drives the T-slot block 143 to slide to the right, the U-shaped plate 141 also drives the U-shaped plate 145 to slide to the right. The U-shaped plate 145 then drives the T-shaped rod 146 to move to the right. During its movement to the right, the T-shaped rod 146 contacts the wall of the housing 5. Under the pressure, the T-shaped rod 146 slides to the right within the U-shaped plate 145. The spring 147 on the T-shaped rod 146 begins to contract, preventing the ring block frame 9 from hitting the sliding groove wall of the housing 5. This avoids the problem of the ring block frame 9 being damaged by hitting the sliding groove wall of the housing 5 when the inspection fixture moves the automotive parts mold.

[0042] The lubrication device 15 includes: a spiral rod 151, which is fixed to the front and back of the spiral plate 141; two tube plates 152, which are fixed to the outer wall of the spiral rod 151; an annular shell 153, which is fixed to the side of the two tube plates 152 that are close to each other; and a sponge ring 154, which is fixed to the inner wall of the annular shell 153. The sponge ring 154 absorbs lubricating oil inside and is slidably disposed on the outer wall of the screw 8. The sponge ring 154 is used to wipe the surface of the screw 8.

[0043] While the U-shaped plate 145 drives the T-shaped rod 146 to move to the right, the U-shaped plate 145 drives the return rod 151 to move to the right, the return rod 151 drives the tube plate 152 to move to the right, the tube plate 152 drives the ring shell 153 to move to the right, the ring shell 153 drives the sponge ring 154 to move to the right, and the sponge ring 154 slides on the surface of the screw 8, wiping the lubricating oil on the surface of the screw 8. This avoids the problem of the screw 8's thread groove aging and rusting, which would cause the ring block frame 9 to move and be transported unevenly when the inspection fixture moves the automotive parts mold.

[0044] A ring tube 155 is fixed above the outer wall of the spiral rod 151. An L-shaped short plate 156 is fixed to the ring tube 155. A plate 157 is fixed to the bottom surface of the L-shaped short plate 156. The bottom surface of the plate 157 is fixedly connected to the top surface of the T-groove block 11.

[0045] While the return rod 151 moves the tube plate 152 to the right, the return rod 151 also moves the ring tube 155 to the right. The ring tube 155 moves the L-shaped short plate 156 to the right, and the L-shaped short plate 156 moves the plate 157 to the right. The plate 157 supports the movement of the L-shaped short plate 156, the L-shaped short plate 156 supports the movement of the ring tube 155, and the ring tube 155 supports the movement of the return rod 151. This avoids the problem of poor wiping effect of the sponge ring 154 caused by the unstable support of the return rod 151 when the inspection fixture moves the automotive parts mold.

[0046] Working principle: The ring block frame 9 drives the spiral plate 141 to slide to the right, the spiral plate 141 drives the T-slot block 143 to slide to the right, the T-slot block 143 slides to the right on the surface of the T-shaped strip 144, the shaft of the servo motor 7 reverses, the ring block frame 9 drives the spiral plate 141 to slide to the left, the spiral plate 141 drives the T-shaped rod 142 to move to the left, the T-slot block 143 slides to the left on the surface of the T-shaped strip 144, and the T-shaped rod 142 contacts the wall of the housing 5 during the process of moving to the left;

[0047] The U-shaped plate 141 drives the U-shaped plate 145 to slide to the right, and the U-shaped plate 145 drives the T-shaped rod 146 to move to the right. During the movement to the right, the T-shaped rod 146 contacts the wall of the machine casing 5. Under the action of the extrusion force, the T-shaped rod 146 slides to the right in the U-shaped plate 145, and the spring 147 on the T-shaped rod 146 begins to contract.

[0048] U-shaped plate 145 drives the spiral rod 151 to move to the right, the spiral rod 151 drives the tube plate 152 to move to the right, the tube plate 152 drives the ring shell 153 to move to the right, the ring shell 153 drives the sponge ring 154 to move to the right, and the sponge ring 154 slides on the surface of the screw 8.

[0049] Plate 157 supports the movement of L-shaped short plate 156, L-shaped short plate 156 supports the movement of ring tube 155, and ring tube 155 supports the movement of spiral rod 151.

[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
