Description

Technical Field

[0001] The utility model relates to the technical field of machining of mechanical parts, and particularly relates to a grinding device for mechanical parts. Background Art

[0002] A grinding device for mechanical parts is a device used for grinding, polishing and processing the surface of mechanical parts. Its main purpose is to improve the surface finish of parts, reduce surface defects, and improve the wear resistance and service life of parts. The grinding device is usually applied in fields such as manufacturing, automotive industry, aerospace, etc. For example, during the welding process of frame-shaped parts, unevenness occurs at the welded joints around the plane, so a grinding device is needed to grind the uneven welds.

[0003] During the use of the existing grinding device, generally, the frame-shaped parts to be ground are manually placed in the trough provided at the top of the lifting support plate, and the frame parts are limited by the V-shaped limiting groove. At the same time, during the grinding process, since there is no structure for fixing the frame parts on the lifting support plate, it is necessary to manually press and fix the frame parts to grind the welds at the four corners and edges, resulting in inconvenience and potential safety hazards to the staff during the grinding process. Therefore, this application provides a grinding device for mechanical parts to meet the requirements. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a grinding device for mechanical parts to solve the problem that when the existing grinding device for mechanical parts grinds frame parts, due to the lack of a fixing structure for the frame parts, it is necessary to manually press and fix the frame parts for grinding, which brings inconvenience and certain potential safety hazards to the grinding staff.

[0005] To solve the above technical problem, the utility model provides the following technical solutions:

[0006] A grinding device for mechanical parts, including a support frame body. At the top of the support frame body, a guide seat a with a vertically cross-sectional hourglass-shaped structure is fixedly connected. A U-shaped movable seat is slidably sleeved on the top of the guide seat a. A grinding machine is fixed on the U-shaped movable seat through a fixing device. At the bottom end of the output shaft of the grinding machine, a grinding disc is fixedly connected. At the rear side of the U-shaped movable seat, an electric telescopic rod a fixedly connected to the top of the guide seat a is provided. The extending ends of the electric telescopic rod a are fixedly connected to the inner bottom wall of the U-shaped movable seat through push-pull blocks. On the front side wall of the support frame body, a guide seat b with a horizontally cross-sectional hourglass-shaped structure is fixedly connected. A lifting support plate is slidably sleeved on the outside of the guide seat b. A support groove is opened at the top of the lifting support plate. A V-shaped limiting groove is provided at a position close to the guide seat b in the support groove. A frame member to be ground is placed movably in the support groove. Below the lifting support plate, an electric telescopic rod b fixedly connected to the front side wall of the guide seat b is provided. The extending end of the electric telescopic rod b is fixedly connected to the bottom end of the lifting support plate. Two adjustable fixing members are symmetrically arranged and installed in the support groove provided at the top of the lifting support plate. The adjustable fixing members are used to fix the frame member.

[0007] Optionally, the two adjustable fixing members are vertically distributed.

[0008] Optionally, the adjustable fixing member includes a support block provided on the inner bottom wall of the support groove. A clamping plate is fixedly connected to the top of the support block. A displacement adjusting component is connected between the bottom end of the support block and the inner bottom wall of the support groove. A buckle strip with a vertically cross-sectional inverted L-shaped structure is fixedly connected to the top of the clamping plate. The top vertical cross-section of the buckle strip is in a right-angled triangle structure. A weakening groove a is provided between the bottom end of the buckle strip and the top of the clamping plate.

[0009] Optionally, the support block has a hollow structure, and the clamping surface of the clamping plate is flush with the surface of the support block facing the V-shaped limiting groove.

[0010] Optionally, the buckle strip is made of ABS plastic material.

[0011] Optionally, the displacement adjusting component includes a sliding seat fixedly connected to the bottom end of the support block. The vertical cross-section of the sliding seat is in a convex structure. The sliding seat is slidably connected to a sliding groove opened on the inner bottom wall of the support groove.

[0012] Optionally, C-shaped plates with a vertically cross-sectional C-shaped structure are fixedly connected to both side walls of the sliding seat. A weakening groove b is provided at one end of the C-shaped plate connected to the sliding seat. The other end of the C-shaped plate has an arc-shaped bending part.

[0013] Optionally, two symmetrically arranged mating grooves are provided at the bottom end of the support base. The mating grooves are all movably sleeved on the outer side of the connecting strip. One end of each connecting strip is fixedly connected to the inner wall of the V-shaped limiting groove. The vertical cross-section of the mating groove is in a right-angled triangle structure. A plurality of equally spaced teeth a are fixedly connected to the outer arc surfaces of the two C-shaped plates facing away from each other. A plurality of equally spaced teeth b are fixedly connected to the inclined surface a provided at the top end of the connecting strip. The C-shaped plates are all fixedly clamped on the corresponding teeth b through a plurality of teeth a.

[0014] Optionally, a gap for the plurality of teeth b to pass through is reserved between the inclined surface b provided on the inner wall of the mating groove and the inclined surface a. The teeth b are all arranged parallel to the teeth a.

[0015] Optionally, the C-shaped plates and the arc-shaped bending parts are also made of ABS plastic material.

[0016] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0017] In the above solution, by setting the adjustable fixing member, in combination with the setting of the buckling strip and the weakening groove, when fixing the frame member, the bottom end of the frame member is directly pressed against the top of the two buckling strips. Due to the setting of the weakening groove a, the buckling strip bends away from the V-shaped limiting groove, so as to facilitate the frame member to continue to move downward until the buckling strip is fixed to the top of the frame member under the rebounding action of the weakening groove a, avoiding the phenomenon of the frame member moving up and down when grinding the weld position. At the same time, in combination with the setting of the clamping plate, the fixing effect on the frame member is further improved. In addition, after the four corners of the frame member are ground, the two buckling strips can be manually bent outward, and at this time, the frame member can be manually lifted upward to facilitate the disassembly of the frame member. Compared with the prior art, there is no need to manually press the fixed frame member, which is very convenient and fast during fixing, and at the same time effectively reduces the possibility of potential safety hazards during the grinding process.

[0018] By setting the displacement adjustment assembly, by manually squeezing the two arc-shaped bending parts, in combination with the setting of the weakening groove b, the plurality of teeth a provided on the outer arc surfaces of the two C-shaped plates facing away from each other are all disengaged from the engagement with the plurality of teeth b, so that each fixing member can achieve displacement adjustment, and thus it is possible to facilitate the limit fixing of frame members with different wall thicknesses, greatly improving the applicable range of the mechanical part grinding device.

[0032] Such as Figure 1 and Figure 2As shown in the figure, an embodiment of the present utility model provides a mechanical part grinding device, which includes a support frame body 1. At the top of the support frame body 1, a guide seat a 2 with a vertically cross-sectional hourglass-shaped structure is fixedly connected. A U-shaped movable seat 21 is slidably sleeved at the top of the guide seat a 2. A grinding machine 23 is fixed on the U-shaped movable seat 21 through a fixing device 22. At the bottom end of the output shaft of the grinding machine 23, a grinding disc 24 is fixedly connected. At the rear side of the U-shaped movable seat 21, an electric telescopic rod a 25 fixedly connected to the top of the guide seat a 2 is provided. The telescopic ends of the electric telescopic rod a 25 are fixedly connected to the inner bottom wall of the U-shaped movable seat 21 through push-pull blocks 26. On the front side wall of the support frame body 1, a guide seat b 3 with a horizontally cross-sectional hourglass-shaped structure is fixedly connected. A lifting support plate 31 is slidably sleeved outside the guide seat b 3. A support groove 32 is opened at the top of the lifting support plate 31. At a position close to the guide seat b 3 in the support groove 32, a V-shaped limiting groove 33 is provided. A frame member 4 to be ground is placed in the support groove 32 movably. Below the lifting support plate 31, an electric telescopic rod b 34 fixedly connected to the front side wall of the guide seat b 3 is provided. The telescopic end of the electric telescopic rod b 34 is fixedly connected to the bottom end of the lifting support plate 31. Two symmetrically arranged adjustable fixing members 5 are installed in the support groove 32 provided at the top of the lifting support plate 31. The adjustable fixing members 5 are used to fix the frame member 4.

[0033] As Figures 2 to 4 shown, in order to facilitate the rapid fixation of the frame member 4, the two adjustable fixing members 5 are arranged vertically. The adjustable fixing member 5 includes a support block 51 provided on the inner bottom wall of the support groove 32. At the top of the support block 51, a clamping plate 52 is fixedly connected. A displacement adjusting assembly is connected between the bottom end of the support block 51 and the inner bottom wall of the support groove 32. At the top of the clamping plate 52, a buckling strip 53 with a vertically cross-sectional inverted L-shaped structure is fixedly connected. The top vertically cross-section of the buckling strip 53 is in a right-angled triangle structure. A weakening groove a 54 is provided between the bottom end of the buckling strip 53 and the top of the clamping plate 52. The support block 51 is in a hollow structure. The clamping surface of the clamping plate 52 is flush with the surface of the support block 51 facing the V-shaped limiting groove 33. The buckling strip 53 is made of ABS plastic material.

[0034] Among them, the setting of the weakening groove a 54 enables the buckling strip 53 to be manually bent. The support block 51 is in a hollow structure to reduce the overall weight and avoid excessive gravity from interfering with the lifting of the lifting support plate 31. The top vertically cross-section of the buckling strip 53 being in a right-angled triangle structure enables the setting of the top inclined surface of the buckling strip 53 to facilitate the frame member 4 to directly press against the inclined surface when being placed and fixed, so that the buckling strip 53 deforms in cooperation with the weakening groove a 54 until it presses against the top of the completely placed frame member 4.

[0035] As Figures 2 to 4As shown in the figure, in order to facilitate the adjustment of the position of the above-mentioned fixing member to meet the fixing of the frame member 4 with different wall thicknesses, the displacement adjustment assembly is provided to include a sliding seat 55 fixedly connected to the bottom end of the support block 51. The vertical cross-section of the sliding seat 55 is of a convex structure. The sliding seat 55 is slidably connected to a sliding groove opened in the inner bottom wall of the support groove 32. C-shaped plates 56 with a vertical cross-section of a C-shaped structure are fixedly connected to both side walls of the sliding seat 55. A weakening groove b57 is provided at one end of the C-shaped plate 56 connected to the sliding seat 55. The other end of the C-shaped plate 56 is provided with an arc-shaped bending portion 58. Two symmetrically arranged mating grooves 510 are opened at the bottom end of the support seat. The mating grooves 510 are all movably sleeved on the outer side of the connecting bar 511. One end of each connecting bar 511 is fixedly connected to the inner wall of the V-shaped limiting groove 33. The vertical cross-section of the mating groove 510 is of a right-angled triangle structure. A plurality of equally spaced tooth a59 are fixedly connected to the outer arc surfaces of the two C-shaped plates 56 facing away from each other. A plurality of equally spaced tooth b512 are fixedly connected to the inclined surface a provided at the top end of the connecting bar 511. The C-shaped plates 56 are all snap-fitted and fixed to the corresponding tooth b512 by a plurality of tooth a59. A gap for the plurality of tooth b512 to move through conveniently is reserved between the inclined surface b provided on the inner wall of the mating groove 510 and the inclined surface a. The tooth b512 are all arranged parallel to the tooth a59. The C-shaped plates 56 and the arc-shaped bending portions 58 are also all made of ABS plastic material.

[0036] Among them, the setting of the weakening groove b57 enables the two C-shaped plates 56 to deform when manually pinching the two arc-shaped bending portions 58, so that the plurality of tooth a59 are disengaged from the snap-fitting with the corresponding plurality of tooth b512. The setting of the plurality of tooth b512 fixed to the inclined surface a at the top end of the connecting bar 511 enables the plurality of tooth a59 to be more conveniently disengaged from the snap-fitting with the plurality of tooth b512 when pinching the two arc-shaped bending portions 58, avoiding displacement interference caused by incomplete disengagement. In addition, the setting of the gap is to facilitate the movement of the support seat and avoid the influence of the tooth b512 on the movement of the support seat.

[0037] The working principle of the technical solution provided by the present utility model is as follows: The operator can first adjust the positions of the two support seats according to the wall thickness of the frame member 4. When manually pinching the two arc-shaped bent portions 58, in cooperation with the setting of the weakening groove b57, the two C-shaped plates 56 can be deformed, so that the multiple teeth a59 are disengaged from the engagement with the corresponding multiple teeth b512, and then the positions of the support seat, the clamping plate 52, and the clamping strip 53 can be adjusted and moved until the placed frame member 4 is clamped and pressed. After that, when installing the frame member 4 with the same size as above, the frame member 4 can be directly pressed in from the top of the two clamping strips 53, so as to quickly fix the frame member 4. Then, the electric telescopic rod b34 is used to push the lifting support plate 31 to rise, and in cooperation with the electric telescopic rod a25 to push the grinding disk 24 driven by the grinding machine 23 to move forward, so that the welds at the four corners of the top end of the frame member 4 can be ground smoothly. There is no need for manual pressing and fixing of the frame member 4 anymore. The fixing is very convenient and fast, and at the same time, the possibility of potential safety hazards during the grinding process is effectively reduced.

[0038] The present utility model covers any substitutions, modifications, equivalent methods, and solutions made on the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the following preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without these detailed descriptions. In addition, well-known methods, processes, procedures, components, and circuits are not described in detail to avoid unnecessary confusion to the essence of the present utility model.

[0039] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
